Cooperation and Critique in Neuroscience: Loops of Feedback Between Philosophy, the Psy Sciences and Neurophenomenology

In the long history of tenuous relations between psychology, psychiatry and philosophy the rise of neuroscience is typically regarded as decisive turn towards biological reductionism. Roughly since the turn of the millennium, however, the story has become more complicated. The emergence of social and cultural neuroscience seemed to indicate a new trend toward interdisciplinary cooperation across the nature-culture divide. Situating the emergence of this transdisciplinary agenda in the longer history of biologicalization in psychiatry and neuroscience, however, allows differentiating a mere rhetoric of bridging between neuroscience and humanities from conceptually more stringent studies such as in neurophenomenology. While some actors developed sophisticated experimental settings here for mediating between opposing approaches, others contributed by performative interventions, as critique comes in different forms and formats. In effect, these different lines of work keep the question regarding human nature open; certainly not the least achievement.


Introduction
"The central problem of the human sciences remains unresolved," the incoming editors of the journal History of the Human Sciences recently stated: "Despite the new claims championed within molecular biology, evolutionary psychology, artificial intelligence and the cognitive neurosciences, one of the central organizing categories of each of those disciplines -the human -has resisted definition." 1 After many years of massive research, such a statement may sound like the deconstruction of a scientific ethos, but the lamentable diagnosis was certainly meant as good news for the intellectual endeavor of the human sciences: So far, attempts to take the human and the question of human nature as being merely an empirical problem awaiting to be solved by innovative technologies of observation and experimental intervention have failed to arrive at convincing and comprehensive answers. Not that these projects did not deliver a wealth of data and information, but the debate on their significance continues -and rightly so. Protracted deliberations on human nature are suitable ways to keep society going, to protect the social organism, to care for and cultivate the achieved.
Writing for Le foucaldien on the shifting relations between psychology and philosophy in light of the neurosciences brings up Michel Foucault's famous dictum that "man is a recent invention" of European culture, "and one perhaps nearing its end." 2 The human sciences, and psychology in particular, are certainly "an invention of recent date" within the history of knowledge. One and a half centuries after establishing psychology as laboratory science and with neuroscience as the latest offspring in this history of experimentalization, brain research currently colonizes the human sciences and aims to reduce them to new branches and provinces of neuroscience, confirming Michel Foucault's gloomy prophecy in unprecedented and then unexpected ways. The recent rise of neuroscience seems to confirm at least a specific interpretation of Foucault's prophecy: Aren't the advances of brain research Arguing along similar lines, Fernando Vidal and Francisco Ortega warn, in their recent book Being Brains, that the brain sciences thrive on an ideology and mere creed, because their dominance has not (yet) been justified by any major scientific breakthroughs. 4 Sharing their concerns and agreeing with their analysis in general, I want to escape the totalizing gaze implicit in their diagnosis: The neurosciences are a moving target, certainly in terms of technological advances, but also with regard to changing methods and theoretical orientations. These may not replace abruptly neuro-based explanations with introspective accounts and socio-political processes, but the boisterous reductionism from the days of the Decade of the Brain seems to have meanwhile cleared the way for more comprehensive approaches and more cooperative relations with the humanities. In an afterword to a collection of essays on Transdisciplinarity in the Age of the Brain, Joseph Dumit has recently described these shifting relations between brain sciences and humanities with the metaphor of "twisting the neurohelix." 5 Does this trend towards transdisciplinary cooperation entail new perspectives for the psy sciences or does it, on the contrary, require new critical interventions from different angles? 6 And does this shift indicate that neuroscientists learned from the waves of critique, which the rise of reductionist neuroscience had kindled, and did they do so in more but strategic ways?
Such questions are obviously far too broad for being addressed and answered in this single paper. In addition, they rely on a rather monolithic conceptualization of neuro that ignores the complexity and diversity of this vast field of research. The diagnosis of the neuro, however, has become so dominant and seems to be so widely shared among actors from both sides of the divide that it has lost much of its critical potential. Instead of continuing along this ostensibly clear-cut opposition between bioscientific attempts to explain "the human" and their critique by the social and human sciences, I suggest to look at the effects of critique and the forms of cooperation: How do critique and cooperation articulate as forms of feedback and how did they contribute to the trends and developments in the field? Does transdiscip- Varela and how he takes the hard problem seriously, I want to discuss his version of neurophenomenology as a radical form of philosophical critique, extending the genealogy from Kant's fundamental analysis of antinomies via Husserl to cognitive science. The paper concludes in section 5 by contrasting more recent studies that build on Varela by building sophisticated experimental settings with a performative form of critique, exploiting the productive potential of constraints rather than viewing them as epistemic limitations. This form of critique, revolving around feedback 7 Bruno Latour, "Why has critique run out of steam? From matters of fact to matters of concern," Criti-

Foucault wrote Les mots et les choses more than half a century ago. Published in 1966, the book propelled its author to international visibility in the emerging movement for radical critique and social revolution for which "1968" now stands as global signifier. 8 Its semicentennial in 2018 saw a re-evaluation of the international student movements as turning point towards liberalism on the one hand and terrorism on the other, 9 but most agree that Foucault and his allies started a "long-lasting summer of theory", according to Philipp Felsch's swan-song on this intellectual debate. 10 In the psy sciences, the changing approaches to "our thought" played out particularly strongly in the arena of mental health, where multiplying initiatives for dehospitalization were to transform psychiatric practice during the 1970s, and with it an understanding of the human. 11 In parallel with, though unrelated to, these institutional changes, an epistemic transformation of psychiatry as academic discipline set in, a trend towards focusing on the brain and biological processes, as indicated by the revisions for the third edition of the Diagnostic and Statistical Manual (DSM-III) in 1980. 12 Leading psychiatrists started to promote a re-orientation towards biolo-  Revolte 1960-1990, (München: Beck, 2015. 11 Despo Kritsotaki, Vicky Long and Matthew Smith, eds., Deinstitutionalisation and after: post-war psychiatry in the western world (Cham: Palgrave Macmillan, 2016). 12 Diagnostic and statistical manual of mental disorders, ed.

Borck: Cooperation and Critique in Neuroscience 6
Griesinger had proclaimed already 150 years ago, namely that "psychiatry is moving from the 'troubled mind' to the 'broken brain'." 13 Professionals and historians agree that the psy sciences have undergone a massive shift towards molecular biology and the brain sciences in this process, away from psychological and psychodynamic theorizing 14 -a transformation meanwhile lamented even by some of its former advocates. 15 This shifting orientation in psychiatry pre-dated the American President declaring the final ten years of the millennium to be the Decade of the Brain with the ensuing intensification of neuroscientific research. Early forms of functional imaging had made headlines during the 1980s and had kindled hopes to turn brain visualization into a diagnostic tool for mental illnesses. Neuroimaging still has to deliver on that front, but it nonetheless emerged as powerful domain during the 1990s. 16 Braincentered research now dominated the psy sciences and it was as heavily celebrated as criticized. Neuro-popularizer Susan Greenfield, for example, got appointed CBE in Britain for explaining the brain to the wider public, 17 while American psychologist William Uttal diagnosed the rise of a New Phrenology in psychology's attempts to establish itself as brain science. 18 In Germany, eleven "leading brain researchers" published an infamous "manifesto" on how best to adapt society to the insights 13 Nancy C. Andreasen, The broken brain: the biological revolution in psychiatry, (New York, NY: Harper & Row, 1984), viii. 14 Andrew Scull, "Contending Professions: Sciences of the Brain and Mind in the United States, 1850- Society as "journal of cognitive and epistemological studies on economics and social sciences." 22 Neurophilosophy got advertised as "unified science of mind and brain", and neuroethics was introduced as "anticipating the future". 23 Already this brief list indicates that many of the newer approaches thrived on multi-disciplinary perspectives. This is a distinctive feature of much research in neuroscience in general as it was an effect of the massive investment in this domain. Particular attention by the public sphere was gained by experimental approaches that bridged across the nature/culture divide and addressed phenomena at the intersection of brain, mind, and society.
The promise was to find new scientific ground for social and philosophical questions. 19  In part, this trend was a consequence of technological advances in neuroimaging. 24 Faster scanning sequences and new algorithms for data analysis made the visualization of, for example, connections instead of isolated spots possible, kindling a conceptual move from localization to networks. 25 Researchers realized that they could use similar technologies not only for bold reductionist claims, but also for visualizing interaction and hence for testing more complex hypotheses: If the technology served so well for "reducing" psychic functions and mental states to brain processes, it could also be used for objectifying hitherto problematic states such as, for example, psychogenic paralysis 26 or hallucination 27 as "real" brain phenomena. As I have argued elsewhere, brain research, together with the public debates surrounding it, should better be understood as a cultural phenomenon curating the mind-brain problem, keeping it alive and open, rather than as a process of scientific progress towards explaining mental phenomena according to the reigning materialist epistemology. 28 Around the year 2010, a similar transdisciplinary approach lead to the emergence of cultural neuroscience as the sub-discipline with its own conferences, jour- Culture and the brain were once thought of as mutually exclusive views on variation in behavior and were subjects of study divided by relatively strict divisions across the natural and social sciences. Although it is clear now that culture and social experience may readily shape brain function, this was not always the case.
[…] Progress in the emerging field of cultural neuroscience has been bolstered by accumulating evidence for neuroplasticity. 31 The brief reference to "neuroplasticity" sufficed as buzzword for explaining why formerly contradictory or at least adversary approaches should flourish hand in hand.
There was no need, apparently, for further justifications; it now seemed obvious that the brain was a cultural object, as it had previously been obvious that brains were biological products of the anonymous process of evolution.
Cultural neuroscience could thus be celebrated as offering a perfect mediation between hitherto disconnected approaches to human life. Or, as Shinobu Kitayama Cultural neuroscience can make important contributions to the study of culture by providing important insights about how 'deep' culture can go into the human brain. If nothing else, it would be very hard to maintain, with the currently available behavioral evidence alone, the position that culture is no more than a superficial overlay that may be best stripped out in the study of the human mind.
[…] Moreover, because the brain reflects culture, brain activation patterns can provide important information about the very characteristics of the cultures themselves that are compared. 32 Regardless of the celebratory prose, it should be noted how culture is not introduced here as an epistemic milieu nor conceptualized in any specific way, but just alluded to as phenomenon objectified by neuroimaging. In this example, cultural neuroscience shall connect relevant pieces of "information" from the two sides of the nature/culture divide without much concern for theoretical constraints, appropriate ways of mediation or the formatting effects of investigative technologies.
Exploring cultural specificities as brain-based phenomena, some authors reported differences in brain activation for religious denominations. 33 The typically western (and schematic) idea that a Christian would focus more actively and frequently on her "self", while a Buddhist would aim to "transgress the self", inspired studies that found different patterns for Chinese Christians compared to Chinese Buddhists, for example. 34  constructs. 35 Building on critical scholarship from within neuroscience, I've argued elsewhere that such studies, far from engaging in productive interdisciplinary dialogue, foreclose intercultural interaction and intellectual exchange by arriving at allegedly objective evidence that is ill-founded on highly problematic and un-reflected concepts. 36 Cultural neuroscience is in this regard a typical example and easy target for the type of critique brought forward by Vidal and Ortega that neuroscience expresses more of a creed and does not result from major scientific breakthroughs. With its shallowness, cultural neuroscience is a striking example of how neuro has become "uncomfortably protean". 37 Many of these studies are interdisciplinary by labeling, by declaring the approach to be so on basis of applying neuroimaging to a cultural phenomenon, with, in fact, no humanities scholars actively involved in the study design, data generation or the interpretation of results. Transdisciplinary cooperation is carried out here strictly according to a division of labor and of scientific credit, with the cultural experts restricted to the role of delivering useful classification systems for the diverse manifestations of human life, typically in form of objectifying tests scores, that are then investigated "scientifically" by means of the available neuroscience tools.
The peak of enthusiasm for cultural neuroscience, however, appears to have occurred some five years ago, at least according to the number of publications and reviews listed in the US National Library of Medicine. Cultural neuroscience has also become a target for scientific critique from within neuroscience, insisting on the scholarly specificity of humanities perspectives. 38  its cultural dominance by exerting transdisciplinary cooperation along such lines, it calls for "dissensus" as radical response to the often celebrated "consensus" on a brain-mind-culture continuum, as Cynthia Kraus has convincingly argued. 39 The vagueness of cultural neuroscience and its striking conceptual limitations shed some light on transdisciplinary cooperation as neuroscience rhetoric, lacking proper forms of scholarly cooperation and exchange.

Neurophenomenology, Loosely Speaking
Vague rhetoric is not limited to cultural neuroscience but finds its complements in neurophenomenology. In addition, neurophenomenology is an actors' term with a broad spectrum of meanings. Here, the equivalent to shallow conceptualizations of culture is a loose speaking of "phenomenology" without buying into the philosophy of that name. A telling example is a paper entitled "Wittgenstein's neurophenomenology", alluding to the famous philosopher, but not engaging with his philosophy: His work on the inner and the outer, the relation between language and sensation or perception, and on the embodied nature of emotion and its This philosophical fuzziness of "neurophenomenology" became possible on basis of the common use of the word "phenomenology", especially in medicine and clinical practice, simply for referring to "phenomena" without any philosophical intentions or methodological precision. According to this usage, "the phenomenology" of a particular condition, disease or case (like "the phenomenology of tics", for example), simply signifies its clinical appearance. In this rather loose understanding, "phenomenology" denotes the empirical appearance of something, across the entire spectrum from the individual case to the typical. 41 If the phenomenology of something is basically its appearance, "neurophenomenology" can be the condition of "a phenomenon" related to neurology or neuroscience and situated in the borderlands between appearance and experience. A proper discourse analysis could draw 41 Joseph Jankovic, and Stanley Fahn, "The phenomenology of tics," Movement Disorders 1, no. 1 (1986), 17-26. here from many similar titles, all published after the year 2000. These titles, papers and books testify by their mere existence to the reigning discourse without delivering much of what they claim to explain.
In its extreme form, "neurophenomenology" is little more but the name for an idiosyncratic gluing-together of private research interests with a self-made philosophy of mind and brain, as the following example demonstrates. In Neurophenomenology and Its Applications to Psychology, Susan Gordon shows surprising robustness in applying the term: Instead of providing a systematic introduction of the concept and of reviewing the relevance of the field for psychology, as one would expect from the title, she combines four papers by other authors (on neurophenomenologywhatever it is -in relation to emotion, to pedagogy, to meditation and to William James) with her private theory of "psychoneurointracrinology": This chapter introduces a psychoneurointracrine model of the embodied self and examines the interrelationship between psychological, neurological, and intracrinological processes forming a mind-brain continuum within the person.
Psycho (psychological) refers to constructs variously referred to as psyche, self, soul, mind, and consciousness. Neuro (neurological) refers to the composition and reactions within the nervous system. Intracrine (intracrinological) refers to the intracellular biosynthesis of steroids, the binding of receptors, and the formation of enzymes that catalyze the creation of hormones within the cell.
It is argued that self has neural correlates in the hypothalamic-pituitary-gonadal (HPG) and hypothalamic-pituitary-adrenal (HPA) axes of the body, which are responsible for enactive engagement and the development of meaning through their connections to the higher-order functions of the brain. 42 The author offers her own solution to the mind-brain problem, so long sought after, by a unifying theory based on an obvious mereological fallacy, infusing brain chemicals with mysterious "enactive" powers. Such philosophical vagueness of "neurophenomenology" points to an important aspect of the current style in relating between philosophy, neuroscience and the psy sciences, e.g. the combination of epistemically radically heterogeneous perspectives. Some studies seem to share sincere concerns, while others exhibit philosophical inconsistencies and "neurophenomenology" seems to serve its role as mere catchword covering up shortcomings. Others address directly the problems of mediating experimentally between psychic experiences and experimental observations. Because these trends all sail, in one way or another, under the umbrella term "neurophenomenology", they call for conceptual critique and a careful re-examination of phenomenology's aims in light of the new neuro.
The guilt for the fuzzy ambivalence of "neurophenomenology", however, does not fall exclusively on the want-to-be philosophers among the neuroscientists. The Oxford Handbook of Neuroethics seems to provide, at first glance, a good example for more comprehensive and interdisciplinary approaches also by actors from the camp of the humanists. The editors invited neuroscientist and NIH representative Alan Lashner for an introductory chapter on "Bridging neuroscience and society", for example. 43 On closer inspection, however, the volume turns out to follow strictly a hierarchy of knowledge, controlled and regulated entirely by neuroscience and ignoring the sociopolitical context of this research or the philosophical underpinnings of the knowledge thereby yielded. John-Dylan Haynes sets the tone for the following chapters when he opens by explaining the current state of brain reading, as the following chapters all start in the same manner by explaining some experimental findings as "neurobiological basis" for deducing some "neuroethical implications".

Neurophenomenology, Strictly Speaking
In a more specific understanding, neurophenomenology designates a field of study where "phenomenology" is linked to the philosophical program of this name and reflects how it could be mobilized for neuroscience. In this meaning, the term describes a specific intervention into brain research and cognitive science from philosophy. As first use of the term "neurophenomenology" counts a book with the subtitle 45 Suparna Choudhury, and Jan Slaby, "Introduction. Critical Neuroscience-Between Lifeworld and "Toward a neurophenomenology of consciousness" that discussed the shortcomings of the prevailing reductionism in cognitive science. 47 This points already to the context to be analyzed here, namely discussions on the structure of consciousness in relation to the nature of neuronal processes, but the book did not engage with phenomenology as a philosophical program. It was Francisco Varela who formulated the project of bringing phenomenology to cognitive science and to marrying the two to a new form of neuroscience under the name of "neurophenomenology".
Varela introduced neurophenomenology in 1996 as name for attempts to mediate between third-person observations and first-person accounts. The idea was to bring the full weight of phenomenology as philosophical exploration of introspective experiences into debates in cognitive science on the "hard problem" of qualia as lived experiences: The phenomenological approach starts from the irreducible nature of con-  Laughlin Jr., John McManus, Eugene G. D'Aquili, (New York: Columbia University Press, 1990). The subtitle provides evidence for the long history of the pragmatic understanding of "neurophenomenology" and thus demonstrates that a "neuro" prefix already functioned as stylish title well before the takeoff of neuro.
it becomes a mysterious riddle. Second, structural accounts provide constraints on empirical observations. 48 Compared to the widespread parlance of "neurophenomenology" described above, Varela's plea stands out by a series of remarkable specifications (to be discussed below) -and the question arises how the more recent work following under that label lives up to his ideas, now that neurophenomenology has become a branch of empirical neuroscience.
With the search for "meaningful bridges" between "matter and brain" on the one hand and "conscious experience" on the other, Varela seems to have anticipated today's rhetoric of cultural neuroscience mediating between brain function and social experience. But one would have to clarify immediately how his project focused explicitly on the conceptual conundrum which cultural neuroscience shunts by obfuscation. The shortcomings of the one-sided variants of transdisciplinary cooperation discussed above are exposed here right as starting point and would have been The study of mental phenomena is always that of an experiencing person. We claimed that cognitive science cannot escape this circulation, and must cultivate it instead. We explicitly draw from Asian traditions, Buddhism in particular, as living manifestations of an active, disciplined phenomenology. It seems that senses of awe and wonder come as close to human universals as could be imagined and if we look at long-standing philosophical discussions of such things, the result of that universality has been that we have gone outside of ourselves to explain or understand our senses of awe and wonder.
[…] And yet, that move has, until recently, taken us away from considering awe and wonder as phenomena worth understanding in their own right. […] The aim of this study was to explore what traditionally might be called the inner space of experience, while travelling in outer space.
[…] The study of the experience of those who have travelled to space avoids the temptation 54 Vital Models: The Making and Use of Models in the Brain Sciences, ed. Tara Mahfoud, Sam McLean, and Nikolas Rose, Progress in Brain Research 233 (2017), 2-226. to either reduce awe and wonder to mundane experience or explain it completely by reference to some internal processes caused be external stimuli. 55 Gallagher and colleagues report in this book on a complex research project for which they teamed up with scholars in linguistics, art history and hermeneutics on the one hand and experts in psychophysiology, neurophysiology, computer sciences and simulation studies on the other, for perfecting psychophysiological measurements related to experiences of awe and wonder as simulated in experiments with space travel. One might be tempted to laugh at the simplicity of the simulation, consisting in a room mimicking the interior of a space ship with an outlook through appropriately shaped "windows", where the appropriate film sequences of views through a space module upon planet earth and/or the moon and stars were provided on computer screens. However, the experiments with the makeshift space ship worked well enough to make the volunteers wonder and to reflect on their experiences, although nobody had left the surface of the earth, let alone gravity. And the experienced states of awe and wonder corresponded with specific changes in EEG recordings, although the subjects did nothing but look at the images of planet earth or stars. The experiments thus demonstrated the experimental testability of awe and wonder, two exquisitely human and cultural experiences.
And yet, the study on awe and wonder has little to offer beyond an amazing effort to mimicking space travel without going (and getting) there. The disappointment does not so much result from the obvious discrepancies between the simulation and the imagined real but from the rather frustratingly limited information in the psychophysiological data, demonstrating awe and wonder as bodily experiences wanted to connect the best of both worlds -but Varela had already seen that such a hope is in vain, if it ignores limitations and constraints as truly significant insights.
Perhaps neuroscience progresses better by failures than by breakthroughs.
Gallagher and his co-authors conceived of neurophenomenology, like Varela, as "non-reductionist cognitive science" that should start by critically evaluating methodology. Before embarking on space travel, Gallagher had teamed up with Dan Zahavi for positioning phenomenology as missing link between philosophy of mind and cognitive science, 56 and he had edited a handbook linking phenomenology with cognitive science. 57 Working out the details of awe and wonder as empirical correlations, however, did not arrive at experiences as empirically explicable qualities, so it seems; the attempt to explore consciousness in terms of neuro determinants was destined to failure, calling for further experimental refinements. 58 In consequence, Gallagher started most recently to "rethink the mind" by an "enactivist intervention", conceiving of mind as radically social, interactive process and emphasizing the "enactive" concept of mind that Varela (together with Evan Thompson and Eleanor Rosch) had developed in the 1990s. 59 In light of this line of empirical research and philosophical reflection, neurophenomenological research appears as perfect example for research as a way of curating the mind-brain problem, developing ever more refined methodological considerations for arriving at even more sophisticated experimental arrangements -and for safeguarding experiences from explanation. Apparently, neurophenomenology functions best as a critical program insisting on subjective experience. 56 Shaun Gallagher, and Dan Zahavi, The phenomenological mind: an introduction to philosophy of mind and cognitive science (London: Routledge, 2008). 57 Handbook of phenomenology and cognitive science, ed. Shaun Gallagher, and Daniel Schmicking, (Berlin: Springer, 2009). Of the 33 chapters, however, just two had "neurophenomenology" in their title; apparently, the neuro had not yet been assigned the role of master concept. 58 A good example of this tendency provide Patricia Bockelman, Lauren Reinerman-Jones and Shaun Neurophenomenology reported fascinating results, and the actors secured some turf by propagating its message. Along this trajectory, Varela and his allies in neurophenomenology moved away from narrowly focusing on the hard problem and explored, for example, first-person accounts of visual perception but encountered new limitations as the experimental subjects had to be trained in phenomenology. 60 And yet the succinctness with which Varela determined neurophenomenology to bring constraints to the fore still stands out as major insight, towering over the positive data from further studies. A specific productivity of neurophenomenology appears to rest on the negative, e.g. as critique of shortcomings and as skepticism towards overblown interpretations of results.

Concluding by Performing Critique
Among the more surprising turns in recent debates on neuroscience is a paper critiquing Critical Neuroscience as armchair philosophy indulging arrogantly in ignorance vis-à-vis the true significance of rigorous experimental approaches. Andreas Roepstorff, one of the authors in Gallagher's handbook and a leading figure in transdisciplinary approaches to neuroscience, argued that Critical Neuroscience misses opportunities for "enacting" its critique if it insists on social context regardless of the specificities of a particular experiment -which may yield insights precisely by shunning context. Taking the example of an experiment demonstrating the superiority of collaboration over individual work in specific situations, the authors concluded that in this case precisely the "formal and context-denying conventions of neuroscientific experimentation" had yielded significant evidence in form of robust data.
Instead of reading Roepstorff's exchange with Critical Neuroscience as self-opinionated dispute between opposing paradigms, the paper can be taken as an intervention. It performed an argument by pointing to the emptiness of the repeated 60 Antoine Lutz, Jean-Philippe Lachaux, Jacques Martinerie, and Francisco J. Varela, "Guiding the study of brain dynamics by using first-person data: Synchrony patterns correlate with ongoing conscious states during a simple visual task," PNAS -Proceedings of the National Academy of Sciences of the United States of America 99, no. 3 (2002), 1586-1591. invocation of context if that misses the rigor and force of what a "tightly-bound neuroscientific experiment can actually do." 61 Read in this way, the paper confirms some of the observations made here, although it seems to contradict them at first glance.
As performative act, the paper pushes a highly reflexive argument contextualizing specific methodological approaches and their effects. It thus relies on much more than it ostensibly advertises and is thus indicative of the trend to transdisciplinary methods instead of boldly reductionist approaches. And like Varela's insistence on limitations, its strength relies in a critical, if not frankly negative mode, engaging in an adversarial mode of collaboration: Critical Neuroscience is critiqued here not for safeguarding context-denying experimentation but for opening a space of new possibilities. From the dispute does not follow that philosophical and sociopolitical reflections preempt empirical work; on the contrary, Roepstorff and his co-authors engaged in it.
Performing critique can also occur as reflexive practice by repeating experiments.
When John Dylan Haines repeated Benjamin Libet's experiments on the neuronal timing of mental decisions in around 2000, i.e. at the peak of reductionist claims and the neuro hype, he claimed that he was able to show that subjectively "free" decisions are encoded by brain activity up to ten seconds before awareness. 62 At that historical moment, Haynes' experiments seemed to confirm that conscious decision making is nothing but a nice illusion, and he did much to foster this interpretation. Some years later, however, and in the slightly changed climate of cultural awareness and transdisciplinary cooperation, he and his team started to wonder whether they could also test Libet's more speculative hypothesis of a mental "veto", the intellectual ability to stop an action already encoded. And again they succeeded. The team now showed that subjects were able to win a "duel" against a brain-computer interface predicting their brain's decisions. 63 Whereas the first paper "proved" human beings to be neuronally predetermined machines, the second demonstrated that the very same human beings could outwit such machines.
There is not much sense in arguing one of these experiments to be superior to the other or to accuse Haynes of simply hopping on the bandwagon of paradigm changes. Varela's conceptualization of neurophenomenology, Roepstorff's critique of Critical Neuroscience and Haynes' repetitive experiments that science is not about determining an outside reality because science is part and parcel of this reality -just like the society and culture in which it takes place. Changing paradigms have multiple reasons. Scientific advances and technological developments do play a certain role, but others result from the concerted efforts of critical scholars, the wider public or simply the changing contour of general concerns. Haynes' most recent feedback experiments with brain-computer interfaces returns to the performative arts from the 1960s, when composers like Alvin Lucier created paradoxical and self-contradictory interventions like his Music for Solo Performer. In this piece of creative research, the artist on stage hooked himself up to an EEG device, picking up his brain signals and transforming regular and powerful brain waves like an alpha rhythm into electric signals driving drums. The condition necessary for generating an alpha rhythm, however, did not match a situation of attention and awareness like being on stage.
On the contrary, brains generate alpha waves during states of relaxation and disconnection from sensorial input. -Exactly this contradictory constellation was the challenge that Lucier turned with his performance into a famous piece of music. 64 Alpha waves were generated by the performer as long as he relaxed and disengaged from any specific thoughts. Since this was a public performance on stage with the task to generate sound, any relaxation was difficult; by listening to some sound already generated -if the relaxation had been successful so far -the performer would have inevitably concentrated and thus extinguished the neuronal source of the sound and hence the music. At the core of the piece was thus a contradictory constellation of self, brain, and machine. The performance revolved around the very concept of a contradictory constellation, turning precisely the incompatible interferences between a self, a brain, and a machine into soundscape; just like Haynes would connect the self with a brain-computer interface several decades later. The performance accessed a zone of uncertainty that Haynes explored scientifically. "Self or brain?" would obviously be a misplaced question in such an arrangement that yielded its aesthetic and epistemic insights from exploring the dead ends of neurophysiology. The performance from the 1960s and the experiment some fifty years later demonstrate the contradictory inconsistencies of attempts to outwit the brain and/or self by means of advanced scientific knowledge.
Lucier performed an "enactive" intervention -and he did so many years before brain research arrived there. His performance had turned the stalemate that Haynes explored in the laboratory into a space for unexpected aesthetic experiences. Back then, there was no "neuro" in the sense of shorthand for a discursive formation and an alliance of powerful research institutions, but cybernetics and control dominated the discursive space of brain research -including many of the psy sciences before Foucault set in. Lucier performed the experimental thought style of the 1960s, while Haynes embodied the rigor of the Decade of the Brain, before he succumbed to the fascination of machines that Lucier had already celebrated. Feedback, cooperation and critique operate the better the closer they articulate; their articulation, however, appears to change over time, with the more fundamental alignments becoming visible only at historical distance. Haynes' turning from reductionism to competitive alliance of self and machine repeated artistic research form the 1960s and testified to some of the fundamental insights by the neurophenomenology of the 1990s without buying into them. Today, neuro may dominate "our thought", but it does not prevail as monolithic framework with a single overarching agenda. Neuro is rather the collective effect of thousands of researchers working with different tools on many different questions. Precisely because of the pervasiveness of brain-based explanations and neuro arguments, any analysis of their dominance should carefully evaluate the specific articulation of psy science with philosophy in the neuro turn. "Culturalizing" neuroscience may function like a superficial amalgamate and new directions like cultural neuroscience should be carefully scrutinized as branches of neuroscientific research. But such critique is itself part of the game, participating at performing neuroscience and shaping its more questionable or not-so-problematic sociopolitical effects. Critical Neuroscience has certainly helped to highlight some problematic forms of neuroscience, whether it has also contributed to new problematic forms remains to be determined. But critique should continue to engage with the tensions between the psy sciences, philosophy and neuroscience for letting the human sciences thrive.
