Autonomic responses to emotional linguistic stimuli and amplitude of low-frequency fluctuations predict outcome after severe brain injury
2020, NeuroImage: ClinicalCitation Excerpt :Furthermore, no available studies reported a follow-up of the patients’ functional outcomes after the initial assessment. For example, in the study by Daltrozzo and colleagues (2010), event-related SCR associated with the presentation of emotional and non-emotional sounds were collected in a sample of 13 low-responsive (minGCS = 4, maxGCS = 6) acute (mean days from brain damage = 3.9) patients. In this sample, as in the healthy control group, a significant SCR effect was detected in the emotional vs. neutral sound condition.
Physiological feelings
2019, Neuroscience and Biobehavioral ReviewsCitation Excerpt :In a recent study, a patient diagnosed with an unresponsive wakefulness syndrome exhibited intact emotional responses to jokes as assessed by recordings of facial electromyography (Fiacconi and Owen, 2016). In another study, post-comatose patients showed a larger skin conductance response to auditory emotional stimuli as compared to neutral sounds (Daltrozzo et al., 2010). Similarly, in one patient who received central thalamic deep brain stimulation, modulations of oscillatory thalamic activity were observed in response to the voices of her children, which suggest an involvement of the central thalamus in processing emotional information (Wojtecki et al., 2014).
Using facial electromyography to detect preserved emotional processing in disorders of consciousness: A proof-of-principle study
2016, Clinical NeurophysiologyCitation Excerpt :Therefore, evidence that VS patients can in fact exhibit changes in autonomic and/or skeletal muscle activity in response to emotional stimuli would suggest that such measures may constitute a feasible bedside methodology for assessing emotional functioning in DOC, with the potential to detect covert awareness in some of these patients. Some previous support for this possibility was reported in a recent study in coma patients (Daltrozzo et al., 2010), in which it was found that such patients demonstrated a larger skin conductance response to auditorily presented emotional stimuli, and that this differential response was positively related to behavioural indices of coma recovery. While this finding is certainly consistent with the present results, it does not directly address conscious emotional functioning in VS. Moreover, measures of overall autonomic arousal (i.e., skin conductance) provide little information on the valence of emotional response, and can be driven by cognitive as well as emotional factors (Dawson et al., 2000).
Methods for Measuring Seizure Frequency and Severity
2016, Neurologic ClinicsCitation Excerpt :The EDR, mediated by sympathetic cholinergic fibers,40 reflects emotional state and autonomic nervous system activity.41 Measurement of EDR has been used in management of psychiatric problems,42 stress,43 electroconvulsive therapy,44 head trauma,45 coma,46 and several other conditions. Seizures are associated with increased autonomic activity.47
Continuous electrodermal activity as a potential novel neurophysiological biomarker of prognosis after cardiac arrest - A pilot study
2015, ResuscitationCitation Excerpt :This may be explained by sedation and analgesia effects, and the small number of patients (although there was a nonsignificant trend for this association). However, our isolated stimulations were possibly insufficient; previous EDR assessment after stimulation used more intense and longer stimulation and were obtained after conditioning.8,17 Thus, stimuli during nursing care, for example, were probably more prolonged and potent in enhancing EDRs in this setting.
