Potential production of Hughlings Jackson's "parasitic consciousness" by physiologically-patterned weak transcerebral magnetic fields: QEEG and source localization
2013, Epilepsy and BehaviorCitation Excerpt :Microsoft Windows, because of the background software operations and processes, can disrupt the point durations. Accurate and precise point durations are essential for producing the sensed presence [54,55]. Similar “temporal sensing” sensitivity for cells has been shown for frequency-modulated weak magnetic fields [56].
Neuroimaging and EEG-based explorations of cerebral substrates for suprapentasensory perception: A critical appraisal of recent experimental literature
2011, Psychiatry Research - NeuroimagingCitation Excerpt :Given that the application of TMS may cause subjects to become more suggestible (Booth et al., 2005), sensitive individuals may have picked up on experimental cues if the protocol was not performed in a double blind and otherwise rigorous manner. Since then, St-Pierre and Persinger (2006) have asserted that their past 19 experiments demonstrating effects of TMS have been performed with double blind conditions and that, instead, the discrepancy in results with Granqvist's group may be attributed to the kind of software used for generating magnetic fields (Persinger and Koren, 2005). However, it is not clearly specified just what the double-blinding procedures were, or how they were carried out.
The "Haunt" project: An attempt to build a "haunted" room by manipulating complex electromagnetic fields and infrasound
2009, CortexCitation Excerpt :They found no evidence that magnetic fields induced sensed presence, mystical, or other somatosensory experiences, but personality measures such as absorption, TLS scores, and orientation towards a new-age lifestyle did predict the occurrence of such experiences. They therefore argued that the effects previously reported by Persinger (1985, 2001), Persinger and Cameron (1986), Persinger and Koren (2001, 2005), Persinger et al. (2000, 2001) may well be nothing more than the effects of suggestibility manifesting themselves in experiments with inadequate use of double-blind procedures. Persinger and Koren (2005) have robustly rejected such criticism, claiming that their work does make use of adequate double-blind procedures and pointing out what they felt were methodological problems with Granqvist et al.'s replication attempt.
