Neurophysiological Studies in Hypnosis (Contingent Negative Variations)
Cerebral psychosomatics (study of the brain as the target organ following psychological events) is a most important area. Its progress can lead, in particular, to the disappearance of the psychogenesis versus organogenesis controversies (or environment versus heredity) which have been going on interminably in psychiatry. So far it had been difficult to show any neurophysiological changes under hypnosis (e.g., in EEG or evoked potentials). The technique of event related slow potentials (ERSP), developed in the past eighteen years, seems much more promising, in particular the contingent negative variation (CNV) and the post-imperative negative variation (PINV).
