This study employs eLORETA source localization of EEG recorded during a New-Old Face recognition paradigm to demonstrate enhanced upper alpha activity in cortical regions supporting the retrieval of face information during hypnotically suggested face amnesia but not during normal forgetting. We demonstrate enhanced upper-alpha functional connectivity in this network of regions supporting face recognition during hypnotic amnesia but not during normal forgetting. These findings extend earlier studies which indicate a functional role for the alpha rhythm in gating the availability and influence of specific forms of information during different types of human cognition. These results provide the first direct evidence for a mechanism by which selective forms of information processing may be inhibited in response to specific hypnotic suggestions that is for ‘negative’ hypnotic hallucinations. This provides a model not only for hypnotic dissociation but for other forms of psychogenic dissociation, guided by response expectancies, which occur in many conditions outside of the hypnotic context.
