Hypnosis

James Harrison presents his proposed account of hypnosis as mental foraging, relating changes in attention and internal state to memory and prediction. The conversation explores interoception, engagement with the external world and memory reconsolidation as possible ways to explain hypnotic experience.

Hypnosis is a natural psychophysiological state of consciousness characterized by selective attention and elevated responsiveness to suggestions aimed at modifying perception and behavior. Induction of hypnosis typically leads to phenomenological changes, including feeling of mental absorption, dissociation, and alterations of agentivity. In investigating associated brain mechanisms, researchers have focused primarily on perceptual-cognitive suggestions. Yet, ideo-motor responses to suggestions, like limb rigidity, provide a relevant opportunity to examine behavioral responses dissociated from

…of consciousness (NSCs) induced by hypnosis and bilateral alternating stimulations (BAS) as used in EMDR and the depth of these states. The neurophysiological processes underlying these states are investigated by measuring power spectral density (PSD) in frequency bands of the EEG signal and the deepness of NSC is assessed through visual analog scales on intensity, absorption, dissociation and immersion during memory recall. 25 healthy participants were included in the study. Each participant w
