What brain wave states are associated with hypnosis? What brain wave states are most correlated with deep hypnosis?
Hypnotic states are associated with increased theta wave activity. Hypnotically susceptible participants also exhibit hemispheric beta wave asymmetry, but non-susceptible participants do not (Sabourin, Cutcomb, Crawford and Pribram, 1990).
