After a hypnotic induction, people who are highly or moderately hypnotizable often report spontaneous changes in consciousness, but few studies have controlled for the demands of specific suggestions or examined the brain activity underlying these experiences. In a neurophenomenological study of 37 individuals with high, medium, and low hypnotizability, participants reported their depth and spontaneous experiences at baseline, after induction, and after rest periods, while EEG measured brain activity. Perceived hypnotic depth increased substantially after induction, especially among highly and moderately hypnotizable individuals, but remained almost unchanged among those low in hypnotizability.
