EEG mapping including patients with normal and altered states of hypnotic consciousness under the parameter of...

In 1985 I first reported my observations of stimuli-synchronized changes of EEG spectra occurring in 25 hypnotized patients. Electroencephalographic leads recorded separately for the left and right brain showed a switch of electrical activities from the left to the right hemisphere in right-handed persons. In the following study we changed the experimental conditions, using an EEG brain mapping method promising even more reliable information and guaranteeing the actual state of hypnosis by extending the analysis to the state of posthypnosis.
