The dynamics of the spatial synchronization of brain biopotentials in conditions of intense attention in the hypnotic state.

Twelve mentally healthy women aged 21-38 years were studied in the state of consciousness and hypnosis. The main study method was electroencephalography with assessment of the spatial synchronization of brain biopotentials (SSBP). Suggestion of high-intensity attention delivered to subjects in the hypnotic state was found to lead to significant reorganization of SSBP, with increases in SSBP between both occipital areas, the right temporal area, and other parts of the brain. The dynamics of brain SSBP in intense attention were opposite in the hypnotic and conscious states, which appears to result from the temporary exclusion in the hypnotic state of the functions of the frontal areas of the cortex responsible for conscious control and regulation of ongoing activity.
