title: [Hypnotic effect in individuals with varying degree of suggestibility].
abstract: The paper presents the results of the investigation concerning time and space organization of brain cortex electric activity and peculiarities of autonomic regulation of cardiac functions in 19 healthy individuals, which had a pronounced intention to counteract of hypnotic influence. Taking into consideration the reactions to hypnosis, these individuals were divided into three groups: predisposed to hypnotic suggestion, sensitive (intermediate group) and resistant to hypnotic suggestion. In predisposed individuals there were more pronounced sympathetic influences on cardiac functions and less spectral power of all EEG rhythms, except beta 2-rhythm. In individuals resistant to hypnotic suggestion there was more pronounced alpha-rhythm in brain cortex, while sympathetic influences on the cardiac functions were not so pronounced. All individuals reacted to hypnotic suggestion by a decreasing of the representation of alpha-rhythm and by diminishing initial interhemispheric asymmetry. However, a share of beta-rhythm was increased in predisposed individuals and of theta-rhythm in resistant individuals. In posthypnotic state in resistant persons the correlations of initial EEG rhythms were completely recovered, while in the individuals from the other groups a recovery was observed only in separate EEG frequencies.
