The aim of the study was to reveal a probable structural-functional basis of emotional self-regulation processes within the framework of cortex--basal ganglia interaction using on-line computer analysis of the EEG. The tested subjects were unable to overcome the emotional stress increasing in the process of decision making under conditions of high responsibility for the results of task solving. Striving to hold their social positions these subjects created a stable psychological set to keep their high responsibility and resist the relaxation tendency. Such a set facilitated the acceptance of the task for volitional effort to resist fear controlled by a biofeedback displayed in skin galvanic reaction.

Functional rearrangements in the human brain during emotional self-regulation with biological feedback.

The concept that functional psychopathology producing phobic syndromes is mediated by a specific deficiency in the integrative activity of the brain as a loss or partial limitation of the ability to recognize subjective experiences was used to develop a special method for mobilizing the selective attention of patients to the time course of subjective states. The fact of recognition of a state was demonstrated by the patient's ability to reproduce it by achieving specific parameters in a biological feedback test based on skin electrical responses. Success was positively reinforced by avoidance of an anxiously expected electrical stimulus. After successful training, patients could spontaneously adaptively correct their general daily behavior. Computer analysis of EEG traces revealed the specific structural-functional features of various states provoked during training.

By means of a special technique, mobilising of a subject's selective attention upon the dynamics of the subjective sphere states, was reached. An involved biofeedback was positively reinforced by avoidance of an expected electric stimulus. The subjects revealed occurrence of an adaptive correction of their general behaviour. The EEG computer analysis manifested a specifics of structural-functional maintenance of different states evoked in the training process.

Restoration of regulation of the feeding behaviour after subdiaphragmatic vagotomy in dogs occurs despite of the destruction of nervous fibres within the nn. vagi and the death of their neurons in medullary nuclei. The finding is regarded as a result of formation of a new dominant state in the central nervous system.

On the model of biofeedback connection by the given parameters of the EEG alpha-rhythm the dynamics of bioelectrical and vegetative characteristics and correlative connections between them were compared in the pairs of mono- and dizygotic twins. More likeness in the dynamics of the studied parameters was found in the pairs of genetically identical monozygotic twins. There was a maximum increase of the objective similarity characteristics in the moment of activity realization, judging by the change of alpha-rhythm parameters. The obtained results testify to genetic determination of individual specific styles in organization of complex integrative processes of the higher nervous activity.

Trace processes due to presentation of visual nonverbal information, and the dynamics of the bioelectrical parameter (mean level of asymmetry of EEG-waves) were studies in 32 pairs of monozygote and 38 pairs of dizygote twins with twins method. Statistical processing of the data revealed a significant effect of genetic factors on the formation of individual variability of the characteristics of trace processes in humans. The results obtained showed that with increased functional load the intrapair similarity of trace reactions increased in monozygote twins and did not change or decrease in dizygote twins and in unrelated pairs. This fact is interpreted at a dependence of appearance of geneticly determined neurophysiological characteristics on the level of functional activity of the nervous system.
