Distribution levels of coherence relations of EEG nucleus rapher and locus coeruleus with the strucures of visual system of brain

Abstract

Studies pertaining to the mechanisms and patterns of participation of different neuromodulatory centres of MA-ergic nature (n.raphe, locus coeruleus) in the regulation of neural processes in recent years are of particular importance when addressing the issues of optimization of neural processes both in normal and with different kinds of functional disorders. However, some aspects of the problem are not well understood. In particular, it is not the features of participating neuromodulatory centres in the organization of the electrical activity of different functional associations of the brain. The present work is devoted to analyse the distribution of coherent relations of the EEG neuromodulatory centres with the central structures of the visual system of brain. The results of the experiments indicated that 5-HT-ergic system characterized by a more significant correlation with the structures of visual analyzer than for NA-alicesme system of the brain. Thus the highest values of coherence potentials of nuclear rapher correspond to the theta and alpha ranges of the EEG.
