“…Earlier, we showed that, in group 2 patients (a high level of anxiety), the largest coherence changes were also revealed in the β and θ bands [23]. When studying the emotional reaction to the words that were pleasant, neutral, or unpleasant to the subject, with the EEG and positron emission tomogram (PET) recorded simultaneously, Herrington et al revealed changes in the dorsolateral prefrontal cortex [24].…”

“…It follows from the aforementioned that a broad spectrum of the patients' autonomic visceral com plaints is reflected in wider changes in the cross corre lations in the cerebral cortex in the patients of this group, which suggests more serious structural and func tional changes at the cortical and cortical-subcortical levels. Earlier, when performing the factor analysis of intracerebral EEG integration, we showed dysfunction in the activity of the associative thalamo cortical sys tems responsible for the organization of regulated sys temic interactions of the cortical bioelectrical activity in the frontooccipital direction of both hemispheres [23]. It is possible that precisely this dysfunction leads in depression to the mismatch of the activity of the ante rior and posterior hemispheric regions indicated by Strelets [33], who suggested that a "transverse func tional block" of interactions between the frontal and occipital hemispheric divisions could be formed in depression [34].…”

At present, there is no doubt that the cerebral cortex continuously receives information about the state of the internal organs and visceral systems and, being the cen tral coordinating organ, ensures normal functioning of the psychoemotional and autonomic sphere in the interaction with the subcortical structures. The basic assumptions about the cortical representation of the internal organs and autonomic cortical centers, as well as about their functional interrelations, were formulated by V.N. Chernigovskii and his school on the basis of vast experimental material. According to Chernigovskii, "what is most essential is the understanding of how and via which pathways the relation and interaction between the representation of afferent and efferent visceral structures at the level of the cerebral cortex occurs …" [1]. These assumptions were confirmed and developed in further investigations of Russian and foreign scien tists [2][3][4][5].Under pathological conditions, disorders in the cerebral central integrative systems ensuring the normal activity of individual organs and visceral systems on the whole are the main cause of psychoemotional auto nomic visceral complaints. However, the mechanisms of these disorders have not been investigated in detail. In our opinion, neurotic depression, in which a wide spec trum of autonomic visceral disorders is revealed in addi tion to affective disorders, is a convenient model for studying these mechanisms. These pathological changes are of functional character and, with modern diagnostic methods, do not reveal the organic basis of changes in the brain or other internal organs.The aim of this work was to study the spatial struc ture of the systemic organization of the brain bioelectri cal activity and the autonomic profile in patients with neurotic depression, compared to the normal state, with subsequent comparison and revelation of relation ships between the neurophysiological and autonomic parameters.Abstract-Studies were conducted with the participation of 20 patients with different classical variants of neurotic depression. The spatial organization of the bioelectrical activity of the brain was studied with the method of cross correlation and coherent analysis. The autonomic-visceral state was assessed by the results of the auricular cryoreflex test (measurement of the cold sensibility of auricular points). The clinical picture of neurotic depression was shown to be reflected in the structure of the EEG spatial organization, which is modified depending on the degree of neurotic depression and the concomitant anxiety and asthenic syn dromes. In the group with depressive syndrome without concomitant asthenic or anxiety manifestations, most changes were revealed in the right frontotemporal-left posterotemporal region. A cross correlation and coherence decrease in the frontotemporal regions of both hemispheres and markedly increased cross corre lations in the right posterotemporal region were revealed in the depression + associated anxiety group. In the group where the depress...

The review presents information on the somatovegetative interaction of blood circulation and respiration from the point of view of the views of Professor Yu.P. Pushkarev. Data are presented that speak of the complexity and complexity of the problem of homeostasis and adaptation, the unresolved many issues that are important for understanding the stability of the internal environment of the body and establishing the limits of the norm. It has been shown that within the neurohumoral system of the body, the interaction of various components of functional systems is constantly carried out, ensuring the conjugation of respiration and blood circulation with the formation of intersystem links. Some aspects of the formation of functions in animals and humans in postnatal ontogenesis are considered. It is emphasized that homeostasis is an internal balance of indicators in the body, but its values are constantly changing due to the center-peripheral integration of functions. It was emphasized that the process of achieving a beneficial adaptive result is characterized by the asymmetry of physiological indicators, and the intersystem interaction ensures the balancing of homeostasis constants in terms of adaptation to environmental conditions. It has been shown that over-threshold environmental influences and homeostasis parameters shift in the body, compensatory-adaptive reactions occur, aimed at maintaining a certain level of stationary state, eliminating or limiting the effect of the harmful factor and optimizing the interaction of the organism and the environment due to the formation of intersystem links. Analyzed the pathophysiological mechanisms of changes in function in certain diseases and stress effects. It is shown that the further study of the somatovegetative interaction in the context of the ideas of Yu.P. Pushkarev will allow revealing the true mechanisms of synchronization of functions in the organism of animals and humans in order to understand its existence as an independent self-regulating system.
