[«Selfish brain» theory: modern concept and practical use. (Literature review)].

Abstract

In the early 20^th century, the term «selfish brain» appeared in scientific literature, around which theory was formed, finding its proof in the work of doctors and scientists. The basic principle of the theory is that the superior hierarchy of the brain, whose needs are prioritized, results in the primary satisfaction of one's own needs, often to the detriment of the functioning of other organs and systems. The origins of the theory of «selfish brain», according to researchers, lie in the work of neurosurgery pioneer Harvey Cushing, who discovered a reflex named after him and consisting in increasing arterial pressure at high intracranial pressure. Later, the field of action of this phenomenon was expanded by specialists who showed that an increase in arterial pressure can occur not only in critical situations and arise not only at high intracranial pressure, but also as a result of hypoxia of the brain. It was also found that the remodeling of intracranial vessels in hypertensive disease may be not only a consequence, but also a cause. Currently, similar patterns have been established in relation to other processes - exchange, immune and others. It was found that the priority of brain energy needs in different situations can affect insulin resistance and glucose tolerance. These effects can be realized through various mechanisms, but the advantage is through vegetative (autonomous) nervous system, mainly through sympathetic link, and also through simulation of the functioning of parasympathetic link. It is known that there is currently a rapidly increasing number of pathologies associated with degenerative-dystrophic processes of the spine, and other factors that disrupt the blood flow in the vertex-basilar zone of the Willis circle, Correction of these processes with the help of a set of manual techniques and physical methods (A. Yu. Shishonin's method with correction of aerobic-anaerobic energy balance in the reflex zones of the brain stem) Can have a good effect on the treatment of hypertensive disease and other chronic non-communicable diseases.
