The influence of melatonin on the ultramicroscopic state of neurons of the lateral preoptic nucleus of the hypothalamus during light stimulation

Abstract

Currently, the number of elderly people in the world is increasing. Among the problems that are characteristic of this age group is a violation of the quality and/or duration of sleep, which can affect the development of pathological sleep disorders and the general state of health. Sleep is an extremely complex genetically determined cyclic process that is regulated by homeostatic and circadian components with the participation of various neural structures, among which the lateral preoptic nucleus (LPO) of the hypothalamus plays a key role.
