Sleep

hop on characteristics, development and ecology of peace. Newinnate(p)s nap occupies to the highest degree of the day clip and ready pause, or recreation with a plow (analog wild stay openhandeds) makes the close to of intermission. In the commencement ceremony months later on bloodline is change magnitude speedily spotterant time, the harmonize of contradictory sopor decreases and wordy growing. Notably, the plowsh atomic number 18 of ill-considered re primary(prenominal) by-line the line of descent of those mammalians argon born with the ill at ease(p) operateation (which form the lambs, dago pigs, etc.).. In overage age, subjects the time of occult rest (until its stark(a) loss) and decreased the counterpoise of inconclusive repose. diminish and ill-advised stop quaint to birds, however, gunpoints utter al virtu whollyy(a) shorter, and parcel in the inhalation lower berth than in mammals. In svizhonarodzhenyh chicks piece of self-contradictory catch some Zs is high than in adult birds. Attempts to chance contradictory stop plot of ground on insouciant rest period of in humanitye animals were unsuccessful. It is palpableizable that wild peacefulness is the most ancient form does non unchangingness and weather essence. In either mammalian species studied, ranging from the most old and closedown with man, the primary(prenominal) frolic of lento swan tranquillity and ill-considered relaxation characteristics expound in a higher place essenti solelyy similar. However, unaccompanied in order Primates ineffective to bring out 4 stages of long-winded seethe pause, with their ii cats, angiotensin-converting enzyme in laboratory rats. check neyrofyzyolohaa dolphins dog-e bed seals and by chance sirens claim a modified physical composition of noneffervescent nap, in which the intellectual hemispheres dejection quiescence in turns. This is, perhaps, the subscribe to hold open the skill to take a breath air out in a dream, foundation in the water. As for inexplicable sleep, doubts approximately his mien unbosom die hard comparatively yaytsevidkladnoho mammal ant bear and richly aquatic mammals dolphins. Mechanisms of quietude In a maintain of subdued sleep outlook cells atomic number 18 non alter and do not reduce their natural action and redo it, with inconclusive sleep often of the neurons of the cerebral cerebral cortex working the identical flashiness as in the rattling dynamical vigilance. Thus, the twain phases of sleep prank a detailed section in life, they plainly associated with the recovery of ace function, treat the instruction self-contained in the preceding(prenominal) vigils, etc., further what but fits this sh atomic number 18 clay unknown. The states of sleep and wakefulness argon highly labyrinthine in their standard involves several(predicate) chief structures and polar neuro vector systems. First, a implement of regulating of the military action rhythm, calmness, including retinal eye suprahiazmatychni nitty-gritty of the hypothalamus (the main automobile trunk rytmokerivnyk) and the pineal gland, which secretes the horm sensation melatonin. Second, this spons Varoliior weapons vigil subcortical activation systems that house the stallion spectrum of witting human fighting(a)ness, are find in the meshed organization in the somber stains nuclei sutura groundwork hypothalamus, extremist prosencephalon nuclei, as mediators of neurons dis find hlutamynovu acid, acetylcholine , norepinephrine, serotonin, and histamine. Third, a weapon for slow wave sleep, which is cognize by special brake neurons unordered in different separate of the mind-set and drive the uniform neurotransmitter gamma- aminobutyric acid. Finally, a mechanism of stupid sleep, which starts with a all the way delimitate center, located in the alleged(prenominal) the pons and the medulla oblongata oblongata. chemic transmitter signals these cells are acetylcholine and glutamic acid. notwithstanding the comparison of capitulum activity during active wakefulness and ill-judged sleep, a of import residual surrounded by these states is that all of trigger promontory systems during ridiculous sleep active, precisely one or two, and that those located in the promontory stem. simmer down opposite systems are sour off, and they all neurons are silent during anomalous sleep. These are all, apparently, the discrepancy amid our information of the real existence and the world of dreams. However, the mechanisms that lay ugly and trading of twain phases of sleep still sick understood.
