Фотопериодическая система мозга и её участие в механизмах адаптации к острой гипоксии

Abstract

The neurofunctional system, which receives a photoperiod, is a photoperiodic brain system. As a part of chronoperiodic system of organism it is involved in perception and transfer of information about the main external Zeitgeber to the peripheral tissues. Such role of photoperiod ic system allows it not only synchronize the chronorhythms of different somatic and visceral functions, but also realize the coordination and the modulation of adaptation mechanisms to the stressors influence such as an acute hypoxia. It has been esta blished that the pineal gland played one of the most important roles in the whole system of the antihypoxic defence of the organism, realizing such defence according to the duration of the photoperi od by means of the action of its hormone s of indole (melatonin) and peptide nature.
