[The role of the central nervous system in controlling hibernation]

Abstract

Bibliographic and original experimental data related to the problem of the role of central nervous system in controlling hibernation are analyzed. It is shown that limbic structures (septal zone, hippocamp, hypothalamus) are of great significance. Taking into consideration the key role of medial septum as a generator of hippocampal theta-rhythm, the elevated excitability of septal neurones in brain slices obtained from hibernating animals and other experimental data, a conclusion is drawn about the role of medial septal nuclear complex as the forebrain "watch point" in hibernation. The significance of thyrotropin-releasing hormone in controlling the waking/hibernation cycle is discussed.
