Hypothalamic control of torpor and hibernation.

The article discusses the physiological process of torpor and hibernation in endothermic animals, including mice. Torpor is a hypoactive metabolic state that animals enter during periods of low temperatures and food scarcity to conserve energy. The central nervous system, particularly the hypothalamus, plays a crucial role in regulating torpor. The article presents recent findings on the neural circuits involved in torpor regulation, specifically focusing on the antero-preoptic area, medial preoptic area, and dorsomedial hypothalamus. The article also highlights the need for further research to understand the mechanisms underlying torpor and hibernation in different animal species, including humans. [Extracted from the article]
