Hypothalamic survival circuits related to social and predatory defenses and their interactions with metabolic control, reproductive behaviors and memory systems

Publication date: December 2018 Source:Current Opinion in Behavioral Sciences, Volume 24 Author(s): Newton Sabino Canteras The hypothalamus may be viewed as the central piece of the survival circuits and is responsible for organizing endocrine, autonomic and behavioral responses to guarantee the survival of both the individual and the species. The hypothalamus is largely known to control the three basic classes of behavior required for animal survival, namely, ingestive, defensive, and reproductive behaviors. Over the years, a great deal has been learned regarding the hypothalamic circuits organizing these classes of behavior. In this review, we will focus on hypothalamic circuits involved in organizing anti-predatory and social defenses, noting putative interactions with other hypothalamic systems that mediate metabolic control and social responses, and exploring how the hypothalamic defensive circuits may influence emotional memory linked to predatory and social threats.
