Abstract

In mice chronic social defeat leads to a behavioral and physiological condition that resembles depressive states in human patients, including physiological dysfunction, anhedonia and motivational deficits. Lesions in the dorsal premammillary nucleus of the hypothalamus disrupt behavioral and neuroendocrine responses of animals exposed to one social defeat. In this project, we aim to investigate the metabolic alterations caused by the lesion of this hypothalamic nucleus in chronic social defeated animals. Once the hyper stimulation of the ventral tegmental area was implicated to be the source of these changes found in chronic social stress, we hypothesized that brain regions involved in social defense are also mediating the generation of the chronic state through the lateral column of the periaqueductal gray matter. This structure projects to the orexinergic neurons in the lateral hypothalamic area that is known to afferent the ventral tegmental area. We will test that hypothesis with optogenetic manipulations.
