The psychedelic psilocybin has shown therapeutic potential, yet underlying neural mechanisms remain poorly understood. We investigated the impact of psilocin-the active metabolite of psilocybin-on basal activity and reactivity within the paraventricular nucleus of the thalamus (PVT) and PVT projections to central amygdala (CeA) in rats. Psilocin administration increased PVT c-Fos expression and...
Alcohol use disorder (AUD) is a highly prevalent disorder with limited therapeutic options. The central amygdala (CeA) is a critical brain region as dysregulation within the CeA and the corticotropin-releasing factor (CRF) system are associated with AUD pathology. CeA CRF1 receptors regulate alcohol drinking and have served as a therapeutic target in alcohol treatment. One emerging potential...
Psychedelics have experienced renewed interest following positive clinical effects, however the neurobiological mechanisms underlying effects remain unclear. The paraventricular nucleus of the hypothalamus (PVN) plays an integral role in stress response, autonomic function, social behavior, and other affective processes. We investigated the effect of psilocin, the psychoactive metabolite of...
