The aim of this study was to investigate the effects of cannabidiol (CBD) on memory deficits induced by ovariectomy and to directly compare its effects with those of hormone therapy, in order to better understand potential shared mechanisms related to menopause‐associated cognitive decline, with a particular focus on the endocannabinoid system. Three‐month‐old female Wistar rats were randomly...
Arginine vasopressin (AVP) modulates stress responsivity and social-affective behaviors, but its role in mood and trauma-related disorders remains poorly defined due to challenges in peripheral measurement. This study used copeptin, a stable, reliable, and well-validated surrogate marker of AVP secretion, to assess vasopressinergic function in a transdiagnostic sample of individuals...

Interest in LSD research in humans waned after the 1970s, although the use of LSD in psychiatric research and practice has recently gained increasing attention. LSD produces pronounced acute psychedelic effects, although its influence on plasma steroid levels...
