There is considerable interest in the concept that psychedelic compounds might facilitate reorganization of emotional processing with therapeutic benefit; in particular, amelioration of excessive focus on past, current and potential-future aversive events, a dominant emotional-cognitive state in stress-related affective disorders. Translational animal models can advance understanding of...
In vivo , psilocybin is rapidly dephosphorylated to psilocin which induces psychedelic effects by interacting with the 5-HT 2A receptor. Psilocin primarily undergoes glucuronidation or conversion to 4-hydroxyindole-3-acetic acid (4-HIAA). Herein, we investigated psilocybin’s metabolic pathways in vitro and in vivo , conducting a thorough analysis of the enzymes involved. Metabolism studies were...

Hallucinogenic agents have been proposed as potent antidepressants; this includes the serotonin (5-HT) receptor 2A agonist psilocybin. In human subjects, psilocybin alters functional connectivity (FC) within the default-mode network (DMN), a constellation of inter-connected regions that displays altered FC in depressive disorders. In this study, we investigated the effects of psilocybin on FC...
