BackgroundPsilocybin and MDMA produce rapid, enduring therapeutic effects in posttraumatic stress disorder (PTSD); however, the underlying cellular mechanisms remain incompletely understood. In this study, we investigated whether adult myelin plasticity contributes to the therapeutic actions of psilocybin and MDMA in a rat model of contextual fear conditioni...
