This study is for adults with major depressive disorder (depression) who are currently taking an SSRI or SNRI antidepressant but continue to experience anhedonia (reduced interest or pleasure) and emotional blunting. The study will test whether a single 25 mg dose of psilocybin, compared with placebo, can improve these symptoms and improve the function of brain circuits involved in reward and motivation. Researchers will measure changes using brain imaging (fMRI) and clinical questionnaires, including the Dimensional Anhedonia Rating Scale (DARS).
