Assistant Professor of Psychiatry and Behavioral Sciences

Research Interests: Neuropsychopharmacology; emotion; hallucinogens; serotonin; music; fMRI; PET


Dr. Barrett is a cognitive neuroscientist with training in behavioral pharmacology. He uses music and pharmacological interventions, along with behavioral measures, computerized testing, and brain imaging techniques, to explore the neural basis of emotional functioning and altered states of consciousness. His current research focuses on the acute and long-term effects of hallucinogens on cognition, emotion, and brain function. more
