Direct serotonin release in humans shapes decision computations within aversive environments

Michael Colwell, Hosana Tagomori, Fei Shang…·Catherine J. Harmer

This study uses a selective serotonin releasing agent to examine how increased synaptic serotonin affects decision-making in aversive contexts, finding reduced sensitivity to aversive outcomes and enhanced impulse control.
