Lysergic acid diethylamide (LSD) reduces activity in brain areas important for self-processing and social cognition, and decreases the efficiency of establishing joint attention. These effects are attributable to stimulation of the serotonin 2A receptor (5-HT2AR), as they are blocked by the antagonist ketanserin. The findings point toward the 5-HT2AR system as a potential target for treating social impairments in psychiatric disorders.
