Lysergic acid diethylamide (LSD) has been considered as a potential treatment for depression for over 75 years, but its therapeutic potential has only recently been considered in mainstream psychiatry. Repeated ingestion of low doses of LSD ("microdoses") is thought to reduce depression, but the neurobiology underlying this effect is unknown. We previously reported that low doses of LSD...
Despite widespread popular interest in the use of low doses of Lysergic acid diethylamide (LSD) to improve mood, little is known about how these doses affect emotional processing in the brain. In this study, we tested the effect of a single low dose of LSD (26 µg) compared with placebo on electroencephalogram (EEG) event-related potentials (ERP: N170, P300 and Mismatch Negativity) in healthy...

Single, high doses of psychedelic drugs have shown promise in treating depressive disorders, perhaps by reversing deficits in reward processing in the brain. In addition, there are anecdotal reports that repeated ingestion of low doses of LSD, or...
