The emotional architecture of the psychedelic brain

Abstract

Serotonergic psychedelics are being explored as treatments for a range of psychiatric conditions. Promising results in mood disorders indicate that their effects on emotional processing may play a central role in their therapeutic potential. However, mechanistic and clinical studies paint a complex picture of the impact of psychedelics on emotions and mood. Here, we review recent findings on the effects of psychedelics on emotion, emotional empathy, and mood. We discuss how psychedelics may impact long-term emotion management strategies, the significance of challenging experiences, and neuroplastic changes. More precise characterization of emotional states and greater attention to the temporal dynamics of psychedelic-induced effects will be critical for clarifying their mechanisms of action and optimizing their therapeutic impact.
