Beyond Serotonin: The Comprehensive Brain Engagement of Psychedelics

A new study reveals that psychedelics like LSD, psilocybin, and mescaline interact with a wide range of neural receptors beyond just serotonin, engaging multiple pathways that may explain their complex effects and therapeutic potential. These compounds activate numerous serotonin, dopamine, and adrenergic receptors, stimulating diverse intracellular signaling pathways, which could allow for the development of targeted, non-hallucinogenic therapies for mental health conditions. The findings highlight the intricate pharmacology of psychedelics and their potential for precision medicine in neuropsychiatry.
