Serotonin's Impact on Brain and Behavior: A Comprehensive Study

Researchers at MIT have conducted a comprehensive study on serotonin, a key molecule in influencing mood and behavior, tracing its impact from the molecular level to the brain’s overall functioning using the simple animal model of C. elegans. The study identified the functional roles of the worm’s six serotonin receptors, revealing complex interactions between them that likely have direct relevance to psychiatric drugs targeting these receptors. Findings from this research could be crucial in improving existing psychiatric drugs and developing new ones targeting the serotonin system.
