Alcohol Triggers Opioid Peptide Release in the Brain's Emotion Center
Acute ethanol directly triggered release of endorphin and enkephalin peptides in the central amygdala (the brain's emotion/fear center), measured by real-time microdialysis — the molecular basis for alcohol's emotional effects.
Quick Facts
What This Study Found
In-vivo microdialysis showed acute ethanol directly triggered beta-endorphin and met-enkephalin release in the central amygdala, providing real-time evidence for alcohol's emotional/anxiolytic effects through local opioid peptide release in the brain's fear center.
