Neuroendocrine Response to Oral Alcohol Administration

• Status: Completed
• Trial end date: 2018-06-30
• Target enrollment: 0
• Participant gender: All

Summary

This study proposes to examine both the peripheral and central nervous system responses when light social drinkers and binge/heavy social drinkers are exposed to oral ethanol. The findings will provide a greater understanding of the brain mechanisms (cerebral blood flow and functional connectivity) underlying the association between stress, cortisol release, heart rate variability, alcohol craving, and alcohol stimulant and sedative effects. This knowledge could be significant in developing new therapies for the treatment of alcoholism.
