How teen binge drinking can change brain activity, sex hormones, and metabolism
Adolescent alcohol exposure: impact on neuronal activation, steroids, and metabolomic profiles
Looking at whether binge drinking during the teen years leads to lasting changes in brain cell activity, sex hormones, and metabolic signals in males and females.

What this research studies
This lab project uses an adolescent intermittent alcohol exposure model in male and female mice to mimic teen binge drinking and withdrawal. Researchers will measure neuronal activation and steroid hormone receptors in key brain regions involved in reward and decision-making, with attention to timing after withdrawal and after re-exposure. They will also profile metabolomic changes to identify biochemical signatures linked to early alcohol exposure. Although done in animals, the work aims to uncover sex-specific mechanisms that could explain why early drinking raises later risk for alcohol problems in people.
Who could benefit from this research
Good fit: People who began binge drinking during adolescence or adults reporting heavy alcohol use that started in their teen years would be most relevant to these findings.
Not a fit: Those whose alcohol problems began in adulthood or people seeking immediate clinical treatment may not directly benefit from this preclinical work.
Why it matters
Potential benefit: If successful, the work could clarify biological reasons why early binge drinking increases later risk for alcohol use disorder and point to hormone- or metabolism-related ways to prevent or treat it.
How similar studies have performed: Prior animal studies, including work by this team, have shown sex-specific brain and behavioral changes after adolescent binge alcohol exposure, but linking steroid receptors with metabolomic shifts is a newer direction.
