Official title: Anterior Insula Projections for Alcohol Drinking/Anxiety Interactions in Female and Male Rats
Funded at Indiana University Indianapolis · NIH-11124752 · Data updated 2026-11-12
This project looks at specific front-insula brain circuits that may drive compulsive alcohol drinking and anxiety, with attention to differences between females and males.

Who could benefit from this research
✓Could help
Although this is preclinical lab research and does not enroll patients, the findings would be most relevant to adults with alcohol use disorder who keep drinking despite harm, particularly those with co-occurring anxiety and women.
✕Less likely to help
People with mild or social drinking without compulsion, or those whose problems are unrelated to anxiety, are less likely to benefit directly from these circuit-focused findings.
What this research studies
Researchers use rat models to map and manipulate front-insula brain pathways and measure how those circuits influence persistent, consequence-resistant drinking and anxiety-like behavior. The team compares males and females to find sex-specific similarities and differences in the circuits that promote heavy drinking. Experiments focus on connections from the anterior insula to reward regions like the nucleus accumbens and test how altering those projections changes drinking under negative consequences. Results aim to reveal circuit targets that could guide future treatments tailored by sex.
Why it matters
Potential benefit: If successful, this work could point to brain-circuit targets that lead to better, more personalized treatments for people with compulsive alcohol use and co-occurring anxiety, especially women.
How similar studies have gone: Prior animal and human imaging studies implicate anterior insula circuits in compulsion-like alcohol drinking, but detailed sex-specific circuit mechanisms remain incompletely tested.
