Insula–amygdala circuits and alcohol abuse

Official title: Insula-amygdala circuits in alcohol abuse

Funded at Mclean Hospital · NIH-11393795 · Data updated 2026-11-12

This project studies how binge drinking changes brain circuits between the insula and amygdala to influence alcohol seeking and anxiety in a relevant animal model.

Who could benefit from this research

Could help

Not applicable to patients directly, as the study is in animal models; however, insights aim to inform future human therapies for AUD.

Less likely to help

Direct benefits to patients are not demonstrated within the animal study context.

What this research studies

Researchers will study how repeated binge drinking reshapes neural activity in the insular cortex and basolateral amygdala using an alcohol self-administration setup and anxiety-related behavioral tests. They will identify specific neuron populations involved in alcohol drinking and negative emotions, and examine how synaptic connections between these brain regions adapt with continued alcohol exposure. The work combines behavioral assays, in vivo measurements, and molecular analyses to map how neural plasticity relates to changes in alcohol-related behavior. Findings could explain why AUD persists and how affective states drive continued drinking in vulnerable individuals.

Why it matters

Potential benefit: A better understanding of brain circuits involved in alcohol craving and anxiety could guide new treatments for AUD and relapse prevention.

How similar studies have gone: Previous work supports that insula–amygdala circuits contribute to affective processing and alcohol-related behaviors, though the specific mechanisms in this pathway require further validation.
