Adolescent alcohol exposure has been associated with increased alcohol consumption in adulthood, indicating lasting consequences of adolescent drinking. Regarding somatostatin (SST) neurons, there has been little examination of changes in prelimbic SST neurons following adolescent alcohol consumption. The goal of this project is to 1) examine the effect of adolescent alcohol consumption on mouse behavior and to 2) examine the effect of adolescent alcohol consumption on brain connectivity, structure, and function.
