Abstract

Females are at a higher risk for developing stress and anxiety disorders than males. In fact, female rats show a heightened fear response linked to the basolateral amygdala (BLA) activity in the brain. We tested the hypothesis that neurons in female BLA are more excitable than male counterparts due to decreased expression of a protein, KCa. We compared this protein's expression in the BLA betweem female rats at varying stages of their estrous cycle and males. Our preliminary data shows a trend consistent with our hypothesis. Once completed, these studies will aid in understanding how sex differences underlie anxiety disorders.
