The amount of time (secs) that the experimental rats spent initiating interaction with the partner rats during a 5 min SI test, under four conditions. The first bar represents pre L-AG infusion baseline. Four days after L-AG infusion an SI test was done following an injection of saline (bar 2), 20 pmoles of muscimol (bar 3), or 100 pmoles of muscimol into the BNST. Treatments 2 – 4 were administered in a counter balanced design. Bars represent the mean and error bars represent the SEM. * Significantly different from pre-LAG baseline (paired t-test) and both doses of muscimol (Tukey’s posthoc test following ANOVA), # significantly different from 100 pmoles of muscimol (Tukey’s posthoc test following ANOVA). *,#, p<0.05.
