Experiment 2 examined the effect of muscimol infusion into nucleus accumbens on expression of conditioned defeat. Asterisks indicate significant difference from vehicle. The lack of effect observed in unilateral and bilateral misses infused with muscimol demonstrates that the effect of muscimol in the nucleus accumbens is anatomically specific.
