Schematic representation of the position of the injector tips in Experiment 1 (muscimol microinfusions; 0.5 μg/0.5 μl/side) as revealed by histological analysis. The sagittal view approximately shows the areas targeted by injectors on the horizontal plane. Empty triangles, anterior cingulate cortex (ACC, n=4); filled circles, dorsal prelimbic cortex (dPL, n=12); empty circles, ventro-medial prefrontal cortex (vmPFC, n=10); filled triangles, orbitofrontal cortex (OFC, n=9). Drawings adapted from Paxinos and Watson (1998).
