Fig 1. Schematic representations of coronal sections at the level of the amygdala both (A) showing the estimated infusion-cannulae tips placements aimed at the BA, with triangles representing PBS-infused rats (PBS) and circles representing muscimol-infused rats (MUSC), and (B) representing the minimum (black shading) and maximum (gray shading) extent of lesion caused by 0.16 μl of quinolinic acid infused after completion of behavioral testing, thus reflecting approximately the region reached by the muscimol and the PBS infusion, of all subjects which data were included in the behavioral analysis.
