Figure 1.
Schematic representation of excitotoxic lesions of the NAC core (A) and shell (B) for Experiment 1. Shaded areas represent the maximum (dark gray) and minimum (light gray) extent of the lesions for the animals included in the behavioral analyses. Coronal sections are taken from the following points in the anteroposterior plane beginning at top left: +1.7, +1.2, +1.0, and +0.7 mm anterior to bregma (Paxinos and Watson, 1998). C, Schematic representation of the placement of cannula tips for the NAC core (left) and shell (right) groups for Experiment 2.
