Figure 3

Coronal sections at the level of the nucleus accumbens depicting the subregions targeted by microinjections used in the present experiments. Closed circles denote microinjections in the medial limb of the nucleus accumbens shell. Open circles denote infusions into the nucleus accumbens core. Numbers indicate distance from bregma in the anteroposterior direction. Representative microinjection sites are displayed for the accumbens shell (top panel) and core (bottom panel) in the inserts. Black arrows indicate ventral ends of microinjector tips in the accumbens shell and core. The grey arrow in the top panel indicates a guide cannula track aimed at the accumbens shell. Images were visualized with a light microscope using a 4× objective. Data from animals with necrotic or mechanical damage at microinjection sites were excluded from these experiments. AC = anterior commisure.
