Histological identification of injection sites. A, Representative injection sites in the bilateral elPB identified with Lucifer Yellow are labeled as yellow (scale bar, 500 μm). B, Atlas from Franklin and Paxinos [15] corresponding to the level shown in A. The bilateral elPB are shown with black bold lines. C, Injection sites are indicated with red lines filled with shaded yellow for all animals used for the behavioral analyses. Each panel corresponds to the area shown with a rectangle in A and B. Numbers on the left indicate antero-posterior levels relative to the bregma. Black bold lines correspond to the bilateral elPB as shown in B.
