Representative non-overlapping placements of the injection sites within the medial prefrontal cortex (A, filled triangle), ventral pallidum (B, open triangle), nucleus accumbens (C, filled circle for shell sub-region and open circle for core sub-region), and posterior ventral tegmental area (D, filled square), according to the brain atlas of Paxinos and Watson (1998). Placements within the medial prefrontal cortex were mainly within the prelimbic subregion. Placements within the ventral pallidum were mainly in the ventral portion.
