Rostrocaudal extent of mPFC lesion placements. Reconstructions of dorsal (blue) and ventral (red) excitotoxin lesions throughout the bulk of their rostrocaudal extent in mPFC. In each column, solid areas of color represent areas of damage common to all members of each group, and color outlines represent the extent of individual lesions. Dorsal lesions target primarily the PL, with consistent involvement of ventral ACd, whereas ventral lesions are focused in IL, with variable spread into ventral PL. Atlas plates are adapted from Swanson (1992); their distance in millimeters relative to bregma is indicated. AP, Anteroposterior; ACv, anterior cingulate cortex, ventral subdivision.
