Figure 1.

Placement of cannula tips in the prelimbic and infralimbic areas for rats included in the behavioral analyses for experiments 1 and 2. Cannula tips were concentrated in the prelimbic area 2.7 to 3.7 mm anterior to bregma. Rat brain sections were modified from the atlas of Paxinos and Watson (1996). The number of circles does not match the total number of rats included in the behavioral analyses because certain cannula placements were overlapping to such a large extent that a single circle represented more than one cannula placement.
