a Schematic representation of successive coronal sections of the mouse brain showing the histological verification of injection placement into the IL PFC (n=16) (rostral to caudal: 1.98 and 1.94 mm anterior to the bregma). IL infralimbic cortex; VO ventral orbital cortex; Cgl cingulate cortex, area 1; PrL prelimbic cortex; MO medial orbital cortex; LO lateral orbital cortex; M1 primary motor cortex; M2 secondary motor cortex; DP dorsal peduncular cortex. All images are adapted from Paxinos and Franklin (2001). b Photomicrographs showing correct placement of guide cannula and microinjection at IL PFC region
