Histologically verified placements of viral injections and optical fiber tips in ChR2 animals used for pharmacology experiments. A, Coronal sections of the BLA with coordinates reflecting anteroposterior distance from bregma. Center of viral injections in the BLA for all mice expressing ChR2 (n = 8; purple circles). B, Coronal sections of the vHPC with coordinates from bregma. Location of cannulae above the pyramidal layer of vHPC for ChR2 animals (purple crosses).
