Fig. 1.

Line drawings of coronal sections from the brains of subjects with the maximum (dark gray) and minimum (light gray) damage resulting from electrolytic lesions of dorsal hippocampus (A), NMDA lesions of dorsal hippocampus (B), and NMDA lesions of retrohippocampal region (C). Starting from thetop, sections for the hippocampal lesions are taken from the following points in the AP plane (relative to bregma, in mm): −2.56, −3.14, −3.60, −4.16, and −4.52. Sections for the entorhinal lesions are taken from the following points: −6.30, −7.04, −7.64, −8.0, and −8.72. Drawings are from Paxinos and Watson (1998).
