Figure 1.
Excitotoxic lesions of the hippocampus and entorhinal cortex. The black shaded regions indicate the smallest lesion observed and gray shaded regions indicate the largest lesion observed. (A–C) depict the hippocampal lesion at three different anterior–posterior locations (approximately -2.76, -4.80, and -6.36 mm from bregma). (D–F) represent the entorhinal cortex lesion at three different anterior–posterior sites (approximately -6.36, -7.20, and -7.68 mm from bregma).
