Figure 3.

Postoperative training and testing of NOR on four different days in sham operated animals (CON, n = 47) and animals with hippocampal lesions (H, n = 44). Performance was scored over 15 sec of cumulative object exploration (A) and over 30 sec of cumulative object exploration (B). The left side of each panel (line graphs) shows the percent preference for the novel object on four different days for both the hippocampal lesion group (black circles) and the sham group (white circles). The right side of each panel (bar graphs) shows the 4-d mean for the hippocampal lesion group (black bar) and the sham group (white bar). Asterisks indicate group differences (* P = 0.059, ** P < 0.05).
