Figure 5

Effect of EPT on memory deficits of the aged mice in the step-down passive avoidance test. Figures 5(a)5(c), 5(d) and 5(e), and 5(f)5(h) represent the tests of acquisition, consolidation, and retrial, respectively. Figures 5(a), 5(e), and 5(f) show the time spent on electric grid; Figures 5(c) and 5(h) show latency; and Figures 5(b), 5(d), and 5(g) show the time spent in safety zone. Values represent mean ± S.E.M ( 8–10 in each group). Gal 3 mg/kg represents galantamine 3 mg/kg group. and , versus the normal control group; and , versus the aged control group.
