Figure 4. Effect of GTP treatment on short- and long-term memory.

Figure 4

In wild type (WT, n = 10) and YACtg152F7 transgenic (TG, n = 10) water-fed (H2O) and in wild type (WT, n = 10) and YACtg152F7 transgenic (TG, n = 10) green tea-fed (GTP, n = 10). A: Spontaneous alternation test with two sessions of ten minutes each separated by 24 h: number of alternations/total number of possible alternations ×100 (AS1). B: Object recognition test: difference in exploration time between the new and familiar objects, in percentage of total time spent exploring the two objects; 100×(N−F/N+F). ** for p<0.01, * for p<0.05. according to Wilcoxon test results (two-way ANOVA in supplementary data). C: Object recognition test on WT H2O-fed (n = 10), WT polyphenon-fed (n = 10) and TG polyphenon-fed (n = 6) (no significant differences between the three groups).
