Figure 5. The CS intensity and consistency affect the memory retrieval.

Figure 5

(a–c) Top: training and testing scheme. Bottom: decreasing the intensity of cue produced significant deficits in DEC retrieval, but increasing the intensity of cue produced significant improvements in CR performance (n = 8 rats for both reduced 10 + 40 and enhanced 10 + 40 groups and n = 9 rats for Medium 10 + 40, control group; N.S., not significant, *P < 0.05; one-way ANOVA followed by Tukey post-hoc test). (d–f) Top: training and testing scheme. Bottom: changing the consistency of CS produced significant deficits in DEC retrieval (n = 8 rats for 2 + 8 group and n = 9 rats for Medium 10 + 40, control group; N.S., not significant, *P < 0.05, **P < 0.01; two-tailed unpaired Student’s t-test). (g–i) Top: training and testing scheme. Bottom: decreasing the intensity and consistency of cue produced significant deficits in DEC retrieval, whereas decreasing the consistency and increasing the intensity of cue produced significant improvements in CR performance (n = 8 rats for 5 + 45 group, n = 9 rats for Medium 10 + 40, control group, and n = 10 rats for 30 + 20 group; N.S., not significant, *P < 0.05; one-way ANOVA followed by Tukey post-hoc test). Data are represented as mean ± s.e.m.
