Success rate per delay in the delayed non-matching to position test.

<p>The graphs show the success rate on trials with delays of different durations in the delayed non-matching test. (A) shows the stable baseline performance of rats maintained on the standard food restriction protocol at four months of age. (B) and (C) show the age progression of performance for WT and BACHD rats, respectively. Curves display group mean plus standard error. Results from two-way repeated measures ANOVA are shown inside the graphs. For (A), results from <i>post-hoc</i> analysis are indicated in case significant genotype differences were found. * (<i>P</i> < 0.05) ** (<i>P</i> < 0.01) *** (<i>P</i> < 0.001).
