Performance in the delayed nonmatch to sample (DNMS) task. Number of trials (top) and percentage of correct responses (bottom), considering all trials (total, first column), trials where the random delay was less than 15 s (short delay, second column), and trials where the random delay was more than 15 s (long delay, third column). Blue corresponds to controls and orange to transgenic rats. Significant differences between groups are indicated: * p < 0.05 and ** p < 0.01
