Accuracy change between predistractor and C+T period in KO mice. A, The four panels show scatter plots of the number of omitted trials (x-axes) and accuracy (y-axes) for all KO (n = 17) and WT (n = 15) mice in the first 4 d of the behavioral protocol. The yellow and green symbols represent the subsets of KO mice with altered (KO bad CR1) and compensated behavior (KO good CR1) according to the first criterion during the C+T period. B, Number of correct responses (x-axes) and accuracy (y-axes) for all KO (n = 17) and WT (n = 15) mice in the first 4 d of the behavioral protocol. Notice that, according to accuracy, during the first 3 d of the experimental protocol (PRE), KO and WT mice cannot be separated, but a significant separation of groups can be performed during day 4 (first day with C+T distractors). Using the second criterion of <77% accuracy (dotted lines), we can identify eight KO mice and only one WT mouse shown with black diamond symbols (Fisher's exact test, p = 0.018). Green symbols with a cross inside represent KO mice with compensated behavior in both criteria (KO compensated).
