Discrimination learning at short and long delays in WT and Tc1 mice in the object recognition task. The results are expressed as percentage of time spent exploring the novel (white bars) and familiar (back bars) objects. The horizontal line indicates performances close to the chance level. Tc1 mice show a recognition memory deficit at a 10-min delay (n = 7 WT and n = 9 Tc1) (A), but not at a 24-h delay (n = 9 WT and n = 10 Tc1) (B). Values represent means ± SEM. *P < 0.05, **P < 0.01, and ***P < 0.001.
