Behavioral performance of WT and α9-nAChR KO mice in the 12-days experimental protocol. A, Accuracy increases in a parallel manner in KO and WT mice along days and, although there is a tendency in KO mice to have less accuracy in the fourth day of the protocol (first day of C+T period), no significant differences were found. B, Mean latency of correct responses diminished along days in similar manner in WT and KO mice. C, There are significant reductions in the number of correct responses in KO mice during the presentation of the C+T distractor in the fourth and sixth day of the behavioral protocol. D, In addition, although there was a tendency to have more omitted trials during the C+T period in KO mice, no significant effects were obtained in this analysis (*p < 0.05; all variables are plotted as mean ± SEM).
