Despite the mice being able to recognize the designated rewarding target within 9 days of training, the number of successful arrivals at the designated rewarding target in each session continues to increase with further training (Fig 3A–3C). Fig 3C plots the average number of successful arrivals at the designated target per session as a function of training time and shows that the number of rewards per session reaches the peak at day 13–14 of training, and then plateaus afterwards. Quantitatively, the average number of successful arrivals at the designated rewarding target per session was 0.03±0.03 for naïve mice during the Acclimation phase (D1-D3.5), 5.75±1.07 during the Baseline phase (D6.5-D9), and 18.29±1.95 during the Data Acquisition phase. An ANOVA test shows that the differences among these three groups are statistically significant (Fig 3A, F(2,75) = 62.18, P<0.001). Fisher’s PLSD post-hoc analysis shows that the differences between all three paired comparisons are statistically significant (Acclimation versus Baseline, P<0.001; Acclimation versus Data Acq., P<0.001; Baseline versus Data Acq., P<0.001). A Chi-squared test shows that the increase in the ratio of rewards versus failures significantly improved by the end of the Data Acquisition phase (Fig 3B, 1.5:1 at Baseline phase, to 7.6:1 at Data Acquisition phase, F = 114, P<0.001).
