To determine how mice improve their performance with training, we analyzed their movement in more detail. Our results show that, after the advanced training, mice traveled a farther distance during each session (Fig 3D) without reducing the distance for each reward (Fig 3E). The average distance per session was 24.39±3.49 meters (m) during the Acclimation phase. During the Baseline phase it was 216.81±24.98 m/session, and finally 343.80±29.75 m/session during the Data Acquisition phase (Fig 3D). An ANOVA test shows that the differences among these three groups are statistically significant (F(2,75) = 63.64, P<0.001). Fisher’s PLSD post-hoc analysis shows that the differences between all three pair-wise comparisons are statistically significant (Acclimation versus Baseline, P<0.001; Acclimation versus Data Acq., P<0.001; Baseline versus Data Acq., P<0.001). On the other hand, the average distance traveled for each reward was 14.59±1.45 m during the Baseline phase, and 14.24±1.14 m during the Data Acquisition phase. A paired Student t-test shows that this reduction is not statistically significant (Fig 3E, df = 18, t = 0.02, P>0.05).
