(a) Dwell times (see Methods) were shorter (T(18)=3.67, p=0.002, paired t-test) in the CS than in the US. In US, there were no effects of the reward probability of the target on the dwell times (F(2,18)=0.2, p=0.82, one-way ANOVA). (b) Variation of the instantaneous speed in certain setting: in the CS, the maximal speed of WT mice depended on the ICSS intensity (F(2,18)=13.2, p<0.001, one-way ANOVA) in contrary to what was observed in the uncertainty setting (US) with different probabilities of reward (see Fig 1e).
