Rats' leaving is triggered by the stimuli.

<p>A) Proportion of trials in which the rats left the nose-poke, as a function of time from nose-poke onset. Trials were divided into two categories: early onset - those in which the stimulus was active by 655 ms (i.e. those that start within the green rectangle) and late onset - those in which the stimulus became active after 655 ms (those that start within the red rectangle). The black line indicates the proportion of active stimuli. The green line indicates the proportion of trials in which the rat has left nose-poke when the stimuli began before 655 ms, the red line after 655 ms. B) A Q-Q plot, with 10% quantiles, comparing the distributions in panel A. C) A plot of the difference between the cumulative proportion of nose-poke leaving in early onset trials versus late onset trials; i.e. the cumulative difference between the red and in green curves in 4A.
