Figure 1 :

Rat behavior on the contingency switching task. (A) The contingency switching task is a spatial maze consisting of a central maze segment, a choice point, and reward zones where rats receive rewards dependent on making choices consistent with the current contingency. (B) Example of a pass through the choice point where the rat displayed VTE and (C) a non-VTE pass. Bold lines show the position of the rat’s head during a pass through the choice point. Gray dots show the position of the rat’s head throughout the entire session. (D) Contingencies are presented in blocks of laps lasting 30 ± 5 trials. (E) Example behavioral data from a single session.
