(a) Mice were trained to locate each platform for 4 trials a day, with start locations randomly selected from the 4 cardinal coordinates (N, E, S, W). The start locations are shown. Mice were given a 1 d or 30 d delay after training. The time line for the first experiments (Fig. 1) is shown. (b) Time line for the weighted bimodal distribution experiments (Fig. 2) is shown. (c-d) Time lines for the Consistent vs. Conflict experiments (Fig. 3, Fig. 4 and Fig 6) are shown.
