Figure 2.

Reverse correlation analysis (reproduced from Kiani et al., 2008). (A) Expected separation of motion energy profiles for rightward (red) and leftward (blue) choices for bounded diffusion (top) and leak-dominant LCA (bottom). Late information is more critical in the leak-dominant LCA model while early information is more critical in the bounded diffusion model. (B) Left, signals aligned with motion onset, right signals aligned with motion offset. One can observe that in the data (Panel B), the difference between the evidence that favors the response (red) and the one that opposes it (blue) is larger at the beginning of the choice interval.
