Figure 3—figure supplement 1
Comparing DA responses to CSs in lesion-affected and intact visual field.

These figures show firing rate of DA response to CS presented into lesion-affected and into intact visual field. Responses to LR-CS were compaired in A, and to SR-CS were in B. Time windows size to …
