DMS dopamine responses to contralateral stimuli are not because of the task motor requirements. A, Schematic of no-movement task. After a 1.5-s period of no wheel movement, a stimulus appeared on the left or right side of the screen. Mice (n = 3) had to hold the wheel still for a further 1.5 s to receive a reward. B, Wheel position in no-movement, move left, and move right trials averaged across all trials of all sessions. C, Stimulus aligned normalized mean DMS responses in trials in which mice successfully held the wheel still, separated by stimulus contrast.
