Figure 1. Noisy motion perceptual discrimination task
Monkeys are presented with a visual motion stimulus in which a field of dots move either left or right and the monkeys have to report the direction of motion with a saccadic eye movement—typically with a leftward or rightward saccade for leftward or rightward motion, respectively. The amount of “noise” in the stimulus is controlled by altering the fraction of dots that move in a coherent direction (signal) and the fraction that moved in random directions (noise). As expected, monkeys’ decisions are less accurate for noisier stimuli. a) MT configuration with the noisy motion stimulus in the response field (RF) of the MT neurons under study and the saccade targets elsewhere. b) LIP configuration with one of the saccade targets in the RF of the LIP neurons under study, the other saccade target in the opposite visual hemifield and the noisy motion stimulus placed centrally.
