1. Responses measured by BOLD fMRI in areas V1, V2, V3, and MT+ as two subjects (S2, gray; S3, black) switched between the speed and the contrast discrimination task.
Responses measured by BOLD fMRI in areas V1, V2, V3, and MT+ as two subjects (S2, gray; S3, black) switched between the speed and the contrast discrimination task. Positive responses represent larger activity when subjects performed the contrast discrimination task. Note the change of scale along the y-axis. Two contrasts are shown. Error bars represent SEM.
