In the blind hemifield of the 8 patients with unilateral damage to V1 and in patient SBR with bilateral V1 damage, the %BOLD change in hMT+ to high contrast stimuli (50% and 100%) is significantly higher than that to low contrasts (1%, 5%, 10%). Healthy control participants (n=8) also show a higher response to the high contrast stimuli, but performance would be at ceiling for both high and low contrast detection (note the different scale on both axes). Signal change and performance scores are also provided for each contrast level separately.
