Contrast affects fMRI activity in middle temporal cortex related to center-surround interaction in motion perception
As the size of a high contrast drifting Gabor patch increases, perceiving its direction of motion becomes harder. However the same behavioral effect is not observed for a low contrast Gabor patch. Neuronal mechanisms underlying this size-contrast interaction are not well understood. Here using psych...
