Activation to disparity, motion, object, and color stimuli in patient DF, an age- and gender-matched control participant, and the control group response. The activation to both disparity and objects is considerably reduced in DF. In contrast, the response to motion is extensive and highly significant. Note that, for DF, the cluster correction has not been applied to activations by objects, because this abolished any activation. The significance is lower in the images from the control group, because of the interparticipant variability, but the extent of activation is greater than in DF to all stimuli.
