Figure 1.
(A) Cortical maps of the enhancement index IE for patches with a radius of 1 cm, averaged over all subjects and displayed in anatomic atlas space. The first and second rows of images show EEG and MEG enhancement profiles, respectively. In both cases, only the left hemisphere is shown because the results for the right hemisphere are very similar. As shown from left to right within each row of images, the views are: lateral, medial, posterior, anterior, ventral (top) and dorsal (bottom). The cut surfaces of the diencephalon and corpus callosum are excluded (shown in white). The color scale varies from the lowest to the highest value of IE over the cortex. (B) As in (A), for the orientation uniformity index IU = 1 − IO, where IO is the disparity index.
