FIG. 3.

Distances along the surface of the cortex between pairs of ROIs. Distances were computed within a hemisphere using the quadrant division of ROIs such that there are two full quadrants considered per hemisphere, one dorsal and one ventral. The matrix presents mean distances computed across all five subjects and their two hemispheres. The defined eccentricity regions are labeled as e1, e2, e3, e4, and e5.
