FIGURE 9. Boundaries Defining Plane C (from figure 7) of the Cortexa.
a The plane was defined by two parallel lines, the first of which is depicted in the midsagittal MRI slice on the left as a straight line drawn through the parieto-occipital fissure. The second line was drawn with identical x, y coordinates as the first line and is shown on the more lateral sagittal MRI slice on the right.
