Figure 3.

Color-coded overlays of activity for additional contrasts, depicted as in Figure 2. On the left and right sagittal views (top and middle rows, respectively), the red and yellow overlays demonstrate the effect of stimulus type in either hemifield: red demonstrates activity in the contrast of LR with LF, and yellow demonstrates activity in the contrast of RR with RF. Pink demonstrates areas of overlapping activity for the two contrasts. The bottom row shows these overlays on selected sagittal (left), axial (middle), and coronal (right) planes, with the x, y, and z planes in millimeters.
