Figure 3.

The dorsal and ventral visual processing streams in human cortex, as demonstrated in a PET study of location and face perception. Areas shown in green had significantly increased rCBF during the location matching but not during the face matching task, as compared with rCBF during a sensorimotor control task. Areas shown in red had significantly increased rCBF during the face matching but not during the location matching task, as compared with rCBF during the control task. Areas shown in yellow had significantly increased rCBF during both face and location matching tasks. Maximum location intensities are shown on the lateral views of the left and right hemispheres. Coronal sections are taken at the anterior-posterior levels indicated on the lateral views. (Adapted from ref. 45.)
