Figure 1.

Functional identification of cortical areas V5/MT+ and V3A. Regions of the brain that are most significantly activated by the passive viewing of moving gratings (see Materials and Methods for details) are shown. Areas of most significant activation (p _{(uncorrected)} < 0.0005) are shown for two representative observers (N.C., M.P.B.). There is bilateral activation of the lateral occipito-temporal cortex in a location that is consistent with that of area V5/MT+. In addition, bilateral activation in a region of the superior occipito-parietal cortex can also be observed, and this region lies in close proximity to an area that has been previously identified as V3A.
