We functionally mapped areas within the human posterior lateral-occipital (LOC) and hMT/V5 complex. Using a topographical alignment and correlating retinotopic with unsmoothed functional data we developed a fMRI group analysis, which is specific to within fractions of the individual areas. We demonstrate that the human MT/V5 complex includes the homologue of the macaque MT/V5 field-map cluster, consisting of areas V4t, MT/V5, MSTv, and FST. We further show that these areas can be sharply distinguished from neighboring areas in LOC based on functional characteristics and that a previously reported overlap of motion and shape responses coincides with areas V4t and FST.
