Abstract(in English) The SKE is the visual phenomenon that a stimulus rotating in a front-parallel plane about visual axis can create the impression of a 3-D object. We can segregate depth, motion and shape information processing by using the SKE. We performed fMRI to investigate how motion and shape contributed to depth perception. It was suggested that the occipito-temporal area including MT+, LO and V3B played an important role for extracting depth information. It seemed that the dorsal intraparietal area including DIPSM and DIPSA was involved in calculation of the track of a perceived 3-D object, and that the ventral intraparietal area including V3A, V7 and VIPS was involved in intermediate information processing.
