| Abstract(in English) | Recent studies have revealed that human visual motion areas are involved in three-dimensional (3-D) object perception from binocular disparity cues. In the present study, adding a sinusoidal grating texture defined by luminance contrast to a crescent-shaped stereokinetic effect stimulus, which could give the impression of a 3-D cylinder, we investigated the involvement of the human middle temporal (MT) and medial superior temporal (MST) areas in monocular depth perception. Cortical activation associated with the luminance contrast of the stimulus texture was observed in MT as well as early visual areas and V4. In contrast, that with 3-D object perception was observed in MST as well as V3B, V7, and the lateral occipital area, suggesting that MST plays an important role in the integration of monocular depth cues of motion, shape, and texture. |
