Abstract(in Japanese) (See Japanese page)
Abstract(in English) Daily-experienced visual motion is first-order motion cued by the spatial distribution of luminance or color discontinuity. Second-order motion is another kind of motion cued not by luminance but by some higher cues such as texture. In order to elucidate neural substrate for the detection of second-order motion, we examined psychophysical performances of humans and response properties of MT and MST cells of the monkey to second-order motion stimuli. Both MT and MST cells showed very weaker responses to second-order motion than first-order one. Human observers reported very different performances in first-order and second-order motion perception. These results strongly suggested that second-order motion signals is processed largely in other areas than those involved in first-order mechanism.
