| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The perceived size of an object remains relatively stable despite changes in the size of retinal images accompanying changes in distance from the observer. In this perceptual phenomenon (size constancy), the brain uses distance information for calibrating the perceived size. Binocular disparity provides a clue about distance. To examine interaction between binocular disparity and stimulus size information, we recorded neuronal responses in the macaque cortical are V4. Half of V4 cells showed significant interaction between the tunings for binocular disparity and size. This behavior of V4 cells was consistent with psychophysical performance of human observers. The results suggest that V4 cells contribute to size constancy. | |
