Outline of Final Research Achievements

Visual images projected to right and left eyes are slightly different from each other. The difference is called binocular disparity. Binocular disparity provides a clue for 3D perception and is processed among various visual areas. In this study, for investigating neural circuits processing binocular disparity, we developed recording techniques for monkey visual cortex using in vivo 2-photon calcium imaging, which had been mainly used for small animals, such as rodents. By using this technique, we showed a spatial arrangement of neurons according to their response properties and published the results in a scientific journal.
