Neural mechanisms for reconstruction of 3D visual world in the brain

Visual world has 3D structure. However, visual images on retina are data only with 2D structure, thus, the brain has to reconstruct 3D structure from those data. In the visual word, there are two targets for our 3D perception. One is the 3D space such as our living town and our working building etc. During moving in such environment, we construct the cognitive map of the environment in the brain. Another target is the objects with 3D structure which are in the environment. We can manipulate these objects correctly when we perceive 3D structure of those correctly. In this study, we examined neural mechanisms for reconstruction of 3D visual world in the brain by electrophysiological, neuroanatomical, brain imaging and psychophysical techniques.
