[Vision].

The existence of two visual information pathways has gained acceptance, and the entire scheme of visual information processing has been understood. The visual cortex has been subdivided into areas, whose neurophysiological properties have been examined in the monkey. Our understanding of the visual processing system has been built by information earned in parts. However, despite knowledge about the complete process, the associations between the individual components remain to be understood. In addition, elucidating the neural basis of perception experienced in daily living would be a challenge in the future.
