Visual perception is somehow related to the function of our brain to understand the outer world where we are living. This brain function has biological significance because it successfully reconstructs the outer world in an ecologically meaningful manner: In other words, it reconstructs ‘Umwelt’ by von Uexkull. Essential components of our Umwelt are objects and their surfaces. In this article, I will introduce some of the works done by our group that are related to the neural representation of visual surfaces of objects such as color and Shitsukan, as well as the formation of visual surfaces.
