Abstract
The discovery and the following investigation of the Motion Induced Blindness (MIB) are reviewed. The physiological mechanisms and functional organization of MIB are of most interest as a peculiar example of visual blindness. The natural Blind Spot (BS) has the perfect Filling-In (FI) functions. MIB could be identified with an Artificial blind Spot (AS). Recent research results by the authors are explained. Investigating the blindness, we could approach to our visual awareness issue which are of interest in physiology, psychology, cognitive science, and even in philosophy.
