ABSTRACT
Recent neuroscientific studies on the cerebral mechanism of vision in animals and man have revealed that modular organization is the basic principle underlying visual information processing in the brain (Ungerleider and Mishkin, 1982; Macko et al., 1982; Macko and Mishkin, 1985; Iwata, 1989; Zeki, 1992). That is to say, the brain consists of a number of independent computers, each one of which is specialized for analyzing a special feature of the visual information coming from the outside world. Each individual special feature of the information to be analyzed separately is called a “module,” and the system of such division of labor is called “modular organization” ( Marr, 1982). Table 1 shows the modules that are known to be processed by a certain specific cortical area.
