Hominization of Cognition, Hominization of Computer

Hominization of the brain is the evolution of the human brain traits that discriminate the genus Homo from its primate ancestors. Evolution of the brain started with the reeex brains in vertebrate animals as such the sh, but the brain functions of volition, the autonomic nervous system and dexterous control are mammalian. Thinking and emoting are functions demanding enormous brain capacity. An adaptation was made by converting the right-left duplicate brains into a huge single brain. In the human's cognition, one of the characteristics of hominization is an evolutionary hierarchy of the information centers: Its ascending limbs consist of (1) the primary sensory cortices, (2) higher order sensory cortical areas and (3) the association cortices, and its descending limbs consist of (4) higher order motor cor-tices that feed (5) the primary motor cortices. We may intervene in the processing, especially that taking place in the association cortices: we monitor and manipulate the processing by retrieving, modifying , storing or replaying the informational material: thinking whatever at all. Here we have a virtual experience. This ability expands to processing even in the substantial absence of any perceivable objects, enabling us to communicate with verbal words and with symbols and letters, too. Pavlov's experiment on the conditioned reeex reveals one of the ways in which the perception of an object can be made speciically meaningful. An act becomes so closely intermeshed with emotion and volition that you will have pleasure in doing it. This ability is furthered by the so-called crystalization of Stend-hal: it is a way of magiication. We may apprehend the critical signiicance of a matter or indulge in daydreams. The activity of the brain is characterized as \on-demand" rather than \full-time" functioning, and so is its metabolism. The cerebral arterial system has a special device for prompt on-demand delivery (Okuyama, 1992). This saves energy and prevents oxidative vas-cular damage as well. Computer technology rst was developed so as to substitute for human manual writing and computation, but it soon turned out also to be useful in increasing human cognitive power: e.g., in an improvement of our density resolution by digital coloration (Okuyama et al. 1979). We can train ourselves so as to better operate computers , in an adaptation of the human being to the machinery. We can transform ourselves into wonderful users when interest and pleasure grow in operating computers even without any proots from such growth. However, …
