Therefore, dopamine cells in the cerebrum basal ganglia are considered to be activated by expectation error or predicted expectation to reward. Rough but quick processing of information by the amygdaloid complex is the most primitive method of interpreting a symbol. Starting from this rough but quick interpretation of information, the brain acquires the meaning of the symbol by assembling information of the symbol on the basis of the brain s double structure and the associations of spatiotemporal information. The neocortex and the amygdaloid complex acquire extrinsic symbols in an output-dependent manner through the expression of endogenous symbols and processing of actual input from the environment. Rough but quick conceptualization by means of extrinsic symbol processing in the early stage and associations among multiple phases is called intuitive information processing.
Output is produced by intuitive interpretation of information.
As a result, meaning of symbols are refined and obtained. Furthermore, the study to clarify the mechanism of how the emotion controls brain activities is ongoing. Therefore, our study indicates that brain studies are highly compatible with humanities and social sciences which concern human nature and the social systems by which people can socialize. As a result, the fusion of brain science, which is categorized as a natural science, with humanities, social science, philosophy and religion may possibly pave the way to a new scientific paradigm.
