Towards Functional Differentiation: Its theory, function, and development

Functional differentiation of the brain is the most fundamental issue for living agents to generate physical and mental activities. However, the mechanism how different functions can be realized is still one of the big mysteries. We attempt to approach to this issue from three different but closely related perspectives. They are mathematical formulation, function assignment, and development. The principle of the functional differentiation is based on the information theory, and simulation of functional differentiation with physical body and neural architecture is implemented. fMRI studies show the developmental functional differentiation from school kids to adults. In this talk, I will introduce these attempts and discuss how they can be linked together.
