概略/About

I am interested in how relationships in society - parent-child, family, school/peers, community, country, etc. - are biologically embedded within individual and make people who they are, and in turn how individual existence is externalized into the relationships. The role of the brain is my primary focus within biological embedding, as the brain functions as a receptor of external stimuli, an interpreter of those stimuli and an effector of the external environment. I am also interested in how these interdependent relationships between society and the individual through the brain continue with dynamic changes throughout life, across multiple generations, and even historically.
Ultimately, I hope to clarify the nature of human beings as social creatures, and thereby uncover an ideal social design that allows each individual to realize their full capability and live their own life.
