Research Summary

Kentaro Miyamoto (Ph.D.)

In our daily life, we repeat decision making for future actions under continuously changing environments and human relationships. For a better decision making, conscious evaluation of one's own thought (introspection) and understanding of others' will (sympathy) are essential. Our team investigates brain mechanisms for prospective decision making in primates including humans and aims to reveal how our "self-awareness" and "imagination for others" are generated.
