  |  Atsushi Iriki  |  Cognitive Neurobiology

I aim to uncover evolutionary precursors of human higher cognitive functions grounded onto physical morphologies and patterns of structured bodily actions, based on behavioral and neurophysiological analyses on chronic macaque monkeys, which were trained to use tools and other high-tech apparatus. By sharing these machineries among individuals, we extrapolate the mechanisms to constitute bases of communicatory functions, and eventually understand neural mechanism to form intellectual and alstristic society to comprise humanistic civilization environment. Further, we are aiming at elucidating neurobiological mechanisms, through the development of Marmoset experimental models, of evolutionary as well as developmental processes that give rise to symbolic cognitive functions subserving inference, metaphysical thoughts, etc. that characterize human intelligence.
