| Research Abstract |
We investigated the mechanism how our brain generates motor commands in real-time manner under the constraints of our body, neural system and environment, by theoretical and experimental studies. Four primary results have been obtained. 1) We constructed a control model named "adaptive intermittent control," and illustrated that it well explained the human behavior in a continuous motor task. 2) We developed a novel method which detected a phase shift of stationary brain wave using a single-trial EEG data and found the relationship between the occurrence of phase shift and reaction time of a simple reaction-time task. 3) We analyzed the relationship between the eye and hand movements of moneys during a circle drawing task, and found that the money performed a continuous drawing task with dividing it into multiple discrete segments. 4) We clarified how the neural representation in monkey's parietal region changes on the way of visuomotor task using an information analysis technique.
