Description<\/h2>\n

How can human as well as other animals respond to constantly changing environment in spite of inevitable time-delay required for processing and transferring information in sensory-motor system? A predictive mechanism should exist in order to compensate this delay or to generate appropriate behavior.<\/p>\n

In relation to the predictive function for compensating the delay in visual-motor system, a number of psychophysical studies on hand\/eye-tracking behaviour have been carried out by using a variety of stimuli, including simple harmonic frequency. Yasuji et. al investigated particularly the proactive nature of the visual-motor system by steady and transient experiments of a hand-tracking task, and confirmed that the hand-motion precedes on the average the target-motion in steady runs within a finite frequency range of the sinusoidal target-motion. The question why and how much the hand-motion should precede was answered by frequency-jump experiments. The results implied that the positive phase-shift of the hand-motion represents the proactive nature of the visual-motor control system which is adaptationally developed for each person to minimize the transient error of the hand-motion when the target-motion changes unexpectedly.<\/p>\n

It is critical to co-register the EEG signal and kinematics of motion to measure the continuous iterative loop between brain and body, to this aim, we developed the real-time EEG\/robotic system. The project will investigate the brain mechanism of proactive control in which dynamical minimization is achieved, using the functional connectivity and topological analysis.<\/p>\n
