Abstract

The present study aimed to investigate this tripartite relationship, regarding MRCP as a physiological index, ballistic movement as an index of operation and accuracy of the task performance. Experiments were conducted 'reaching' task; the subject touches the target appears 300 pixels away from the start point in a vertical direction on the touch sensitive screen with the forefinger. During experiments, EEG, EMG as trigger, image by high-speed camera and the efficiency of task were acquired. As a result, significant differences between the high and poor performance groups were clear on the NS in MRCP acquired from Fz(p p p
