Direction-Cue提示に用いる刺激の種類が運動選択時の脳波に与える影響

抄録

We have tried to obtain knowledge of decision-making by analyzing EEG in the Cued-movements Task. The aim of using the Cued-Movements Task is to observe two factors separately. One factor is decision-making of movement-direction. The other factor is execution of movements.

In this paper, we performed the Direction-Cue Task with auditory stimuli and the Direction-Cue Task with visual stimuli. First, the Direction-Cue is presented. The Direction-Cue indicate direction for movements. Next the Go-Cue is presented. After presenting the Go-Cue, a subject starts a movement. In the Direction-Cue Task with auditory stimuli, the Direction-Cue is presented by right- or left-arrow on display. In the Direction-Cue Task with visual stimuli, the Direction-Cue is presented by beep tone.

As results, we found that the stimulus of modality of the Cue has the influence on EEG potentials in Cued-movements.
