Abstract
<p> In the present study, we investigated the effect of the visible section and the masking section’s ratio changing during the coincidence-anticipation timing task on the activity of the cerebral cortex. Subjects were eight healthy right-handed adult males. Subjects received the moving visual target with the stimulus runway visually masking (coincidence-anticipation timing tasks; the visible section: the masking section = 1 : 1, 1 : 2, 1 : 5) and, were asked to press the handheld pushbutton when the visual target arrived at an end each task. Electrodes were placed at 128 sites on the subjects’ scalp, and electroencephalograms (EEGs) were recorded during the coincidence-anticipation timing task. The EEGs were subjected to fast Fourier Transform in order to produce the power density in the beta (13-30 Hz) bands. The power in beta bands was expressed as a percentage of total power (3-30 Hz) in each task. The data were compared with each task.</p><p> The results showed that the percentage of beta band at 3-30 Hz increased significantly at the inferior frontal gyrus, the frontal pole, the middle temporal gyrus and the superior parietal lobules in the 1 : 1’s and the 1 : 2’s coincidence-anticipation timing task in the visible section compared with the 1 : 5’s coincidence-anticipation timing task. The results suggest that subjects during the 1 : 1’s and the 1 : 2’s coincidence-anticipation timing task in the visible section memorize shape and velocity of the moving visual target compared with the 1 : 5’s coincidence-anticipation timing task.</p>
