Abstract
<p> In the present study, we attempted to clarify the brain activity during timely reaction and non-timely reaction by using coincidence-anticipation timing tasks that involved a downward moving visual target. The subjects were ten, healthy, right-handed adults. The tasks were displayed on a computer screen. Electrodes were placed at 128 sites on the subjects' scalp, and electroencephalograms (EEGs) were recorded. The EEGs were analyzed by fast Fourier Transform (FFT) analysis, and the percentage of beta band (13-30 Hz) at 3-30 Hz was derived from FFT analysis for each visible section, first half of the masking section and second half of the masking section. The data were divided into timely reaction and non-timely reaction groups, and the outcomes for the three sections were compared between the groups by analysis of variance. </p><p> The results showed that the percentage of beta band at 3-30 Hz increased significantly at the central region in the first half of the masking section, and at the posterotemporal's in the second half of the task. The results suggested that in the first half of the masking section, the central region activity contributed to the translation of visual information to movement prediction of visual target and in the second half of the task, error in visual information and movement prediction of visual target measurement by posterotemporal's activity in order to timely reaction in a coincidence-anticipation timing task using a downward moving visual target.</p>
