Changes in alpha activity induced by hand movements, both ipsi and contralateral to left brain hemisphere were studied. Seven channels of EEG (F3, C3, P3, O1, T3, T5 and CZ referred to nasion) were processed by a minicomputer. The values which correspond to three tasks (rest, right hand and left hand movement) were analyzed by means of an ANOVA of three factors. Our data bring us to the following conclusions: The two movements (left and right hand) cannot be differentiated by alpha band power in any electrode position and both of them decrease the alpha power significantly. This decreasing effect is not homogeneous in the whole hemisphere, being greater in the central area.
研究了左脑半球同侧和对侧手部运动引起的α活动变化。通过小型计算机处理脑电图的七个通道（F3、C3、P3、O1、T3、T5和以鼻根为参照的CZ）。对应于三项任务（休息、右手运动和左手运动）的值通过三因素方差分析进行分析。我们的数据得出以下结论：在任何电极位置，两种运动（左手和右手）都不能通过α波段功率进行区分，并且两者都会显著降低α功率。这种降低效应在整个半球并不均匀，在中央区域更大。
