闪光诱发电位和背景脑电图记录从左，右颞叶和顶叶地区，而受试者进行口头和空间的任务。诱发电位功率和峰谷幅度的不对称性改变证实了脑电α功率的任务依赖性不对称性。EEG和诱发电位的不对称性措施反映了这些认知任务的半球专业化。
Flash evoked potentials and background EEG were recorded from left and right temporal and parietal areas while subjects performed verbal and spatial tasks. Changes in asymmetry of evoked potential power and peak-trough amplitudes paralleled the task-dependent asymmetry of the EEG alpha power. Both the EEG and evoked potential asymmetry measures reflected the hemispheric specialization for these cognitive tasks.
