【摘要】 ４０名正常被试在４场言语作业及２场非言语作业时记录脑电图，计算各场中１６个电极上δ、θ、αｌ、α２及β频带的功率值，与安静睁、闭眼时相应的功率值比较，以了解大脑各区的激活状况。结果表明言语或非言语作业均有大脑两半球的参与，言语作业时为左半球激活占优势，非言语视觉空间作业为右半球占优势。本研究支持汉字认知的左半球优势观点，也表明汉语认知是由左及右半球共同加工的。更多还原

【Abstract】 EEG were recorded during three verbal tasks and 3 non-verbal tasksin forty normal subjects,Delta,theta,alpha 1,alpha 2 and beta bands powers from sixteen electrodes were calculated in every task,then compared with the relevant band powers at openning eyes rest phase and closing eyes rest phase.The activated state of each cerebral area were found out.The results showed two hemispheres all taking part in verbal or non-verbal tasks,the activations on left hemispheres were dominated while verbal tasks,right hemisphere dominance was seen during non-verbal visuospatial task.This study agreed with the point of view that left hemisphere was dominated in Chinese Character cognition,also showed that Chinese words were elaborated together byleft and right hemispheres.更多还原
