In a group of normal adults, averaged cortical evoked responses to natural speech stimuli were recorded from scalp electrodes placed symmetrically over the two cerebral hemispheres at frontal, Rolandic, and temporoparietal leads. The amplitude of the most prominent component was consistently larger in left hemisphere derivations, with the major hemisphere difference observed in the temporoparietal records. These electrophysiological measures may be sensitive indicators of hemispheric specialization of function.
在一组正常成年人中,通过放置在两个大脑半球额叶、中央沟和颞顶叶导联上对称的头皮电极记录了对自然语音刺激的平均皮层诱发反应。最突出成分的振幅在左半球导联中始终较大,主要的半球差异出现在颞顶叶记录中。这些电生理测量可能是功能半球特化的敏感指标。
