Event-Related Potentials were recorded over occipital and parietal scalp from left- and right-handed adults presented with a language and a non-language visual stimulus using a divided field, "oddball" paradigm. The major finding of interest was that the P300 component was larger over the left than the right hemisphere of the right-handers when the language stimulus was presented to the left hemisphere; there were no hemispheric differences for the left-handers, regardless of field of presentation. These results are discussed in the context of developing noninvasive measures to lateralize language function.
使用分离视野“oddball”范式，对左利手和右利手成年人在呈现语言和非语言视觉刺激时，记录枕叶和顶叶头皮上的事件相关电位。主要感兴趣的发现是，当语言刺激呈现给左半球时，右利手者左半球的P300成分比右半球大；左利手者无论刺激呈现的视野如何，均无半球差异。本文在开发语言功能脑区定位非侵入性测量方法的背景下讨论了这些结果。
