Abstract

A computerised evoked potential test for the lateralisation of speech dominance was compared with the intracarotid sodium amylobarbitone test in 22 epileptic patients. Based on spectral analysis, the computer test correctly predicted the speech dominance of 15 of 16 left speech dominant and five of six right speech dominant patients. This non-invasive test is simple, quick, and innocuous and can be easily implemented on a small laboratory computer.

摘要

对22例癫痫患者进行了一项用于言语优势半球定位的计算机诱发电位测试,并与颈内动脉注射异戊巴比妥钠测试进行了比较。基于频谱分析,计算机测试正确预测了16例左侧言语优势患者中的15例以及6例右侧言语优势患者中的5例的言语优势半球。这项非侵入性测试简单、快速且无害,并且可以很容易地在小型实验室计算机上实施。
