A dichotic monitoring test for the lateralisation of speech dominance was compared with testing for dysphasia after unilateral electroconvulsive therapy to each side of the head in 31 patients, and the intracarotid amylobarbitone test in four epileptic patients. Twenty-eight patients shown to be left speech dominant also showed right ear advantages in the dichotic test. Four of the five right speech dominant patients showed left ear advantages. Two patients with bilateral speech representation showed nonsignificant ear asymmetries. The noninvasive dichotic monitoring task is quick and simple and produces large mean ear advantages (14 to 25%) in normal subjects as well as patients.
对31例患者进行了用于言语优势半球定位的双耳分听监测测试,并与单侧头部电惊厥治疗后进行的言语障碍测试以及4例癫痫患者的颈动脉内异戊巴比妥测试进行了比较。28例显示为左侧言语优势的患者在双耳分听测试中也表现出右耳优势。5例右侧言语优势患者中有4例表现出左耳优势。2例具有双侧言语表征的患者显示出无显著意义的耳不对称。这种非侵入性的双耳分听监测任务快速、简单,在正常受试者和患者中均产生较大的平均耳优势(14%至25%)。
