Dichotic listening scores and information on lesion size and location were obtained for aphasic patients. All patients had a reduction in dichotic scores at 1 month postonset of symptoms, but some patients returned to normal levels of performance by 6 months postonset. Lesion location was the main determinant of patterns of performance. Right ear scores from the dichotic digit test closely reflected the presence or absence of lesions involving Heschl's gyrus. What appeared to be an effect of lesion volume was confounded by the relationship between increasing lesion volume and a greater likelihood of damage to Heschl's gyrus.
我们获取了失语症患者的双耳分听分数以及病灶大小和位置的信息。所有患者在症状发作后1个月时双耳分听分数均有所下降，但部分患者在症状发作后6个月时恢复到了正常表现水平。病灶位置是表现模式的主要决定因素。双耳数字测试中的右耳分数密切反映了涉及颞横回的病灶的有无。病灶体积的影响似乎与病灶体积增加和颞横回受损可能性增大之间的关系相互混淆。
