A dichotic listening test was administered to 28 patients with lacunar syndromes in order to contribute to the investigation of the subcortical route of interhemispheric auditory pathways. Topographic study showed that lesions in the external capsule or in the anterior limb of the internal capsule in both hemispheres produced left ear extinction. The possibility that some of the auditory fibres travel through the external capsule, as well as the anterior limb of the internal capsule, before crossing the contralateral cerebral lobe is suggested.
对28例腔隙综合征患者进行了双耳分听测试，以促进对半球间听觉通路皮质下途径的研究。地形图研究表明，双侧外囊或内囊前肢的病变会导致左耳听觉消失。这表明一些听觉纤维可能在穿过对侧脑叶之前，先通过外囊以及内囊前肢。
