The capacity of auditory pathways from the weak ear (ear with the suppressed score in a dichotic listening test) to transmit speech information to the cortical processing areas was examined on 10 patients with unilateral temporal-lobe lesions. Three lines of evidence were developed to suggest that auditory pathways from the weak ear and speech information presented to the weak ear are not completely suppressed during dichotic stimulation. Speech in the weak ear frequently interacts with competing speech information in the strong ear causing contrasting articulatory features from the two ears to be blended into a single response. Two models of unilateral central auditory deficits are discussed: ipsilateral-suppression and transmission-line.
对10例单侧颞叶病变患者，研究了弱耳（在双耳分听测试中得分受抑制的耳朵）听觉通路向皮质处理区域传递语音信息的能力。有三条证据表明，在双耳分听刺激过程中，来自弱耳的听觉通路和呈现给弱耳的语音信息并未被完全抑制。弱耳中的语音经常与强耳中相互竞争的语音信息相互作用，导致来自两只耳朵的对比性发音特征混合成单一反应。讨论了两种单侧中枢听觉缺陷模型：同侧抑制和传输线模型。
