我们在自然环境中听到的声音使我们能够识别声源并将其定位在空间中。这两个方面可以被破坏独立的15例局灶性右半球病变的研究中所示。四名患者的声音识别正常，但严重受损的声音定位，而其他三名患者有困难，识别声音，但本地化他们。选择性声音定位障碍患者病变累及顶叶下、额皮质和上级颞回;选择性识别障碍患者病变累及颞极和梭状回、颞中回和颞下回前部。这些结果表明，单独的皮层处理听觉识别和定位的途径。
A sound that we hear in a natural setting allows us to identify the sound source and localize it in space. The two aspects can be disrupted independently as shown in a study of 15 patients with focal right-hemispheric lesions. Four patients were normal in sound recognition but severely impaired in sound localization, whereas three other patients had difficulties in recognizing sounds but localized them well. The lesions involved the inferior parietal and frontal cortices, and the superior temporal gyrus in patients with selective sound localization deficit; and the temporal pole and anterior part of the fusiform, inferior and middle temporal gyri in patients with selective recognition deficit. These results suggest separate cortical processing pathways for auditory recognition and localization.
