After bilateral ablation of the auditory areas of the cerebral cortex, experimental animals have a severe deficit in ability to discriminate between temporal patterns of tonal stimuli and to localize sound in space. These two kinds of discrimination are basic for communication and for attack or avoidance of prey and predator. Recognition of which ear is stimulated may also depend upon excitation of auditory cortex contralateral to the given ear. Binaural discriminations are dependent upon interaction of nerve impulses from the two ears at a low level in the auditory nervous system. Similar hearing losses have been reported for human patients.
在双侧大脑皮层听觉区域被切除后，实验动物在辨别音调刺激的时间模式以及在空间中定位声音的能力方面存在严重缺陷。这两种辨别能力对于交流以及攻击或躲避猎物和捕食者来说至关重要。识别哪只耳朵受到刺激可能也取决于与给定耳朵对侧的听觉皮层的兴奋。双耳辨别依赖于来自两只耳朵的神经冲动在听觉神经系统较低水平的相互作用。人类患者也有类似的听力损失报告。
