Bilateral ablation of auditory cortex in macaques results in both sensory and perceptual deficits. The sensory deficit is indicated by increased thresholds for left-right locus discriminations and an inability to discriminate locus within either the left of right hemifield. The perceptual deficit is indicated by the observation that the monkeys no longer appear to associate a sound with a location in space. Unilateral auditory cortex ablation results in an inability to discriminate locus within the hemifield contralateral to the lesion. It is not known whether unilateral lesions also result in a perceptual deficit.
对猕猴双侧听觉皮层进行切除会导致感觉和知觉缺陷。感觉缺陷表现为左右位置辨别阈值升高，且无法辨别左半视野或右半视野内的位置。知觉缺陷表现为观察到猴子似乎不再能将声音与空间中的位置联系起来。单侧听觉皮层切除会导致在与损伤对侧的半视野内无法辨别位置。目前尚不清楚单侧损伤是否也会导致知觉缺陷。
