Abstract

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.
