被训练执行听觉和视觉短期记忆任务（延迟匹配样本）的猴子在颞上回的听觉关联皮层中受到损伤。虽然视觉记忆完全不受病变影响，但听觉记忆严重受损。尽管存在这种缺陷，所有的猴子都能分辨出比听觉记忆任务中使用的声音更接近频率的声音。这一结果表明，颞上皮层在听觉加工和记忆中的作用与颞下皮层在视觉加工和记忆中的作用相似。
Monkeys that were trained to perform auditory and visual short-term memory tasks (delayed matching-to-sample) received lesions of the auditory association cortex in the superior temporal gyrus. Although visual memory was completely unaffected by the lesions, auditory memory was severely impaired. Despite this impairment, all monkeys could discriminate sounds closer in frequency than those used in the auditory memory task. This result suggests that the superior temporal cortex plays a role in auditory processing and retention similar to the role the inferior temporal cortex plays in visual processing and retention.
