Three monkeys with extensive preoperative training on visual and auditory memory tasks (delayed matching-to-sample), an auditory pattern-discrimination task, and a visual serial-order task, received bilateral lesions of the superior temporal (ST) cortex in two stages, with testing after each lesion. Unilateral ST cortex lesions resulted in only moderate auditory memory impairments, whereas bilateral ST cortex lesions resulted in severe auditory memory impairments. The bilateral ST cortex lesions also resulted in severe impairments in the ability to relearn the auditory pattern-discrimination task. In contrast to the auditory impairments, neither unilateral nor bilateral ST cortex lesions had any effect whatsoever on either visual memory or visual serial-order behavior. These findings indicate that the ST cortex plays a role in auditory processing and retention similar to that played by the inferior temporal cortex for visual processing and retention.
三只猴子在视觉和听觉记忆任务（延迟匹配样本）、听觉模式辨别任务以及视觉序列任务方面接受了广泛的术前训练，分两个阶段接受了颞上（ST）皮质的双侧损伤，每次损伤后都进行测试。单侧ST皮质损伤仅导致中度听觉记忆障碍，而双侧ST皮质损伤则导致严重的听觉记忆障碍。双侧ST皮质损伤还导致重新学习听觉模式辨别任务的能力严重受损。与听觉障碍形成对比的是，单侧或双侧ST皮质损伤对视觉记忆或视觉序列行为均没有任何影响。这些发现表明，ST皮质在听觉处理和记忆方面所起的作用，类似于颞下皮质在视觉处理和记忆方面所起的作用。
