Naive rhesus monkeys (Macaca mulatta) were trained preoperatively in an automated test apparatus on an auditory-visual (crossmodal) conditional task or on a visual-visual (intramodal) conditional task that involved learning a fixed set of stimulus-stimulus associations or paired associates. After having learned their respective tasks, each monkey received bilateral removal of the amygdala plus subjacent cortex. The 2 experimental groups showed equally poor retention of the stimulus-stimulus associations and subsequently relearned their respective crossmodal and intramodal associations at the same rate. These data argue against the idea that the amygdala is specialized for crossmodal associations. Instead, the data indicate that the amygdala or its underlying cortex, or both, play a more generalized role in stimulus-stimulus associative memory.
将新生恒河猴（猕猴）术前置于自动测试装置中，训练其完成听觉-视觉（跨模态）条件任务或视觉-视觉（模态内）条件任务，这些任务涉及学习一组固定的刺激-刺激关联或配对联想。在学会各自的任务后，每只猴子接受双侧杏仁核及相邻皮质切除术。两个实验组在刺激-刺激关联的记忆保持方面均表现不佳，随后以相同的速度重新学习各自的跨模态和模态内关联。这些数据反驳了杏仁核专门负责跨模态关联的观点。相反，数据表明杏仁核或其下层皮质，或两者在刺激-刺激联想记忆中发挥更广泛的作用。
