群居动物可以通过多种形式的感官输入来识别同类。然而，支持这种识别个体能力的神经元计算是否依赖于模态无关的收敛或涉及沿着多个感觉流的持续协同相互作用仍然存在争议。直接测量相关大脑部位的神经元可以解决这些问题，但这需要更好地将人类和动物模型的工作联系起来。在这里，我们概述了最近在非人类灵长类动物中关于声音和面部身份敏感通路的研究，并评估了与人类相关发现的对应关系。这种综合提供了对灵长类动物前颞叶（ATL）中身份处理的聚合感觉流的见解。此外，我们提出了一个模型，并建议如何替代神经元机制可以测试。我们识别独特实体（如特定个体）的能力似乎依赖于前颞叶的感觉收敛。然而，颞叶前部感觉收敛的神经机制尚不清楚。其他说法仍然模棱两可，但可以通过更好地将人类和动物模型的发现联系起来进行测试。最近在猴子身上进行的面部和声音识别过程的研究，有助于缩小人类和动物模型研究之间的认知差距。我们综合了最近关于听觉和视觉识别相关过程在前颞叶的收敛的知识。这种综合在一个模型和对灵长类大脑中聚合感觉流的见解中达到高潮，并被用来建议如何测试识别个体的神经元机制。
Social animals can identify conspecifics by many forms of sensory input. However, whether the neuronal computations that support this ability to identify individuals rely on modality-independent convergence or involve ongoing synergistic interactions along the multiple sensory streams remains controversial. Direct neuronal measurements at relevant brain sites could address such questions, but this requires better bridging the work in humans and animal models. Here, we overview recent studies in nonhuman primates on voice and face identity-sensitive pathways and evaluate the correspondences to relevant findings in humans. This synthesis provides insights into converging sensory streams in the primate anterior temporal lobe (ATL) for identity processing. Furthermore, we advance a model and suggest how alternative neuronal mechanisms could be tested. Our ability to identify unique entities, such as specific individuals, appears to depend on sensory convergence in the anterior temporal lobe. However, the neural mechanisms of sensory convergence in the anterior temporal lobe are unclear. Alternative accounts remain equivocal but could be tested by better bridging the findings in humans and animal models. Recent work in monkeys on face- and voice-identity processes is helping to close epistemic gaps between studies in humans and animal models. We synthesize recent knowledge on the convergence of auditory and visual identity-related processes in the anterior temporal lobe. This synthesis culminates in a model and insights into converging sensory streams in the primate brain, and is used to suggest how the neuronal mechanisms for identifying individuals could be tested.
