非人灵长类动物产生多种物种特异性呼叫，并具有丰富的概念系统。它们的一些叫声是为了传达有关捕食者、食物和社会关系等概念的信息，以及呼叫者的情感状态。人们对这些叫声的神经结构知之甚少，我们所知道的大部分都是基于麻醉受试者的单细胞生理学。通过对清醒的恒河猴进行正电子发射断层扫描，我们发现同种发声引起了高阶视觉区的活动，包括颞叶中与物体形状视觉感知（TE/TEO）和运动相关的区域（上级颞沟）并将视觉对象信息存储到长期记忆（TE）中，以及边缘系统（杏仁核和海马体）和边缘系统区域（腹内侧前额叶皮层），这些区域与高度显著和情感材料的解释和记忆编码有关。这种神经回路强烈对应于支持人类同种和情感信息表示的网络。这些发现揭示了人类概念表征的进化前体，表明猴子和人类有一个共同的神经基质来表征物体概念。
Non-human primates produce a diverse repertoire of species-specific calls and have rich conceptual systems. Some of their calls are designed to convey information about concepts such as predators, food, and social relationships, as well as the affective state of the caller. Little is known about the neural architecture of these calls, and much of what we do know is based on single-cell physiology from anesthetized subjects. By using positron emission tomography in awake rhesus macaques, we found that conspecific vocalizations elicited activity in higher-order visual areas, including regions in the temporal lobe associated with the visual perception of object form (TE/TEO) and motion (superior temporal sulcus) and storing visual object information into long-term memory (TE), as well as in limbic (the amygdala and hippocampus) and paralimbic regions (ventromedial prefrontal cortex) associated with the interpretation and memory-encoding of highly salient and affective material. This neural circuitry strongly corresponds to the network shown to support representation of conspecifics and affective information in humans. These findings shed light on the evolutionary precursors of conceptual representation in humans, suggesting that monkeys and humans have a common neural substrate for representing object concepts.
