灵长类认知需要互动处理。相互作用可以揭示意图主体的其他隐藏属性,如思想和感受,以及无生命物体的属性,如质量和材料。交互分析在大脑中的何处以及如何实现尚不清楚。利用猕猴的全脑功能磁共振成像,我们发现了一个集中在内侧和腹外侧前额叶皮层的网络,专门从事社会互动分析。专门化的排他性被发现在大脑的任何地方都没有其他功能。另外两个网络,一个parieto-premotor和一个temporal的,表现出社会和身体的互动偏好,其中,在颞叶,映射到一个细粒度的模式的对象,身体和面部的选择性。社会互动分析专用系统的范围和位置表明,这种功能是人类读心能力的进化先驱。
Primate cognition requires interaction processing. Interactions can reveal otherwise hidden properties of intentional agents, such as thoughts and feelings, and of inanimate objects, such as mass and material. Where and how interaction analyses are implemented in the brain is unknown. Using whole-brain functional magnetic resonance imaging in macaque monkeys, we discovered a network centered in the medial and ventrolateral prefrontal cortex that is exclusively engaged in social interaction analysis. Exclusivity of specialization was found for no other function anywhere in the brain. Two additional networks, a parieto-premotor and a temporal one, exhibited both social and physical interaction preference, which, in the temporal lobe, mapped onto a fine-grain pattern of object, body, and face selectivity. Extent and location of a dedicated system for social interaction analysis suggest that this function is an evolutionary forerunner of human mind-reading capabilities.
