Comparing the neural correlates of socio-cognitive skills across species provides insights into the evolution of the social brain and has revealed face- and body-sensitive regions in the primate temporal lobe. Although from a different lineage, dogs share convergent visuo-cognitive skills with humans and a temporal lobe which evolved independently in carnivorans. We investigated the neural correlates of face and body perception in dogs (N = 15) and humans (N = 40) using functional MRI. Combining univariate and multivariate analysis approaches, we found functionally analogous occipito-temporal regions involved in the perception of animate entities and bodies in both species and face-sensitive regions in humans. Though unpredicted, we also observed neural representations of faces compared to inanimate objects, and dog compared to human bodies in dog olfactory regions. These findings shed light on the evolutionary foundations of human and dog social cognition and the predominant role of the temporal lobe.
比较跨物种的社会认知技能的神经相关性可以深入了解社会大脑的进化,并揭示了灵长类动物颞叶中的面孔和身体敏感区域。尽管来自不同的谱系,但狗与人类具有趋同的视觉认知技能,并且在食肉动物中独立进化的颞叶。我们使用功能磁共振成像研究了狗(N=15)和人类(N=40)对面部和身体感知的神经相关性。通过结合单变量和多变量分析方法,我们发现两种物种的颞叶中存在功能相似的枕颞区域,这些区域参与了对有生命实体和身体的感知,并且在人类中存在面孔敏感区域。尽管出人意料,但我们还观察到了狗嗅觉区域中相对于无生命物体和狗相对于人体的面孔神经表示。这些发现揭示了人类和狗社会认知的进化基础以及颞叶的主要作用。
