Kleinbaum %A Thalia Wheatley %T Spontaneous Neural Encoding of Social Network Position %D 2017 %R 10.1101/098988 %J bioRxiv %P 098988 %X Humans form complex social networks that include numerous non-reproductive bonds with non-kin. Navigating these networks presents a considerable cognitive challenge thought to have comprised a driving force in human brain evolution. Yet, little is known about how and to what extent the human brain encodes the structure of the social networks in which it is embedded. By combining social network analysis and multi-voxel pattern analysis of functional magnetic resonance imaging (fMRI) data, we show that social network information about direct relationships, bonds between third parties, and aspects of the broader network topology is accurately perceived and automatically activated upon seeing a familiar other. %U https://www.biorxiv.org/content/biorxiv/early/2017/01/09/098988.full.pdf
