RT Journal Article SR Electronic T1 Spontaneous Neural Encoding of Social Network Position JF bioRxiv FD Cold Spring Harbor Laboratory SP 098988 DO 10.1101/098988 A1 Carolyn M. Parkinson A1 Adam M. Kleinbaum A1 Thalia Wheatley YR 2017 UL http://biorxiv.org/content/early/2017/01/09/098988.abstract AB 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.
