We employ cortical mesoscale calcium-imaging to observe brain activity in two head-fixed mice in a staged social touch-like interaction. Using a rail system, mice are brought together to a distance where macrovibrissae of each mouse make contact. Cortical signals were recorded from both mice simultaneously before, during, and after the social contact period. When the mice were together, we observed bouts of mutual whisking and cross-mouse correlated cortical activity in the vibrissae cortex. This correlated activity was specific to individual interactions as the correlations fell in trial-shuffled mouse pairs. Whisk-related global GCAMP6s signals were greater in cagemate pairs during the together period. The effects of social interaction extend outside of regions associated with mutual touch and had global synchronizing effects on cortical activity. We present an open-source platform to investigate the neurobiology of social interaction by including mechanical drawings, protocols, and software necessary for others to extend this work.
