Abstract Hyperscanning is a method thanks to which two or more subjects can mutually interact while their brains are simultaneously scanned by means of multiple, simultaneous EEG, allowing the study of the brain responses that determine important social interactions. The types of interactions that can be studied are diverse, ranging from competitive games, to cooperative tasks or musical performances. The objective of this thesis was to design and build a low-cost, open-source, wireless platform for multi-nodal time-synchronized EEG recording (hyperscanning): the time-synchronization has been achieved via the network clock from a WiFi network. The system is composed by different devices interconnected, both hardware and software.
