"Interbrain neural synchrony is a new research area in neuroscience that explores the temporal and spatial coupling of the brain activity between communicating humans. Currently, the limited research has shown that interbrain synchrony is a positive predictor of efficient communication, and is enhanced by teamwork and leadership. Here, we aim to show that interbrain synchrony can be measured portably in natural environments using the MUSE EEG headband by replicating methods from a previous study (Fishburn et al., 2018)."
