From: Brain-to-brain entrainment: EEG interbrain synchronization while speaking and listening
Group-level statistical results from the multiple linear regression modelling analysis (full model) at the different frequency bands. The matrixes contain the coefficient estimates (R2 values) for a multilinear regression of the brain-to-brain entrainment response using as predictors the brain entrainment to speech of the listeners and the speakers. Statistically significant percentage of variance explained is indicated by coloring in green the corresponding cells where p < 0.05. Rows represent the electrodes of the Listener and columns represent the electrodes of the Speaker. Both brain-audio synchronizations were significant predictors of the brain-to-brain synchronization in all the analyzed frequency bands, being more generalized in the slow frequencies and mainly in those corresponding to theta.
