Space-by-time decomposition of EEG data of an example subject. A) The three temporal components with consecutive peaks found by the scNM3F algorithm to describe the EEG data. B) The two spatial components: one comprises mainly occipital electrodes and the other mainly centro-frontal electrodes. C) The 6 (2 × 3) coefficients combining the three temporal with the two spatial components trial-averaged for each stimulus (face or car) and at each phase coherence level (20, 25, 30, 35, 40, and 45%).
