Unmixing Oscillatory Brain Activity by EEG Source Localization and Empirical Mode Decomposition

Subject 1: significant clusters from a temporal cluster permutation test, source-level. The circular-linear correlation across trials was calculated between the MEP response and the phase of the extracted components in four frequency bands. The components were extracted from the source having highest power in the LPG. The locations of this source across trials are indicated in the inset. Light red: few trials having highest power here; dark red: most trials having highest power here. (a) θ (4–8 Hz). (b) α (8–14 Hz). (c) β₁ (14–22 Hz). (d) β₂ (22–30 Hz).
