Phase shift invariant imaging of coherent sources (PSIICOS) from MEG data

Alex Ossadtchi, Dmitrii Altukhov, Karim Jerbi

Abstract: Highlights•Novel framework for linear functional coupling estimation.•Suppresses spatial leakage and yet keeps zero-phase lag coupling detectable.•Yields uniform performance over the entire range of phase lags.•Renders coupling detection task as a source estimation problem but in hyper-space.•May add robustness to functional coupling studies and welcomes priors.
