OBJECTIVES The quadratic phase-coupling (QPC) within burst patterns during electroencephalic burst suppression has been quantified. METHODS It can be shown that a QPC exists between the frequency ranges 0-2.5 and 3-7.5 Hz and between the frequency ranges 0-2.5 and 8-12 Hz. By means of time-variant bicoherence analysis, a strong phase-locking between the modulating and the modulated component can be identified. The phase-locking is demonstrable within the first 250 ms after the burst onset and… CONTINUE READING
