Normative standard of modulation index (MI) during interictal slow-wave sleep. (A) The locations of spatially-normalized non-epileptic electrode sites of 47 patients used to generate this normative atlas showing the topography of phase-amplitude coupling between the HFA > 150 Hz amplitude and the phase of local slow wave 3–4 Hz. (B) Mean across 30 closest sites. (C) Standard deviation across 30 closest sites.
