WebBy using high-spatial resolution EEG we developed sleep maps for the first two decades of life. Our research revealed that the deep-sleep marker, slow wave activity (SWA, 1-4.5 Hz) undergoes a posterior- to-anterior shift in its location on the scalp. This pattern closely parallels cortical anatomical maturation and associated brain functions.
