TL;DR
A method of charting the electrical fields at the surface of the head has been described which has proved useful in the localizing of EEG activity during sleep and a shift of focus of maximum activity from the parieto-occipital region when awake to the frontal lobes when asleep is described.
Abstract
(1) A method of charting the electrical fields at the surface of the head has been described which has proved useful in the localizing of EEG activity during sleep. (2) A shift of focus of maximum activity from the parieto-occipital region when awake to the frontal lobes when asleep has been described. (3) More than one focus, both of slow potentials and of spindles, have been demonstrated.
