Spectral Power Densities (SPD) within the Quantitative Electroencephalographic (QEEGs) Profiles of 41 men and women displayed repeated transient coherence with the first three modes (7 -8 Hz, 13 -14 Hz, and 19 -20 Hz) of the Schumann Resonance in real time. The duration of the coherence was about 300 ms about twice per min. Topographical map clusters indicated that the domain of maximum coherence was within the right caudal hemisphere near the Parahippocampal gyrus. These clusters, associated with shifts of about 2 μV, became stable about 35 to 45 ms after the onset of the synchronizing event. During the first 10 to 20 ms, the isoelectric lines shifted from clockwise to counterclockwise rotation. The results are consistent with the congruence of the frequency, magnetic field intensity, voltage gradient, and phase shifts that are shared by the human brain and the earth-ionospheric spherical wave guide. Calculations indicated that under certain conditions interactive information processing might occur for brief periods. Natural and technology-based variables affecting the Schumann parameters might be reflected in human brain activity, including modifications of cognition and dream-related memory consolidation.
