Nature seems to have figured out that electric fields, similar to the role they play in human-created machines, can power a wide array of processes essential to life. Perhaps even consciousness itself. A veritable army of neuroscientists and electrophysiologists around the world are developing steadily deeper insights into the degree that electric and magnetic fields—“brainwaves” or “neural oscillations”—seem to reveal key aspects of consciousness. The prevailing view for some time now has been that the brain’s bioelectric fields, which are electrical and magnetic fields produced at various physical scales, are an interesting side effect—or epiphenomenon—of the brains’ activity, but not necessarily relevant to the functioning of consciousness itself.
