This field started for me in 1987 with a bioelectromagnetics instrument design portfolio that eventually comprised AC and DC gaussmeters, geomagnetometers, electrostatic and ion current meters, ELF spectrum analyzers, and a Dental Vapor Ionizer. I was privileged to exchange viewpoints with Dr. Robert O. Becker about the possibility of measuring a brain’s magnetoencephalogram (MEG) with off-the-shelf high-gain amplifier chips and of course, the effect of the earth’s Schumann resonance on brain waves
