Biological Windows /
The term "Biological windows" comes from the Californian neurologist William Ross Adey. He was able to demonstrate from the calcium efflux from rabbits brain cells, that this effect can only be triggered off with certain magnetic field intensity.
With "biological windows" you describe an intensity and frequency area which the cellular tissue is especially receptive to. This corresponds to certain cell receptors which can only react to defined frequencies. Subsequently this "resonance effect" enhances or unblocks natural signals, which are indispensable for metabolic processes, circulation, cell renewal, creating energy or for the immune defence systems.
