Jacobson resonance, a general form of Zeeman and cyclotron resonance, is proposed as a fundamental explanation relating to the effects of non-ionizing radiation on biological systems. The foundation of the mathematical perspective is presented. This theoretical model predicts the clinical efficacy of picoTesla magnetic fields in the treatment of neurological disorders. Recent clinical data is presented and analyzed. Additionally, recent experimental data concerning important biological frequency and amplitude windows is explained. More particularly, 16 Hz, 60 Hz, and 72 Hz windows are related to milliGauss magnetic fields and space fields.
