> SUMMARY

> Recent well-documented research suggests that between 25% and 75% of human and animal subjects exhibit psychophysiological sensitivity to magnetic and electrical fields in the extreme low frequency (ELF) ranges corresponding to brainwave spectra.

> Neuronal synchronization/desynchronization and brainwave entrainment can be demonstrated clinically in cats, monkeys, and human sensitives in the presence of ELF oscillations of both natural and man-made signals, including pulse-modulated radio frequency carriers.

> There is additional evidence that the naturally-occurring earth-ionosphere cavity oscillations (known since 1952 as the "Schumann Resonance") can affect moods, states of consciousness, psychological stress, and health cycles of all life forms.

> Prior to 1975 or 1976, the Soviets began transmitting pulsed electromagnetic signals over broad frequency ranges (from approximately 4 MHz to beyond 18 MHz) of sufficient power levels (measured at 40 megawatts peak) to disrupt lawful radio communications globally.

> Fundamental frequencies of the higher harmonics as well as the pulse repetition rates (of 5 Hz to 15 Hz) of the Soviet EM transmissions fall precisely within the "window" of neuronal psychoactivity, and have been observed to alter human EEG traces.

> Speculation arises as to whether this potentially devastating problem is intentional or is an unfortunate side-effect of the Soviet's highly advanced global radar holographic imaging technology and undersea magnetic communications pulses.

> This personal communication is an overview of my investigation and discoveries in this area since 197O, a discussion of my instrumentation approaches, and projections for possible future research.

> A bibliography of pertinent references, articles, and books in the open literature is attached.

> I welcome feedback and communication from other interested researchers.
