INSTRUMENTATION FOR DETECTING, RECORDING, AND ANALYZING NATURAL AND MAN-MADE ELF SIGNALS AND HUMAN BRAINWAVES

ROBERT C. BECK · 1978

This 1978 technical report by Beck documented instrumentation methods for detecting and analyzing extremely low frequency (ELF) electromagnetic signals from both natural sources like lightning and man-made sources like power systems. The research also explored techniques for recording human brainwave patterns and their potential interactions with environmental ELF fields.

S. M. Bawin, W. R. Adey, I. M. Sabbot · 1978

Researchers exposed isolated chicken brain tissue to radiofrequency fields modulated at brain wave frequencies and found increased calcium release from cells. The calcium response depended on specific chemical conditions in the surrounding solution, particularly bicarbonate and hydrogen ion levels.

The Effects of Microwave Radiation on Microtubules and Axonal Transport

L-E. Paulsson, Y. Hamnerius, W. G. McLean · 1977

Researchers exposed rabbit brain tissue and nerve cells to 3.1 GHz pulsed microwave radiation to test whether it could damage microtubules, the cellular structures responsible for transporting materials within cells. They found no effects on microtubule function, protein binding, or nerve transport at power levels below 4,000 watts per square meter. This suggests that microwave radiation at typical environmental levels may not directly disrupt these fundamental cellular processes.

REGIONAL LEVELS OF CYCLIC AMP IN RAT BRAIN: PITFALLS OF MICROWAVE INACTIVATION

R. H. Lenox, J. L. Meyerhoff, O. P. Gandhi, H. L. Wray · 1977

Researchers tested how microwave radiation affects brain chemistry in rats, specifically measuring cyclic AMP levels in different brain regions. They found that microwave exposure altered brain metabolism at different rates depending on the brain region, with the hypothalamus, cortex, and cerebellum responding differently. The study highlighted technical challenges in controlling microwave exposure parameters for consistent results.
