Investigation of radiofrequency/microwave effects upon the central nervous system. Final report
A study to determine the effect of pulsed electromagnetic energy upon brain calcium behavior was undertaken. An innovative approach for loading the cerebral tissues with radiocalcium was introduced. Intraventricular injections through the skull placed Ca-45 solution directly into the right lateral ventricle. Two hours later, companion frontal lobe samples were placed in separate glass breakers containing physiologic solution for a 20-min exposure to pulsed electromagnetic energy. An efflux value was calculated for each sample. A second experimental procedure involved whole-body irradiation of the animals two hours following the intraventricular injections. Animals were then irradiated with pulsed electromagnetic energy at a power density of 10 mW/cm squared, a pulse repetition frequency of 16 Hz, and carrier frequency of 2.45 GHz. Following exposure, frontal lobe and parieto-occipital tissue samples were taken and analysed for radioactivity. Statistical treatment of the first sets of experiments failed to reveal any perturbation in calcium efflux behavior. Data from the second set are still being evaluated.
