An Evaluation of Possible Effects of 45 Hz, 60 Hz and 75 Hz Electric Fields on Neurophysiology and Behavior of Monkeys. Phase I: Continuous Wave.
Abstract
Five monkeys were well trained on a Skinnerian schedule in which a five sec interval between responses was reinforced. After a stable level of responding had been achieved, monkeys were exposed to a random series of several electric field configurations with frequencies of 7 Hz, 45 Hz, 60 Hz or 75 Hz and with voltage levels of 1, 10, 56 or 100 V/m p-p. At 1 V/m p-p there was no discernible effect on either behavior or electrical brain waves. (This is approximately 5 times the voltage associated with Project Sanguine.) At 10 V/m there was evidence for a frequency-specific threshold at 7 Hz. Time between responses (interresponse times) was significantly shorter and variability of responding was reduced. When voltage was increased to 56 V/m direction of the effect was the same as at 10 V/m and the magnitude of the change was markedly increased for both 7 Hz and 75 Hz fields. At 100 V/m there was some evidence for a carry-over effect from one day to the next.
