Intensity Threshold for 60-Hz Magnetically Induced Behavioral Changes in Rats

Abstract

Experiments were conducted to further investigate the effect of 60-Hz cyclotron-resonance exposures on rats performing on a multiple FR-DRL schedule. The previously reported temporary loss of DRL baseline response, when measured as a function of A.C. magnetic intensity, was found to have a threshold. Utilizing the component of A.C. magnetic intensity parallel to the D.C. field, we report this threshold as (0.27 + or - 0.10) X 10-4 Trms. Keywords: Cyclotron resonance, Timing discrimination, A.C. threshold, DRL schedule, Electromagnetic radiation, Fixed ratio differential low rate (FR-DLR), Reprints.
