Afferent Mechanisms of Microwave-Induced Biological Effects.

Abstract

We studied the effects of 2450MHz circularly polarized microwave irradiation on central nervous system functions. Pulsed (microsecond, 500 pps) microwaves decreased high affinity sodium-dependent choline uptake in the hippocampus and frontal cortex of the rat. The effect on hippocampal choline uptake was blocked by pretreatment with narcotic antagonists. Continuous-wave microwaves of the same power density decreased choline uptake in the frontal cortex only. Furthermore, we found that the effects of pulsed microwaves on central cholinergic activity are classically conditionable to cues in the exposure environment. The hypothesis that some of the neurological effects of pulsed microwave irradiation are caused by its effect on the auditory system was investigated. Effects of 'pink noise' and 'pulsed microwaves' were compared.
