Abstract

We have found that two important brain synaptic receptor systems are very sensitive to the influence of low intensity microwaves. Both the excitatory glutamatergic and the inhibitory GABAergic are affected by microwave exposure. Power densities higher 50 microW/cm2 caused changes in the binding properties of these receptors to agonists. Low frequence modulation of microwaves was essential for these effects. Statistically significant effects on mean value of binding were observed at 16 Hz modulation. Exposure to microwave radiation changes the binding of agonists to glutamate and GABA receptors in different ways. An increase was observed for glutamate and a decrease for GABA. We suppose that the effect of microwaves is related to the stress reactions of the organism.

Main findings

Low-intensity microwave exposure was reported to alter agonist binding to brain glutamate and GABA receptors when power density exceeded 50 microW/cm2. Effects were described as dependent on low-frequency modulation, with statistically significant changes in mean binding observed at 16 Hz modulation; glutamate binding increased while GABA binding decreased.
