Abstract

Isolated frog nerves were exposed to 915 MHz pulse microwave radiation at a peak specific absorption rate (pSAR) of 5-70 kW/kg. Exposure induced non-thermal changes of nerve action potential amplitude and peak velocity: these changes exhibited different dependance on modulation parameters. The phasing of the microwave pulse with respect to nerve firing was not of particular importance. Within the studied range, both the effects didn´t correlate with the pSAR. The existence of two different mechanisms of non-thermal microwave effect on nerve function is supposed.
