[Effect of SHF-radiation on spontaneous impulse activity of cerebral cortex slices in vitro]

The effect of microwaves field (900 MHz), pulse modulated at frequencies of 7, 16 and 30 Hz, on spontaneous electrical activity (SEA) of cerebral cortex slices of guinea-pig has been studied. Microwaves were shown to induce an irreversible decrease in repetitive rate of SEA. Conventional heating with the temperature rise above that during irradiation produced the same but reversible effect. It is suggested that the microwave effect on SEA is complex consisting of thermal and athermal components.
