[Action of microwaves with different modulation frequencies and exposure times on GABA receptor concentration in the cerebral cortex of rats].

The effect of 800 mHz microwaves of 0, 3, 5, 7, 16, and 30 Hz modulation on GABA receptor concentration in rat brain cortex has been investigated. Irradiation of the whole body at a modulation frequency of 16 Hz readily decreases the GABA receptor concentration. Irradiation at other modulation frequencies is ineffective. Irradiation of the whole body modulated at 16 Hz with various exposure times (5, 15 and 60 min) has revealed the highest effect at 5 min, while at a longer exposure the effect decreases.
