Abstract
The effects of various psychoactive drugs were studied in rats exposed for 45 min in a circularly polarized, pulsed microwave field (2450 MHz; SAR 0.6 W/kg; 2‐μs pulses, 500 pps). Apomorphine‐induced hypothermia and stereotypy were enhanced by irradiation. Amphetamine‐induced hyperthermia was attenuated while stereotypy was unaffected. Morphine‐induced catalepsy and lethality were enhanced by irradiation at certain dosages of the drug. Since these drugs have different modes of action on central neural mechanisms and the effects of microwaves depend on the particular drug studied, these results show the complex nature of the effect of microwave irradiation on brain functions.
