Researchers trained rats to perform timing tasks requiring precise 18-24 second intervals between lever presses for food rewards. When exposed to low-level microwave radiation (2.45 GHz pulsed at 1-5 mW/cm²), the sedative drug pentobarbital became significantly more potent, requiring 40% lower doses to produce the same behavioral effects. This demonstrates that microwave exposure can amplify drug effects in the brain.

Researchers exposed 24 pregnant rats to 2450 MHz microwave radiation (the same frequency as microwave ovens) for 8 hours daily throughout pregnancy at power levels that didn't raise body temperature. They found no significant effects on fetal development, birth outcomes, or behavioral development in offspring through two generations.

Researchers exposed Japanese quail embryos (8-13 days old) to 2450 MHz microwave radiation at various power levels to measure heart rate changes. Despite testing exposure levels from 0.3 to 30 mW/g using both pulsed and continuous waves, they found no effect on embryonic heart rate. The study confirmed that temperature changes affected heart rate, but the electromagnetic exposure itself did not.

Researchers exposed rats to intense 918 MHz microwave radiation for 30 minutes to see if it would help antibodies cross the blood-brain barrier to fight infections. The microwaves raised body temperature to dangerous levels but failed to allow antibodies into the cerebrospinal fluid.

Researchers exposed rats to strong 60 Hz electric fields (100 kV/m) for up to 30 days to test effects on reproduction and development. The study found no impacts on mating behavior, fertility, fetal development, or sperm quality. This suggests that extremely low frequency electric fields at these levels may not significantly harm reproductive health in mammals.
