Rhesus monkey behavior during exposure to high-peak-power 5.62-GHz microwave pulses.
D'Andrea JA, Thomas A, Hatcher DJ · 1994
Researchers exposed rhesus monkeys to high-power 5.62 GHz microwave pulses while the animals performed cognitive tasks for food rewards. At exposure levels of 4 and 6 watts per kilogram (W/kg), the monkeys showed significant impairments in their ability to respond correctly, with slower reaction times and fewer earned food rewards. This demonstrates that microwave radiation at these levels can disrupt cognitive performance and behavioral responses in real-time.
