Researchers exposed monkeys to extremely high-intensity ultrawideband electromagnetic radiation (250,000 volts per meter) for 2 minutes and tested their ability to perform a balance task requiring precise motor control. The monkeys showed no changes in their performance immediately after exposure. This suggests that even very intense short-term EMF exposure may not cause immediate behavioral disruption in primates.

Chinese researchers exposed rats to electromagnetic pulse (EMP) radiation and found it caused brain damage, including neuronal death and learning problems. When they treated the rats with sevoflurane (an anesthetic gas), it protected against this brain damage by reducing oxidative stress and preventing brain cell death. This suggests that electromagnetic pulses can harm brain function, but also that protective treatments might be possible.

Researchers exposed mice to intense electromagnetic pulses (400,000 volts per meter) and found it significantly impaired their ability to learn new tasks for up to 24 hours. The exposure caused oxidative stress in brain tissue, damaging brain cells through increased harmful molecules and reduced protective antioxidants. When mice were given vitamin E beforehand, it protected them from these harmful effects.

Researchers used computer simulations to study how 2.45 GHz microwave radiation (the same frequency used in WiFi and microwave ovens) affects protein structure at the molecular level. They found that electromagnetic fields disrupted the normal folding patterns of proteins by interfering with hydrogen bonds that keep proteins stable. This suggests that microwave radiation can alter fundamental biological processes by changing how proteins maintain their shape and function.
