Researchers exposed 15 healthy people to pulsed magnetic fields (920 Hz) while measuring brain glucose metabolism using PET scans. They found that areas of the brain exposed to stronger electric fields showed decreased metabolic activity compared to unexposed areas. The stronger the field, the greater the reduction in brain metabolism, suggesting that electromagnetic fields can directly alter brain function.

Researchers exposed rats to WiFi-frequency radiation for 30 minutes and found increased heat shock proteins in brain regions controlling hormones and sensory processing. These proteins indicate cellular stress, with effects lasting 24 hours, suggesting brief microwave exposure triggers brain stress responses.

Finnish researchers tested whether 50 Hz magnetic fields (the type from power lines) could amplify DNA damage from UV radiation in mouse cells. They exposed cells to magnetic fields of 100-300 microTesla during or before UV exposure and measured cellular oxidative stress. The study found no evidence that magnetic fields increased UV-induced damage, contradicting their hypothesis about how magnetic fields might affect cellular chemistry.
Lu ST et al. · 2010
Researchers exposed four rhesus monkeys to intense 2.8 GHz microwave radiation for 36 hours total over three weeks and measured any damage to the corneal endothelium (the inner layer of cells in the eye's cornea). The study found no changes in corneal cell density or thickness, even at power levels more than ten times higher than previous studies that reported eye damage. This suggests that microwave exposure at these levels may not harm this specific part of the eye.
Parazzini M et al. · 2010
Researchers exposed 73 healthy adults to 3G cell phone radiation (UMTS) at 1.75 W/kg SAR for 20 minutes and tested their hearing function before and after exposure. They found no measurable effects on hearing thresholds, inner ear function, or brain responses to sound. This suggests that short-term exposure to 3G radiation at levels similar to heavy phone use doesn't immediately damage the auditory system.
Takahashi S et al. · 2010
Researchers exposed pregnant rats to 2.14 GHz radiofrequency radiation (similar to cell tower signals) for 20 hours daily throughout pregnancy and nursing. They found no harmful effects on the mothers, their offspring, or the next generation, examining everything from growth and development to memory and reproductive function. This suggests that exposure levels similar to those from cell towers may not cause developmental problems in mammals.

Researchers measured how tissue properties change with age in pigs and used this data to calculate radiation absorption (SAR) in children using walkie-talkies. They found that while tissue properties do change significantly with age - mainly due to decreasing water content - these changes don't meaningfully affect how much radiation children absorb compared to adults when using walkie-talkie devices.
Di Loreto S et al. · 2009
Researchers exposed rat brain cells to 50 Hz magnetic fields and found the exposure improved cell survival and reduced cell death. The magnetic fields also triggered protective antioxidant responses and increased production of proteins that support brain health, suggesting potential protective effects.
Reba Goodman et al. · 2009
Researchers exposed flatworms (planaria) to 60 Hz magnetic fields at 80 milliGauss for one hour twice daily during regeneration after being cut in half. The EMF-exposed worms regenerated faster than unexposed controls, with tail portions growing eyes 48 hours earlier and showing increased levels of stress proteins typically associated with healing and repair processes.
Sommer et al. · 2009
Researchers exposed mice to cell phone radiation (UMTS signals at 1966 MHz) continuously for their entire lives across four generations to study effects on reproduction and development. They found no harmful effects on fertility, pup development, or reproductive health, even at exposure levels up to 1.3 W/kg SAR. The only minor finding was some changes in food consumption patterns without a clear dose-response relationship.
Furubayashi T et al. · 2009
Japanese researchers exposed 54 women to cell tower-like radio waves for 30 minutes to test whether people who report mobile phone sensitivity can actually detect electromagnetic fields. They found that sensitive individuals couldn't tell when they were being exposed any better than control subjects, but they consistently reported more discomfort regardless of whether the EMF was on or off. This suggests that electromagnetic hypersensitivity symptoms aren't directly caused by the radio waves themselves.
Furubayashi T et al. · 2009
Researchers exposed 54 women (including 11 with self-reported electromagnetic hypersensitivity) to cell tower radiation at 10 V/m for 30 minutes in a controlled lab setting. Neither group could detect when they were actually being exposed to EMF, and both groups showed identical biological responses whether exposed to real or fake radiation. The study found no evidence that people with electromagnetic hypersensitivity react differently to cell tower emissions than healthy controls.
Naziroğlu M, Gümral N. · 2009
Researchers exposed rats to WiFi-frequency radiation (2.45 GHz) for one hour daily over four weeks. The radiation significantly reduced protective antioxidant vitamins A, C, and E in brain tissue. This suggests wireless devices may deplete the brain's natural defenses against cellular damage.
Naziroğlu M, Gümral N. · 2009
Researchers exposed rats to 2.45 GHz radiation (the same frequency used in WiFi and microwaves) for one hour daily over 28 days and found it depleted protective antioxidant vitamins in brain tissue. When rats were given selenium or L-carnitine supplements, these nutrients helped protect against the radiation-induced vitamin depletion. This suggests that WiFi-frequency radiation creates oxidative stress in the brain that may be partially countered by certain antioxidant supplements.
Naziroğlu M, Gümral N · 2009
Turkish researchers exposed rats to WiFi-frequency radiation (2.45 GHz) for one hour daily over 28 days and found it depleted key brain antioxidants including vitamins A, C, and E. When rats were given selenium or L-carnitine supplements during exposure, these protective nutrients were largely restored, with L-carnitine showing stronger protective effects. This suggests that wireless device radiation creates oxidative stress in brain tissue, but certain antioxidants may help counteract this damage.
Cook CM, Saucier DM, Thomas AW, Prato FS. · 2009
Researchers exposed 32 people to weak pulsed magnetic fields (the type generated by power lines and electrical devices) for 15 minutes while measuring their brain waves. They found that different pulse patterns altered alpha brain wave activity in the back regions of the brain within just 5 minutes of exposure. The changes persisted even after exposure ended, suggesting that these everyday magnetic fields can measurably affect brain function.
Ogawa K et al. · 2009
Researchers exposed pregnant rats to cell phone radiation (1.95-GHz W-CDMA signals) for 90 minutes daily during the critical period of fetal development (days 7-17 of pregnancy). They found no harmful effects on pregnancy outcomes, fetal development, or birth defects at exposure levels up to 2.0 W/kg brain SAR. This suggests that typical cell phone radiation exposure during pregnancy may not cause developmental problems in offspring.
Ogawa K et al. · 2009
Researchers exposed pregnant rats to cell phone radiation (1.95-GHz signals) for 90 minutes daily during pregnancy to see if it would harm developing babies. They tested different exposure levels, including some higher than typical cell phone use, and found no effects on pregnancy outcomes, fetal development, or birth defects. The study suggests that cell phone radiation at these levels doesn't appear to cause developmental problems during pregnancy.
Eltiti S et al. · 2009
Researchers exposed 88 people (including those who claimed to be sensitive to electromagnetic fields) to cell tower signals for 50 minutes while they performed memory and attention tests. The study found no effects on cognitive performance or physiological measures like heart rate and skin conductance in either sensitive or control participants. This suggests that short-term exposure to typical cell tower radiation levels doesn't impair brain function or cause detectable physical responses.

Researchers exposed guinea pigs to 50 Hz magnetic fields (power line frequency) for four hours daily over four days. Both continuous and pulsed exposures increased cellular damage markers in blood, liver, and brain tissue, suggesting power-frequency fields can trigger harmful oxidative stress.
Varró P, Szemerszky R, Bárdos G, Világi I. · 2009
Researchers exposed rat brain tissue to 50 Hz magnetic fields at levels commonly found near power lines (250-500 microtesla) and measured changes in brain cell communication. They found that direct exposure reduced normal brain signaling, while whole-body exposure increased seizure susceptibility and altered how brain cells strengthen their connections. These findings suggest that everyday electromagnetic fields from electrical infrastructure can measurably alter fundamental brain functions.
Coşkun S, Balabanli B, Canseven A, Seyhan N. · 2009
Researchers exposed guinea pigs to 50 Hz magnetic fields (like power lines) for four hours daily over four days. Both continuous and intermittent exposure increased cellular damage in blood, liver, and brain tissue, showing that even brief magnetic field exposure can trigger harmful stress responses throughout the body.
Varró P, Szemerszky R, Bárdos G, Világi I. · 2009
Researchers exposed rat brain tissue to 50 Hz magnetic fields at power line levels. The exposure altered how brain cells communicate and increased seizure-like activity. This suggests electromagnetic fields from power infrastructure may affect brain function, though effects appeared temporary.
Dimbylow PJ, Nagaoka T, Xu XG. · 2009
Scientists studied how radio waves from cell phones and WiFi affect unborn babies at different pregnancy stages using computer models. They found radiation absorption varies significantly based on the baby's development stage and wave direction, helping establish safety guidelines for pregnant women.
Cvetkovic D, Cosic I. · 2009
Researchers exposed 33 people to extremely low frequency magnetic fields at different frequencies (4-50 Hz) for 2 minutes each and measured their brain waves using EEG. They found that magnetic fields at specific frequencies could synchronize with and alter corresponding brain wave patterns, particularly in the alpha and beta frequency ranges. This suggests that magnetic fields can directly influence brain activity in measurable ways.
