Researchers exposed middle-aged mice to cell phone-level radiofrequency radiation (1950 MHz) for 8 months to see if it worsened age-related brain damage. While the aging mice showed expected increases in brain oxidative stress, DNA damage, and inflammation markers, the RF exposure didn't make any of these problems worse. The study suggests that long-term exposure to this type of radiation may not accelerate brain aging processes.

Researchers exposed rats to 50 Hz magnetic fields for 60 days and found significant changes in brain molecules that control gene expression. Young female rats showed the most dramatic effects, with altered patterns in both brain tissue and blood, suggesting chronic EMF exposure may disrupt normal brain function.

Japanese researchers analyzed mobile phone ownership among 82 young brain tumor patients (ages 6-18) and compared it to the general population. They found no difference in phone ownership rates between brain tumor patients and healthy children of the same age. The study suggests that mobile phone use was not associated with increased brain tumor risk in this young population.

Researchers followed 1,198 mother-child pairs to examine whether mobile phone use during pregnancy affects children's brain development in their first three years. While they found no direct link between prenatal phone use and developmental delays, children whose mothers had both high lead exposure and heavy phone use showed increased risk of developmental problems. This suggests that RF radiation might amplify the harmful effects of other toxins during pregnancy.

Researchers exposed young mice to 10 GHz microwave radiation (similar to frequencies used in radar and some wireless communications) for 2 hours daily over 15 days. The exposed mice showed impaired spatial memory, brain tissue damage, and disrupted brain chemistry both immediately after exposure and weeks later. This suggests that developing brains may be particularly vulnerable to microwave radiation effects that persist even after exposure ends.

Researchers exposed pregnant rats to 2.45GHz WiFi signals (the same frequency used by most home routers) for 2 hours daily throughout pregnancy, then tested their offspring for developmental and behavioral changes. They found that prenatal WiFi exposure altered physical development and caused anxiety, motor problems, and learning difficulties in the young rats, with effects being more severe when combined with maternal stress. The study also revealed oxidative stress (cellular damage) in the brains of exposed offspring.
Ibitayo AO et al. · 2017
Researchers exposed young male rats to Wi-Fi radiation at 2.5 GHz for 30, 45, and 60 days to study brain effects. They found DNA damage and vascular congestion (blood vessel swelling) in the brain tissue that worsened with longer exposure periods. This suggests that everyday Wi-Fi exposure may cause cumulative damage to brain cells and blood vessels over time.
Birks L et al. · 2017
Researchers analyzed data from 83,884 mother-child pairs across five countries to examine whether cell phone use during pregnancy affects children's behavior. They found that mothers who used cell phones more frequently during pregnancy were more likely to have children with hyperactivity and attention problems by ages 5-7. The study suggests prenatal EMF exposure may influence brain development, though the researchers acknowledge other factors could explain these connections.

Australian researchers followed 412 primary school children for up to 3 years to see if using mobile phones and cordless phones affected their thinking abilities. They found mixed results - increased mobile phone use was linked to some changes in cognitive performance, including faster response times on some tasks but slower response times on others. The researchers concluded there was limited evidence that phone use significantly impacts children's cognitive function.

Researchers exposed young rats to 900 MHz radiofrequency radiation (similar to cell phone frequencies) for one hour daily during adolescence and examined their brain tissue. They found significant damage to the cerebellum, including fewer Purkinje cells (critical neurons for movement and coordination) and abnormal cell arrangement in exposed animals compared to unexposed controls. This suggests that even brief daily EMF exposure during brain development may cause lasting neurological damage.

Researchers exposed young mice to 10 GHz microwave radiation (similar to some WiFi and cellular frequencies) for 2 hours daily over 15 days and found significant damage to developing brains. The exposed mice showed impaired spatial memory, disrupted brain chemistry, and visible tissue damage in key brain regions including the hippocampus. These effects persisted weeks after exposure ended, suggesting the developing brain is particularly vulnerable to microwave radiation.
Xu F et al. · 2017
Scientists exposed young mice to cell phone radiation (1800 MHz) for 8 hours daily over three days. The radiation disrupted brain stem cell development in 7-day-old mice but not 21-day-old mice, suggesting developing brains are more vulnerable to electromagnetic fields than mature brains.

Researchers exposed pregnant rats to WiFi signals (2.45 GHz) for 2 hours daily throughout pregnancy and studied the offspring's development and behavior. They found that prenatal WiFi exposure caused developmental delays, anxiety-like behavior, motor problems, and brain oxidative stress in the offspring, with male rats showing more severe effects. The study suggests that WiFi exposure during pregnancy may harm brain development and behavior in offspring.

Researchers exposed 65 young adults to magnetic fields similar to power lines for three minutes. Participants showed slower reaction times after exposure compared to fake treatment, while sleepiness levels remained unchanged. This demonstrates that brief magnetic field exposure can impair cognitive performance and brain function.
Miao X et al. · 2017
Researchers exposed young male mice to electromagnetic pulses (EMPs) for four weeks and found significant damage to sperm production and testicular health. The mice that received a protective antioxidant supplement (selenium-rich Cordyceps fungi) showed much less reproductive damage. This suggests that electromagnetic radiation can harm male fertility, but certain protective compounds might help reduce this damage.

Japanese researchers analyzed brain cancer rates among young adults from 1993 to 2010 to see if rising mobile phone use could explain increasing cancer incidence. While they found brain cancer rates did increase during this period (ranging from 2.7% to 12.3% annually depending on age and gender), the patterns didn't match what would be expected from mobile phone exposure. The study concluded that heavy mobile phone use cannot explain the overall increase in brain cancers among young Japanese adults.
Redmayne M et al. · 2016
Australian researchers followed primary school children to see if using mobile and cordless phones affected their thinking skills and memory. They found very little evidence that phone use impacted cognitive function, with only 5 out of 78 measured outcomes showing any differences between phone users and non-users. The study suggests that at typical usage levels for young children, these devices don't appear to significantly harm developing cognitive abilities.
Calvente I et al. · 2016
Spanish researchers measured radiofrequency radiation around the homes of 123 ten-year-old boys and tested their cognitive abilities and behavior. While most measures showed no effects, boys living in areas with higher RF exposure (though still below safety guidelines) had lower verbal skills and higher rates of anxiety-related behaviors compared to those in lower exposure areas. The researchers cautioned that study limitations prevent drawing definitive conclusions.
Redmayne M et al. · 2016
Australian researchers studied 619 primary school children (ages 8-11) to see if using mobile phones and cordless phones affected their thinking abilities and reaction times. The children used phones very little (about 2-3 calls per week), and the study found almost no differences in cognitive performance between phone users and non-users. Only 5 out of 78 different measurements showed any statistical differences, suggesting phone use at these low levels doesn't meaningfully impact children's brain function.
Calvente I et al. · 2016
Spanish researchers measured radiofrequency electromagnetic field exposure around the homes of 123 ten-year-old boys and tested their cognitive abilities and behavior. Boys living in areas with higher RF exposure (though still below safety guidelines) showed some concerning patterns including lower verbal skills and higher rates of anxiety-related problems. While the study found mostly no effects, the few significant associations raise questions about environmental RF exposure during critical brain development years.

Researchers exposed developing chick embryos to 900 MHz mobile phone radiation for 10 hours daily during incubation, then tested their social behaviors and brain development after hatching. The radiation-exposed chicks showed significantly impaired social behaviors - they were slower to join groups, less likely to stay with other chicks, and made weaker vocalizations. Brain scans revealed that their cerebellums (the brain region controlling movement and coordination) were smaller than normal.
Oster S et al. · 2016
German researchers developed a sophisticated laboratory system to expose developing rat brain neurons to 900 MHz radiofrequency radiation (similar to cell phone frequencies) for weeks at a time. The study focused on creating reliable equipment to test whether wireless radiation affects developing brain tissue, using exposure levels of 362 milliwatts per kilogram. While the paper describes the experimental setup in detail, it doesn't report specific biological effects, serving instead as a foundation for future research on how RF radiation might impact the developing nervous system.
Stasinopoulou M et al. · 2016
Researchers exposed pregnant rats to DECT phone base station radiation (the same frequency as cordless phones) for 12 hours daily during pregnancy and early life. They found increased heart rates in developing embryos, altered birth measurements in newborns, and significant brain cell loss in the hippocampus region of 22-day-old pups. These brain changes occurred whether the animals were exposed only before birth or both before and after birth.

Researchers exposed both young and elderly rats to cell phone radiation (900 MHz) for 45 minutes daily over one month to see if aging brains were more vulnerable to EMF effects. The study found that while elderly rats showed expected age-related brain problems, the radiation exposure didn't make these problems worse. Interestingly, both young and old rats exposed to radiation showed reduced anxiety-like behaviors.
