Whole body exposure to 2.4 GHz WIFI signals: effects on cognitive impairment in adult triple transgenic mouse models of Alzheimer's disease (3xTg-AD).

Banaceur S, Banasr S, Sakly M, Abdelmelek H. · 2013

Researchers exposed mice with Alzheimer's-like symptoms to WiFi signals (2.4 GHz) for two hours daily over a month at levels similar to cell phone exposure. Surprisingly, the WiFi exposure actually improved cognitive performance and memory in the Alzheimer's mice compared to unexposed mice. This unexpected finding suggests radiofrequency radiation might have therapeutic potential for certain brain conditions, though the mechanism remains unclear.

Bilgici B, Akar A, Avci B, Tuncel OK. · 2013

Researchers exposed rats to cell phone-level radiofrequency radiation (900 MHz) for one hour daily over three weeks and measured damage markers in brain tissue. The study found significant increases in two key indicators of cellular damage - lipid oxidation and protein damage - in the brain tissue of exposed animals. Interestingly, rats given garlic powder showed protection against this brain damage, suggesting antioxidants may help counteract RF radiation effects.

The Effects of Cell Phone Waves (900 MHz-GSM Band) on Sperm Parameters and Total Antioxidant Capacity in Rats.

Ghanbari M1, Mortazavi SB1, Khavanin A1, Khazaei M2. · 2013

Researchers exposed male rats to cell phone radiation at 900 MHz (the frequency used by GSM networks) for two to three weeks and measured effects on sperm quality. They found that exposure significantly reduced sperm viability, motility (swimming ability), and antioxidant defenses compared to unexposed rats, with longer exposure causing greater damage. This suggests cell phone radiation may impair male fertility by creating oxidative stress in reproductive cells.

Effects of olive leave extract on metabolic disorders and oxidative stress induced by 2.45 GHz WIFI signals.

Salah MB, Abdelmelek H, Abderraba M. · 2013

Researchers exposed rats to WiFi radiation (2.45 GHz) for one hour daily over 21 days and found it created a diabetes-like condition by damaging the body's natural antioxidant defenses in the liver and kidneys. The WiFi exposure reduced key protective enzymes by 33-68% and increased cellular damage markers by up to 51%. When researchers gave the rats olive leaf extract, it prevented most of the metabolic disruption and restored the protective enzymes, suggesting that WiFi radiation causes harm through oxidative stress.

Ersan Odacı et al. · 2013

Researchers exposed pregnant rats to 900 MHz radiofrequency radiation (similar to cell phone frequencies) for one hour daily during late pregnancy, then examined the spinal cord development and motor behavior of their female offspring. The exposed rat pups showed pathological changes in their spinal cord tissue and unexpectedly increased motor activity on behavioral tests. This suggests that prenatal EMF exposure can alter nervous system development in ways that persist after birth.

The Effects of Prenatal Exposure to a 900 Megahertz Electromagnetic Field on Hippocampus Morphology and Learning Behavior in Rat Pups.

İkinci A et al. · 2013

Researchers exposed pregnant rats to 900 MHz electromagnetic fields (the same frequency used by many cell phones) for one hour daily during late pregnancy. The female offspring showed significant learning and memory problems in maze tests, plus visible damage to the hippocampus, the brain region crucial for learning and memory. This suggests that EMF exposure during pregnancy may harm developing brains in ways that persist after birth.

Nasseri S, Monazzam M, Beheshti M, Zare S, Mahvi A · 2013

Researchers measured microwave radiation patterns around cell phone towers (base stations) in an Iranian city to understand how exposure levels change at different heights and distances. They found that radiation levels increased significantly as measurement height increased, particularly in crowded urban areas where rigid surfaces and high mobile phone usage amplify wave density. The study demonstrates that cell tower placement in populated areas creates higher public exposure to microwave radiation.

Pyramidal Cell Loss in the Cornu Ammonis of 32-day-old Female Rats Following Exposure to a 900 Megahertz Electromagnetic Field During Prenatal Days 13–21

Orhan Baş et al. · 2013

Researchers exposed pregnant rats to 900 MHz radiofrequency radiation (similar to cell phone frequencies) during a critical brain development period and found significant loss of brain cells in the hippocampus region of their female offspring. The exposed rat pups had fewer pyramidal cells in the cornu ammonis, a brain area crucial for memory and learning. This suggests that EMF exposure during pregnancy may harm developing brains, potentially affecting cognitive function later in life.

French researchers exposed pregnant rats and their newborns to WiFi signals (2450 MHz) for 2 hours daily during pregnancy and early life, then examined brain tissue for signs of stress and damage. They found no differences in stress markers or heat-shock proteins between exposed and unexposed rats at any of the tested exposure levels. The study suggests that WiFi exposure during critical developmental periods may not cause detectable brain damage in rats.

No increased sensitivity in brain activity of adolescents exposed to mobile phone-like emissions

Loughran SP et al. · 2013

Researchers exposed 22 adolescents (ages 11-13) to cell phone-like radiation at two different power levels for 30 minutes while measuring brain activity and cognitive performance. They found no significant effects on brain waves or thinking abilities compared to fake exposure sessions. This suggests adolescents may not be more sensitive to mobile phone radiation than previously thought.

Effects of combined radiofrequency radiation exposure on levels of reactive oxygen species in neuronal cells.

Kang KA et al. · 2013

Researchers exposed neuronal brain cells to combined cell phone radiation (CDMA and WCDMA signals) for 2 hours to see if it would increase reactive oxygen species (ROS), which are harmful molecules that can damage cells. The study found no increase in ROS levels from the radiation exposure, even when combined with chemicals known to cause oxidative stress. This suggests the specific radiation levels tested did not trigger cellular damage in these lab-grown brain cells.

Researchers exposed rats to cell phone radiation (900 MHz) for 2 hours daily over 10 months and examined their brains for signs of damage. They found significantly increased protein carbonyl levels, which indicates protein damage from oxidative stress. This suggests that long-term cell phone radiation exposure may harm brain proteins, potentially contributing to neurodegenerative processes.
