Researchers exposed participants to Earth-strength magnetic fields while monitoring their brain activity with EEG. They discovered that specific magnetic field rotations caused measurable changes in brain waves (alpha oscillations), but only when the field was oriented as it naturally occurs in the Northern Hemisphere. This suggests humans possess an unconscious magnetic sensing ability similar to migratory animals.

Researchers exposed bearded dragon lizards to extremely low-frequency electromagnetic fields (ELF-EMF) and found that exposed lizards became more sensitive to natural magnetic field changes, including lunar phases. The EMF-exposed lizards showed increased tail-lifting behavior during full moons, while unexposed control lizards showed no such response. This suggests that artificial EMF exposure may enhance animals' natural magnetic field sensitivity.

Researchers exposed brain cells called astrocytes to 918 MHz radiofrequency radiation (similar to cell phone signals) along with proteins that cause Alzheimer's disease damage. Surprisingly, they found that the RF exposure actually reduced harmful oxidative stress and protected the cells from damage caused by the Alzheimer's proteins. The study suggests that certain RF frequencies might have therapeutic potential for treating Alzheimer's disease.

Researchers studied how weak magnetic fields affect stem cells by examining tissue regeneration in planarians (flatworms that can regrow body parts). They found that depending on the magnetic field strength, these fields could either increase or decrease new tissue formation by altering stem cell activity and cellular stress responses. This suggests weak magnetic fields might be developed as therapeutic tools to control cell growth and healing processes.

Researchers exposed rats to 50 Hz magnetic fields (the same frequency as power lines) for 2 hours daily over 15 days and found the fields produced pain relief (analgesia). They discovered this pain-blocking effect works through serotonin receptors in the brain - the same chemical system involved in mood and sleep. The study shows that extremely low frequency magnetic fields can directly alter brain chemistry and pain perception.

Researchers exposed mice to magnetic fields from power lines during sleep to test effects on their internal body clocks. The magnetic fields caused only minor changes in movement, while light exposure significantly disrupted sleep hormones. Power line magnetic fields don't appear to disrupt circadian rhythms.

Researchers exposed rats with chemically-induced dementia to pulsed magnetic fields (10 mT at 20 Hz) and found dramatic improvements in learning and memory abilities. The treated rats showed 66% faster escape times in maze tests and 55% shorter swimming distances compared to untreated dementia rats. The magnetic field exposure also increased expression of genes linked to brain growth and repair, suggesting the fields may help protect against cognitive decline.

Researchers exposed mice to extremely strong electric fields (35,000 volts per meter) for 49 days to compare how static fields versus power frequency fields affect learning and memory. They found that static electric fields had no effect on cognitive ability, while power frequency electric fields actually improved the mice's performance on memory tests after 33 days of exposure.
Alkis ME et al. · 2019
Turkish researchers exposed rats to cell phone radiation at three different frequencies (900, 1800, and 2100 MHz) for 2 hours daily over 6 months to study brain effects. They found increased DNA damage and oxidative stress in brain tissue across all frequency groups compared to unexposed control rats. This suggests that chronic exposure to the radiofrequency radiation emitted by mobile phones may harm brain cells at the genetic level.

Researchers exposed cockroach nymphs to magnetic fields for 5 months and found significant biological changes, including reduced gut mass and altered antioxidant enzyme activity. The magnetic fields (both static and extremely low frequency) acted as biological stressors, disrupting the insects' cellular defense systems that protect against oxidative damage. This demonstrates that long-term magnetic field exposure can cause measurable biological stress responses in living organisms.

Researchers exposed aphids to high-voltage electric fields for 20 minutes and tracked effects across 21 generations. The brief exposure caused lasting cellular damage and reduced antioxidant defenses that persisted for over 20 generations, showing electric fields can create hereditary biological effects.

Researchers exposed baker's yeast (Saccharomyces cerevisiae) to a strong static magnetic field of 250 millitesla for 6 to 9 hours to study biological effects. They found the magnetic field initially reduced yeast growth and survival, then triggered oxidative stress - a harmful cellular condition where damaging molecules overwhelm the cell's natural defenses. The study demonstrated that even simple organisms like yeast respond to magnetic field exposure with measurable biological changes.

Researchers exposed male rats to extremely low-frequency electromagnetic fields (ELF-EMF) for 2 hours daily over 60 days at various intensities. They found that certain exposure levels improved memory retention and passive learning, but also increased anxiety-like behaviors and oxidative stress (cellular damage from unstable molecules). This suggests ELF-EMF exposure creates a complex mix of both beneficial and harmful effects on brain function.
Jeong YJ et al. · 2018
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.
Consales C et al. · 2018
Researchers exposed lab-grown nerve cells with ALS-related genetic mutations to 50 Hz magnetic fields (the same frequency as power lines) for up to 72 hours. They found that while the magnetic field didn't kill cells or increase oxidative stress, it disrupted iron metabolism genes specifically in cells with the SOD1G93A mutation linked to familial ALS. This suggests that power frequency magnetic fields may interfere with cellular iron regulation in genetically susceptible individuals.

Researchers studied nearly 2,800 Japanese high school students to see if heavy mobile phone use was linked to mood problems. Students using phones more than 33 hours per week showed significantly higher levels of depression, tension, and fatigue compared to lighter users. This suggests that excessive phone use may negatively impact teenagers' mental health.
Lozano-Soto E et al. · 2018
Researchers tested whether placing a static magnet on the back of the head could reduce light sensitivity (photophobia) in 20 healthy volunteers. They found that 10 minutes of magnetic field exposure significantly reduced discomfort from bright lights compared to a fake treatment. This suggests the visual cortex in the brain contributes to light sensitivity and that magnetic field therapy might help treat photophobia in migraine patients.
Kirimoto H et al. · 2018
Researchers applied static magnetic fields to the brain's motor cortex for 15 minutes and found it reduced how strongly participants responded to painful electrical stimuli. The magnetic stimulation appeared to change how the brain processes pain signals, with effects lasting at least 10 minutes after the treatment ended. This suggests static magnetic fields might potentially be developed as a non-invasive treatment for chronic pain conditions.
Gallasch E, Rafolt D, Postruznik M, Fresnoza S, Christova M. · 2018
Researchers exposed 14 healthy volunteers to 20 Hz magnetic fields generated by rotating permanent magnets for 15 minutes, then measured brain activity in the motor cortex (the brain region controlling movement). They found that this magnetic field exposure significantly reduced motor cortex excitability, meaning the brain region became less responsive to stimulation. This demonstrates that even brief exposure to rotating magnetic fields can measurably alter brain function.
Esmaeilpour K et al. · 2018
Researchers studied whether low-frequency electrical stimulation (1 Hz) could help reverse memory problems caused by seizures in rats. They found that applying brief electrical stimulation treatments after seizures not only restored learning and memory abilities but also protected brain cells from seizure-related damage. This suggests that controlled electrical stimulation might offer a therapeutic approach for treating cognitive problems in epilepsy patients.
Dileone M, Mordillo-Mateos L, Oliviero A, Foffani G. · 2018
Researchers applied static magnetic fields to the motor cortex of 45 healthy volunteers for 30 minutes and measured brain activity changes using magnetic stimulation tests. They found that longer magnetic field exposure (30 minutes) created lasting changes in brain excitability that persisted for at least 30 minutes after exposure ended, while shorter exposure (10 minutes) produced only temporary effects. This suggests that magnetic field duration matters significantly for how our brains respond to electromagnetic stimulation.

Researchers studied 57 stroke patients who received either standard physical therapy alone or combined with extremely low frequency electromagnetic field (ELF-EMF) therapy. Patients receiving the electromagnetic field treatment showed significantly reduced oxidative stress markers in their blood and better improvements in daily activities, mental function, and depression scores compared to those getting standard therapy alone. This suggests that ELF-EMF therapy may enhance stroke rehabilitation by reducing cellular damage and improving recovery outcomes.
Cichon N et al. · 2018
Researchers studied 48 stroke patients who received either standard physical therapy alone or physical therapy plus extremely low frequency electromagnetic field (ELF-EMF) treatment. They found that patients receiving ELF-EMF therapy showed significantly increased activity in genes that produce antioxidant enzymes - the body's natural defense system against cellular damage. This suggests ELF-EMF therapy may help stroke patients recover by boosting their cells' ability to protect themselves from harmful oxidative stress.
Cichoń N et al. · 2018
Polish researchers studied whether extremely low frequency electromagnetic fields could help stroke patients recover brain function during rehabilitation. They found that patients receiving EMF therapy alongside standard rehabilitation showed significantly higher levels of brain growth factors that promote healing and scored better on cognitive and functional recovery tests. This suggests EMF therapy may enhance the brain's natural ability to rewire itself after stroke damage.
