Researchers exposed rats to weak static magnetic fields (1 mT) for 50 days and examined brain enzyme activity. They found that magnetic field exposure significantly increased the activity of key brain enzymes involved in nerve communication and energy metabolism, while also causing oxidative stress damage. These enzymes play important roles in neurological diseases, suggesting that even weak magnetic fields can alter brain chemistry.

Researchers exposed human brain cells and mouse neurons to 50-Hz magnetic fields (the type from power lines) at 1 milliTesla and found significant changes in gene regulation. The magnetic fields altered microRNAs (small molecules that control gene expression) and increased production of alpha-synuclein, a protein linked to Parkinson's disease. This suggests that power-frequency magnetic fields may disrupt normal brain cell function through epigenetic changes that could predispose neurons to degeneration.

Russian researchers exposed Alzheimer's mice to extremely weak magnetic fields for 4 hours daily over 10 days. The treatment reduced toxic brain plaques and improved memory in some mice, suggesting specific magnetic frequencies might help clear harmful proteins in early neurodegenerative diseases.
Akbarnejad Z et al. · 2018
Researchers injected rats with Alzheimer's-causing proteins and then exposed them to magnetic fields (50 Hz at 10 milliTesla) for 14 days. The magnetic field exposure significantly improved memory and learning abilities in the Alzheimer's rats, as measured by maze tests. This suggests that certain electromagnetic fields might help protect brain function in neurodegenerative diseases.

Researchers tested whether transcranial magnetic stimulation (TMS) using 60 Hz magnetic fields at 0.7 mT could help treat an animal model of multiple sclerosis. They found that TMS reduced brain inflammation and oxidative stress (cellular damage from unstable molecules) more effectively than standard pharmaceutical treatments. This suggests magnetic field therapy might have protective effects on the nervous system.

Scientists tested whether 50 Hz magnetic fields affect how cancer drugs work on different cell types. The magnetic field protected nerve cells from chemotherapy toxicity by boosting antioxidants, but didn't protect breast cancer cells. This shows EMF can alter medical treatment effectiveness differently across cell types.
Dinčić M et al. · 2018
Researchers exposed rats to static magnetic fields for 50 days and found significant changes in brain enzyme activity, including increased levels of enzymes that control nerve signaling and cellular energy. The magnetic field exposure also increased oxidative stress markers and decreased protective antioxidant activity in brain tissue. These findings suggest that chronic magnetic field exposure can alter fundamental brain chemistry in ways that might affect neurological health.
Consales C et al. · 2018
Researchers exposed brain cells to 50 Hz magnetic fields from power lines and found the fields altered protective gene activity and increased production of a protein linked to Parkinson's disease, suggesting power line frequencies may interfere with the brain's natural cellular defenses.
Budziosz J et al. · 2018
Researchers exposed rats to power-line frequency electromagnetic fields (50 Hz) for 28 days to study effects on brain oxidative stress, which occurs when harmful molecules damage cells. While overall oxidative stress markers remained unchanged, the study found decreased activity of protective antioxidant enzymes in most brain regions. This suggests that even when obvious damage isn't apparent, the brain's defense systems may be working harder under EMF exposure.
Abstract Wireless internet (Wi-Fi) electromagnetic waves (2.45 GHz) have widespread usage almost everywhere et al. · 2017
This 2017 study investigated the effects of radiofrequency radiation emitted from Wi-Fi routers and mobile phone simulators operating at 2.45 GHz on the antibiotic susceptibility of two pathogenic bacteria: Listeria monocytogenes and Escherichia coli. The study examined how wireless electromagnetic exposure might alter bacterial responses to antibacterial agents.

This study examined the effects of 2.4 GHz Wi-Fi electromagnetic exposure on cognitive function in male rats, specifically testing their ability to recognize objects through vision, touch, and combined sensory modalities. Rats exposed to Wi-Fi radiation for 30 days (12 hours daily) showed impaired discrimination between novel and familiar objects across all recognition tasks tested, and demonstrated increased M1 receptor expression in the hippocampus.
AbstractThe present work investigated the effects of prenatal exposure to radiofrequency waves of conventional WiFi devices on postnatal development and behavior of rat offspring et al. · 2017
Researchers exposed pregnant rats to WiFi radiation (2.45 GHz) for 2 hours daily throughout pregnancy and then tracked their offspring's development. The study found that prenatal WiFi exposure delayed normal brain development during the first 17 days after birth and caused oxidative stress in young rat brains. This suggests that WiFi exposure during pregnancy may harm developing nervous systems.

Researchers exposed rats to Wi-Fi radiation (2.4 GHz) for 24 hours daily over one full year and found measurable hearing damage. The study showed decreased hearing sensitivity at 6000 Hz frequency, suggesting that chronic Wi-Fi exposure may harm auditory function. This represents one of the longest-duration Wi-Fi exposure studies conducted on hearing health.
A method of simulating thermal mapping of positioning laptop on laps of an adult man was developed et al. · 2017
This study developed a method to simulate thermal mapping of laptop positioning on an adult man's lap, measuring temperature increases in the glans penis, lap skin, lap muscles, and testes up to 37°C. The title does not clearly indicate an EMF (electromagnetic field) study, appearing instead to focus on thermal effects from laptop heat exposure.

This 2017 review examined associations between proximity to cell towers and general symptoms, as well as school radiofrequency radiation (RFR) levels. The study found limited associations between cell tower vicinity and some general symptoms, but found no association with school RFR levels.
Decreases in sleep duration among U.S. adolescents 2009-2015 & association with new media screen time Twenge JM et al. · 2017
Researchers analyzed sleep data from nearly 370,000 U.S. adolescents between 2009 and 2015, finding teens became 16-17% more likely to sleep less than 7 hours per night. The study linked this decline directly to increased screen time from electronic devices, social media, and online activities, while other potential causes like homework or TV watching remained stable.

Researchers exposed mouse brain cells to pulsed electromagnetic fields (PEMF) and found the treatment protected cells from glutamate damage, a process linked to neurological diseases like Alzheimer's and stroke. The protection worked by activating the brain's natural endocannabinoid system, the same pathway that cannabis affects. This suggests PEMF therapy could potentially help treat neurodegenerative conditions.

Researchers exposed pregnant mice to 7.5 kHz magnetic fields at two different strengths throughout pregnancy and nursing, then tested the male offspring for learning, memory, and behavioral changes. The study found no meaningful effects on brain development, with only two minor changes that researchers attributed to chance rather than actual EMF effects.
Kumari K et al. · 2017
Researchers exposed mice to 7.5 kHz magnetic fields from sources like electronic security systems and induction cooktops for 5 weeks. At higher exposure levels (120 μT), mice showed memory problems and brain inflammation markers, while lower levels (12 μT) had no effect. This suggests intermediate frequency magnetic fields may impair learning through inflammatory brain responses.

Researchers exposed mice to 7.5 kHz magnetic fields for 5 weeks and found that higher exposure levels (120 μT) impaired learning and memory abilities. The mice showed slower learning in maze tests and memory problems after 48 hours, along with increased brain inflammation markers. This suggests intermediate frequency magnetic fields from common devices like induction cooktops may affect cognitive function.
