Of 2,753 studies examining EMF effects on the brain and nervous system, approximately 84 percent found measurable biological effects.
The scientific evidence demonstrates that radiofrequency electromagnetic fields from mobile phones and wireless devices produce measurable effects on nervous system function and cellular processes in the brain.

Responses of the Mouse to Microwave Radiation During Estrous Cycle and Pregnancy
Roberts Rugh, Edward I. Ginns, Henry S. Ho, William M. Leach · 1975
Researchers exposed individual CF1 mice to 2450 MHz microwave radiation in a waveguide with controlled temperature, humidity, and air flow. Female mice in estrus had a lower average lethal absorbed dose (10.65 cal/g) than those in diestrus (11.50 cal/g). Pregnant mice exposed on gestation day 8 showed teratogenic effects including exencephalies, hemorrhages, resorptions, stunting, and fetal death at absorbed doses of 3 to 8 cal/g, and the response was not all-or-none. As absorbed dose increased, the probability of at least one exencephaly per litter increased, but the relationship was not linear and varied widely among litters. A total of 1096 mice were exposed and monitored individually.
MICROWAVE BIOEFFECTS, CURRENT STATUS AND CONCEPTS
Przemyslaw CZERSKI, Stanislaw SZMIGIELSKI · 1975
The review explains that microwave bioeffects data come from animal experiments, model studies, and epidemiological research on occupationally exposed persons. Animal experiments are divided into acute high dose and chronic low dose exposures, with high dose effects explained by non-uniform deep body heating. Chronic exposure effects, especially frequency and modulation dependent effects in the nervous and hematopoietic systems, cannot be explained by thermal considerations alone.

EFFECT OF 19 MHZ RF RADIATION ON NEUROTRANSMITTERS IN MOUSE BRAIN
James H. Merritt, James W. Frazer · 1975
Mice were exposed to 19 MHz radiofrequency radiation and then euthanized by microwave-heating brain inactivation. There were no significant differences in any neurotransmitters or metabolites when microwave controls were compared to either the E-field or H-field groups. Microwave controls had significantly higher brain content of 5-hydroxyindole acetic acid, serotonin, norepinephrine, and dopamine than conventional controls.

A Study of the Biological Effects of Certain ELF Electromagnetic Fields
A. P. Krueger, E. J. Reed · 1975
Researchers exposed young mice to simulated ELF electromagnetic fields at 45 Hz and 75 Hz at 100 V/m and measured growth rate, serotonin metabolism, and susceptibility to influenza virus. No significant difference in growth rate was found between exposed and control mice across experiments lasting 12 to 26 days. Four separate influenza challenge tests at 75 Hz and 100 V/m found no evidence of altered resistance using cumulative mortality rates and LD50 titers.

Investigation of Electrical Impedance Variations of Dog Brain Tissue During Experimental Metabolic Disturbances
J. LENOIR, C. ROULLET, P. JENIN, A. L. THOMASSET, M. PELLET · 1975
Normal tissue showed about 800 ohms at 5 kHz and 400 ohms at 1 MHz with a stable ratio. Controlled hemorrhage caused impedance to surge when arterial pressure fell below 25–30 mmHg, and recovery failed even after blood transfusion restored pressure. Carbon monoxide inhalation repeatedly raised impedance, with each recovery taking longer than the last.

INTRODUCTION: EFFECTS OF ELECTROMAGNETIC RADIATION ON THE NERVOUS SYSTEM
W. R. Adey · 1975
Studies reported behavioral effects including shortening of human reaction times, of human circadian rhythms, and of subjective estimates of the passage of time in the monkey, using electric fields at 5-15 Hz with a peak amplitude of 2-10 V/m in air. There was a remarkable tuning curve for different modulation frequencies, with increased calcium efflux from the cortex at modulation frequencies between 9 and 20 Hz, but very little increase outside this frequency band. Pulsed electric stimulation of cat cortex with gradients in the range 20-60 mV/cm increased the efflux of both calcium and GABA.

Human Magnetic Effects
Gibson, Moroney · 1974
Thirty-four subjects were exposed to weak constant vertical magnetic fields of about 5,000 gammas, a 10% increment over the ambient geomagnetic field, in a repeated-measures design with two sessions. Calculation attempts were significantly lower in the first trial of the field-on session than in the second trial, the field-off session showed no significant change, and the overall ANOVA across trials was significant.

Long-lasting anti-tremor induced by 2-Br-alpha-ergocryptine in monkeys
Miyamoto T, Battista A, Goldstein M, Fuxe M · 1974
Researchers gave CB 154 to five green monkeys with brainstem lesions that caused tremor. A single dose of CB 154 stopped tremor for about one hour. Repeated dosing stopped tremor for at least 48 hours, with reduced tremor lasting another 24-48 hours after treatment ended. Repeated CB 154 also caused moderate involuntary movements that lasted less long than the tremor relief. CB 154 reduced hypokinesia in three of the five monkeys.

FAQs: EMF & Brain & Nervous System
When you review the peer-reviewed literature on electromagnetic field exposure and brain function, the numbers tell a compelling story: 84% of the 2,753 studies examining this relationship have documented measurable effects. This isn't a fringe concern or preliminary finding. This is the dominant scientific picture, and it deserves your attention. The documented effects span multiple systems within your nervous system.
The SYB Research Database includes 1,950 peer-reviewed studies examining the relationship between electromagnetic field exposure and brain & nervous system. These studies have been conducted by researchers worldwide and published in scientific journals. The research spans multiple decades and includes various types of EMF sources including cell phones, WiFi, power lines, and other common sources of electromagnetic radiation.
83% of the 1,950 studies examining brain & nervous system found measurable biological effects from EMF exposure. This means that 1621 studies documented observable changes in biological systems when exposed to electromagnetic fields. The remaining 17% either found no significant effects or had inconclusive results, which is typical in scientific research where study design and exposure parameters vary.
