Research Overview

  • -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.

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.

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.

ELABORATION OF A VASCULAR CONDITIONED REFLEX IN MAN TO A CHANGE IN THE TENSION OF AN ELECTROMAGNETIC FIELD OF HIGH FREQUENCY

G. F. Plakhanov, V. V. Vedyushkina

Seven healthy volunteers aged 20-23 years underwent more than 100 plethysmographic tests while exposed to a high frequency field from a DTP diathermy apparatus. The stimulus manipulations did not change the apparatus sound, and calculated temperature rises and induced currents from field changes were far below biological and ambient levels, leading the authors to conclude the field intensity change was the conditioned stimulus.

MICROWAVES AFFECT THERMOREGULATORY BEHAVIOR IN RATS

Stern

During each session, alternating 15-minute control and exposure periods presented 2450 MHz continuous wave microwaves at power densities of 5, 10, and 20 mW/cm². The proportion of time the heat lamp stayed on decreased as microwave power density increased, and a linear regression showed an intercept of 0.324, slope of -0.0063 (p<0.001), with power density accounting for 61% of the variation. Randomization tests confirmed significant differences at all power densities versus zero exposure (p<0.003), except at 5 mW/cm² versus all zero exposures (p=0.023) and versus adjacent 10 mW/cm² (p=0.021).

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.
