A Systematic Review of the Impact of Electromagnetic Waves on Living Beings

Research RF Safe Research Library Jan 1, 2025

This PRISMA-adherent systematic review searched PubMed, Scopus, and the Cochrane Library for studies (2017–2024) on physiological or behavioral responses to EMF exposure, emphasizing studies reporting harmful or concerning effects. Across 24 included studies (human non-randomized, in vitro, and animal), the review…

Effects of Head-Only Exposure to 900 MHz GSM Electromagnetic Fields in Rats: Changes in Neuronal Activity as Revealed by c-Fos Imaging without Concomitant Cognitive Impairments.

Research RF Safe Research Library Jan 1, 2024

This rat study used a head-only 900 MHz GSM exposure system to assess brain activity changes via c-Fos imaging and to test spatial memory performance. Acute exposure (2 h) was associated with dose-dependent, region-specific increases in c-Fos expression, while repeated pre-training exposures were associated with…

Measuring Electromagnetic Field Activity Generated by Neurons In Vivo by Humans With Thoughts of Repetitive Motor Activities and Emotional Thoughts.

Research RF Safe Research Library Jan 1, 2022

This study describes a helmet-based, non-contact method to continuously measure electromagnetic field activity associated with human brain neuronal activity during thought tasks. Volunteers performed motor movement, motor imagery, and emotional imagery while brain EMF was recorded. The authors report discernible…

Acute exposure to high-induction electromagnetic field affects activity of model peripheral sensory neurons.

Research RF Safe Research Library Jan 1, 2018

This in vitro study examined acute low-frequency electromagnetic field (LF-EMF) exposure using high-induction magnetic stimulation in F11 cells, a dorsal root ganglia neuron-derived model of peripheral sensory neurons. Short-term exposure (

A Single Exposure to GSM-1800 MHz Signals in the Course of an Acute Neuroinflammatory Reaction can Alter Neuronal Responses and Microglial Morphology in the Rat Primary Auditory Cortex.

Research RF Safe Research Library Jan 1, 2018

This animal study examined whether acute GSM-1800 MHz exposure affects the auditory cortex during experimentally induced neuroinflammation. In LPS-treated rats, a single 2-hour head-only exposure (average SAR 1.55 W/kg in auditory cortex) was associated with altered microglial morphology and reduced neuronal activity…

Non-conductive and miniature fiber-optic imaging system for real-time detection of neuronal activity in time-varying electromagnetic fields.

Research RF Safe Research Library Jan 1, 2017

This paper describes a non-conductive, miniature fiber-optic imaging system designed to record neuronal activity in real time during repetitive, long-term time-varying EMF exposure. Using the system, the authors report that short exposures (
