This double-blind, randomized, crossover study examined whether 30 minutes of near-field LTE radiofrequency exposure near the right ear alters resting-state brain activity measured by fMRI. The authors report decreased ALFF in multiple temporal and frontal/paracentral regions after real exposure compared with sham,…

This animal study examined in vivo and in vitro effects of weak, low-frequency magnetic fields described as having resonance parameters for calcium ions. The authors report a considerable decrease in activity of calcium-dependent proteinases (calpains) in fish skeletal muscle and brain following exposure. The…

This article presents a generalization and analysis of the author's long-term materials on brain responses to low-intensity electromagnetic radiation (~500 microW/cm2, continuous or pulsed) after short exposure (~30 minutes). It describes experimental results at the level of single neurons, brain formations, and the…

This animal study exposed male Fischer-344 rats to 900 MHz or 1800 MHz microwave radiation for 30 days (2 h/day) and compared outcomes to sham exposure. The authors report significant cognitive impairment along with increased oxidative stress in brain tissue in exposed rats. They also report increased inflammatory…

This rat study tested whether acute exposure to 0.9 and 1.8 GHz continuous-wave radiofrequency radiation alters blood-brain barrier permeability. Using Evans-blue/albumin as a tracer, the authors report no BBB leakage in exposed female rats but a significant increase in albumin in exposed male rat brains versus sham.…

This animal study assessed DNA damage in rat brain, liver, and kidney cells after repeated whole-body exposure to 915 MHz GSM-modulated RF radiation (SAR 0.6 W/kg) using the comet assay. Tail length was slightly increased in brain cells and differed more notably in liver and kidney samples versus sham controls, while…

This animal study examined whether an extremely low frequency magnetic field (7 mT, 40 Hz) used in magnetotherapy alters oxidative balance in rat brain after 10 days of exposure. The 30 min/day exposure condition was associated with increased lipid peroxidation, while the 60 min/day condition was associated with…

This animal PET study examined whether a weak 60-Hz magnetic field alters brain glucose utilization in rats. The abstract reports increased FDG uptake in hindbrain voxels when a 2.5-G field was oriented orthogonally to the sagittal plane, but not when field direction varied randomly. Distinct activation effects were…

This paper presents a meta-analysis of 11 peer-reviewed epidemiologic studies examining long-term (>=10 years) cell phone use with laterality analyses. It reports that long-term use is associated with an approximately doubled risk of an ipsilateral brain tumor. The abstract states statistical significance for glioma…

This rat study examined hippocampal aquaporin 4 (AQP4) expression after microwave exposure at 10, 30, or 100 mW/cm^2. The authors report increased AQP4 protein and gene expression after exposure, with recovery at lower power density but more persistent elevation at higher power density. They conclude that increased…

This review discusses reports of headaches occurring with hand-held cellular telephone use and argues they are likely real and attributable to telephone emissions. It points to earlier reports of headaches from low-intensity microwave exposure and proposes biological plausibility via effects on the blood-brain…
