Brain waves altered by exposure to RF EMF

  • International Journal of Neuroscience: A 900 MHz cell phone, emitting 3–4 watts adjacent to the ear and brain, induces abnormally slow electroencephalogram waves in the delta band of awake people. This pattern is pathological in awake subjects – (i.e., note similarities to the electroencephalogram of sleeping demential patients). After turning off the phone, the pattern progressively decreased in amplitude, disappearing in ten minutes.
  • NeuroReport: Exposure during waking hours to radiation from a cell phone (900 MHz; 30 minutes; at 1 W/kg) outlasts the waking period. Eelectroencephalogram readings during non-rapid eye movement sleep increased significantly, in the 9.75-11.25 Hz and 12.5-13.25 Hz bands.
  • Journal of Advanced Research: Adverse effect of non-thermal RF EMF exposure (900 MHz, at 0.025 mW/cm2, 1 hour/day, for 1 month) was observed in the physiology of rat brains. REM sleep was significantly delayed, based on electroencephalogram measurements.
  • Journal of Neurophysiology: The alpha band electroencephalogram was significantly affected in volunteers exposed to (non-thermal) radiation from a cell phone, GSM 900 MHz, for 26 minutes. Test design was a double-blind, counterbalanced, crossover study.
  • Bioelectromagnetics: The alpha band of an electroencephalogram shows significantly increased brain activity, when cell phones are activated on the heads of volunteers in a double blind counterbalanced crossover designed test. The alpha brain-wave pattern typically correlates with a “wandering mind“, or “internal thoughts” and “sleep”. Increased alpha readings also correlated with the side of the head exposed to the activated cell phone.
  • Neuroscience Letters: Sleep onset, as measured by electroencephalogram sleepiness rankings, is significantly delayed after exposure to 900 MHz cell phone signals in the talk mode. Cell phone signals in the listen and stand-by modes produced significantly less sleep onset delays.
  • Frontiers in Neuroscience: The elevated brain activity recorded by electroencephalograms during and after cell phone usage can be reduced by chips that are advertised to provide protective effects when they’re attached to mobile phone surfaces.
  • National Research Council (US): Research for proposed “Ground Wave Emergency Network” identified harmful effects from nonthermal exposures including: a) Abnormally slow heart rate (bradycardia), b) Altered Ca2+ binding to the surfaces of nerve cells in isolated brain hemispheres and neuroblastoma cells, c) Abnormal neurotransmitter activity in brain tissue exposed to RF EMF down to 0.45 W/kg, and d) Electroencephalograms (EEGs) of cats exposed to amplitude-modulated frequencies under 25 Hz.
  • Journal of Sleep Research: Electroencephalograms during sleep revealed dose-dependent effects during non-REM sleep, along with decelerated reaction speed, after exposure to cell phone-like signals. Specific absorption rates were: 0.0 W/kg; 0.2 W/kg; or 5 W/kg; in a double-blind, crossover designed test.
  • Journal of Sleep Research: Electroencephalogram study of randomized, double‐blind, crossover design shows brain physiology is affected by both RF EMF (900 MHz; 2 W/kg; 30 minutes) and pulsed magnetic fields. Both non‐rapid eye movement and rapid eye movement sleep are affected.
  • Journal of Sleep Research: Brain physiology altered significantly by pulse‐modulated RF EMF (900 MHz; 2 W/kg; pulse modulated at 14 Hz or 217 Hz; 30 minute exposure; before an 8 hour sleep period). Modulation frequency within a physiological range may be sufficient to induce these effects. Electroencephalogram study design was partially balanced, randomized double‐blind crossover.
  • International Journal of Radiation Biology: The RF EMF emitted by mobile phones affects brain oscillatory responses during cognitive processing in children, as measured by electroencephalogram.
  • Environmental Research: Wi-Fi radiation causes oxidative stress, sperm/testicular damage, neuropsychiatric effects including electroencephalogram changes, apoptosis, cellular DNA damage, endocrine changes, and calcium overload.
  • Brain Stimulation: Sleep characteristics recorded by electroencephalogram show an interaction between RF EMF at 900 MHz and the renormalization of cortical excitability during sleep. There’s an apparent negative impact on normal improvements in sleep-dependent performance.
  • Physiological Chemistry and Physics: Ten human volunteers had temporary changes in their behavior and brain waves, based on electroencephalogram after exposure to power densities well below 10 µW/m2, after exposure (0.1 to 960 MHz, and 8.5 to 9.6 GHz pulse-modulated waves; 10-12 W/cm2 and 10-15 W/cm2; 50 minute duration). Constructive and destructive interference patterns from standing waves within the skull may interact with bioelectric generators in the brain.
  • Clinical Neurophysiology: Exposure to an active mobile phone (900 MHz; Three 20 minute exposures) affects neural functions in humans, altering both resting electroencephalogram patterns and the evoked neural response to auditory stimuli, with a number of these changes occurring as a function of exposure duration.
  • Australasian Physical & Engineering Sciences in Medicine: Mobile phone in talk-mode caused significant difference in the full-power mode trial in the electroencephalogram alpha and beta bands. Statistical analysis of electroencephalogram rhythms revealed significant differences in 7 of the 32 distinct frequencies overall.
  • Journal of Advanced Research: Adverse effect of non-thermal RF EMF exposure (900 MHz, at 0.025 mW/cm2, 1 hour/day, for 1 month) was observed in the physiology of rat brains. REM sleep was significantly delayed, based on electroencephalogram measurements.
