the effects of radiofrequency electromagnetic radiation on neurotransmitters in the brain

The authors of a recent review of research on the effects of radiofrequency electromagnetic radiation (EMR) exposure on the brain and nervous system say “With the rapid development of electronic information in the past 30 years, technical achievements based on electromagnetism have been widely used in various fields pertaining to human production and life. Consequently, EMR has become a substantial new pollution source in modern civilization. The biological effects of EMR have attracted considerable attention worldwide. The possible interaction of EMR with human organs, especially the brain, is currently where the most attention is focused. Many studies have shown that the nervous system is an important target organ system sensitive to EMR. In recent years, an increasing number of studies have focused on the neurobiological effects of EMR, including the metabolism and transport of neurotransmitters. As messengers of synaptic transmission, neurotransmitters play critical roles in cognitive and emotional behaviour. Here, the effects of EMR on the metabolism and receptors of neurotransmitters in the brain are summarized.” **

Cuicui Hu and team reviewed research on the effects of EMR exposure on the brain and nervous system and found that it can cause structural and functional changes in the brain and, hence, the nervous system.

EMR affects neurotransmitters—chemical messengers that convey information through the nervous system and are enormously important parts of the neural circuitry. They are involved in brain development and allow neurons to communicate with each other. Changes in neurotransmitter levels can lead to problems such as depression, schizophrenia and neurodegenerative diseases such as Alzheimer’s and Parkinson’s.

The authors’ review found that EMR affected key neurotransmitters. These include:

  • Dopamine—the neurotransmitter for reward, learning, emotion, motor control and psychiatric and neurological disorders
  • Norepinephrine and epinephrine—involved in stress, attention, sleep, inflammation and the autonomic nervous system responses
  • Serotonin—involved in regulating mood, feeding, cognition, memory, sleep, pain and temperature
  • Glutamate—involved in learning and memory
  • GABA—involved in regulating emotion, sleep, memory, anti-hypertension, analgesia, anti-fatigue
  • Glycine—an antioxidant, a building-block of protein and involved in countering inflammation
  • Acetylcholine—involved in cognition
  • Peptide neurotransmitters—involved in learning and memory
  • Nitric oxide—high levels which can cause neuronal damage.

How EMR causes the effects on neurotransmitters is not certain, however, the authors suggested a few possibilities. Effects could be due to changes in the electrical activity of the brain. They could result from cell membrane damage (such as increased permeability) or from changes in the activity of voltage-gated calcium channels and increased levels of oxidative stress.

Whatever the mechanism, the findings of this review show that exposure is causing changes to the brain that could have an adverse impact on different aspects of our brain and nervous system’s functioning and further research is continuing.

what you can do

  • Reduce mobile phone exposure to your brain by purchasing shielded phone cases and air tube headsets;  
  • Detox your body with activated zeolite; and
  • reduce the exposure in your home with a variety of interventions provided by organisations such as EMR Australia www.emraustralia.com.au
