Special Issue Medical Journal of Chemical Neuroanatomy: Controversies on Electromagnetic Fields in Neurobiology of Organisms

Share

The Journal of Chemical Neuroanatomy has just published a special issue with fifteen papers describing groundbreaking research by Turkish researchers on the effects of radio-frequency electromagnetic radiation (RF-EMR) on the developing and adult nervous system. These studies, along with several review articles, investigate how RF-EMR may have negative effects on neurodevelopment, may increase exposure of the brain to toxic compounds by altering permeability of the blood-brain barrier, may induce oxidative stress on the central and peripheral nervous system.

“This special issue pulls together the latest experimental studies from some of the world’s top investigators showing that prenatal exposure clearly causes deficits in brain development in animals as well as deficiencies in their reproductive organs.  It was a privilege to work with leading teams in biophysics and embryology throughout Turkey where research on wireless radiation is considerably more advanced than in the U.S.” Devra Davis, co-editor of this special issue of the journal and Visiting Professor of Medicine, The Hebrew University.

Süleyman Kaplan, Devra Davis. Editorial. Pages 41-42

  • This special issue seeks to make a contribution to current literature about EMF by reviewing some of the basic underlying experimental science in the field relating to assessing impacts of electromagnetic fields on the structure and function of the developing nervous system. We present five reviews, followed by five research papers on the effects of the EMF on the nervous system. Read the full editorial here.

Martin L. Pall. Microwave frequency electromagnetic fields (EMFs) produce widespread neuropsychiatric effects including depression. Review Article. Pages 43-51.

  • Microwave EMFs activate voltage-gated Ca2+ channels (VGCCs) concentrated in the brain.
  • Animal studies show such low level MWV EMFs have diverse high impacts in the brain.
  • VGCC activity causes widespread neuropsychiatric effects in humans (genetic studies).
  • 26 studies have EMFs assoc. with neuropsychiatric effects; 5 criteria show causality.
  • MWV EMFs cause at least 13 neuropsychiatric effects including depression in humans.

Suleyman Dasdag, Mehmet Zulkuf Akdag. The link between radiofrequencies emitted from wireless technologies and oxidative stress. Review Article. Pages 85-93.

  • The results of the studies we reviewed here indicated that mobile phones and similar equipment or radars can be thought as a factor, which cause oxidative stress. Even some of them claimed that oxidative stress originated from radiofrequencies can be resulted with DNA damage. For this reason one of the points to think on is relation between mobile phones and oxidative stress. However, more performance is necessary especially on human exposure studies.
