Controversies on Electromagnetic in Neurobiology of Organisms: Studies - 1

We are posting here and in the next 3 posts recent studies on electromagnetic fields published in the September 2016 issue of the Journal of Chemical Neuroanatomy.  Clicking on titles of the studies will take you to the abstract or, in the first study, to the full text. (Some of these have already been posted in this blog under "EMF studies".)

Highlights
• 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.



Electromagnetic field and brain development
doi:10.1016/j.jchemneu.2015.11.005
• How electromagnetic field affects the brain development?
•Experimental and clinical studies about the electromagnetic field.

Abstract

Rapid advances in technology involve increased exposures to radio-frequency/microwave radiation from mobile phones and other wireless transmitting devices. As cell phones are held close to the head during talking and often stored next to the reproductive organs, studies are mostly focused on the brain. In fact, more research is especially needed to investigate electromagnetic field (EMF)’s effects on the central nervous system (CNS). Several studies clearly demonstrate that EMF emitted by cell phones could affect a range of body systems and functions. Recent work has demonstrated that EMF inhibit the formation and differentiation of neural stem cells during embryonic development and also affect reproductive and neurological health of adults that have undergone prenatal exposure. The aim of this review is to discuss the developing CNS and explain potential impacts of EMF on this system.

Highlights
• Overview to different frequencies of electromagnetic field radiation exposure.
• Possible side effects of microwave radiation on the central nervous system.
• Qualitative and quantitative analysis to reveal the effects of the electromagnetic field exposure.

Abstract

Microwave radiation (MWR) leads to hazardous effects on he central nervous system (CNS) for both human and animals. The widespread use of mobile phones has increased the risks of health problems in the CNS caused by radiofrequency (RF) electromagnetic fields. To determine these effects various methodological approaches related to neuroscience such as stereology, immunohistochemistry, and electron microscopy have been used. These approaches examine the effects on cells exposed to MWR at the light microscopic and ultrastructural levels, and novel information is obtained. The main aim of this paper is to discuss possible side effects of MWR in the light of current literature with different methodological approaches.



Controversies related to electromagnetic field exposure on peripheral nerves
doi:10.1016/j.jchemneu.2015.12.008
• How electromagnetic field affects the peripheral nerve structure?
• Experimental and clinical studies of nervous system on the electromagnetic field.

Abstract

Electromagnetic field (EMF) is a pervasive environmental presence in modern society. In recent years, mobile phone usage has increased rapidly throughout the world. As mobile phones are generally held close to the head while talking, studies have mostly focused on the central and peripheral nervous system. There is a need for further research to ascertain the real effect of EMF exposure on the nervous system. Several studies have clearly demonstrated that EMF emitted by cell phones could affect the systems of the body as well as functions. However, the adverse effects of EMF emitted by mobile phones on the peripheral nerves are still controversial. Therefore, this review summarizes current knowledge on the possible positive or negative effects of electromagnetic field on peripheral nerves.
