Neurobehavioural effects of electromagnetic fields

Abstract

Very few laboratory studies in children have explored the effects of exposure to low level electromagnetic fields (EMFs) on neurobehavioural function. Studies investigating effect on neurotransmitters, cognitive function and brain activity in adults and animals indicate that acute exposure to EMFs does not appear to engender any consistent physiological or behavioural impairment although a few subtle effects may occur. This suggests that exposure of children to low level EMFs may not cause significant detrimental effects on brain function. However the available evidence is not sufficient to draw any definite conclusions, and further laboratory studies are required. In particular, experiments investigating the effects of radiofrequency (RF) fields on the performance of well-characterised cognitive and behavioural tasks by immature and developing animals are recommended, if studies with children cannot be performed for ethical and practical reasons.

The Sensitivity of Children to Electromagnetic Fields

“…29 Neurobehavioral studies in volunteers and in animals, mostly in adults, have not reported robust responses to ELF exposure 31 ; overall, any changes seen have been subtle, transient, and reversible. Workshop participants thought that there is no reason to suppose a greater sensitivity of CNS neural networks and ion channels to induced electric fields in children or in the embryo or fetus.…”

“…Neurobehavioral studies in volunteers and in animals, mostly adults, have not reported robust responses to RF exposure, particularly that associated with mobile phones. 31 Numerous studies have evaluated developmental effects of RF fields on mammals, birds, and other nonmammalian species. 53,54 These studies have shown clearly that RF fields are teratogenic at exposure levels that are high enough to cause significant increases in temperature.…”

Effects of radio- and microwaves emitted by wireless communication devices on the functions of the nervous system selected elements

“…Wpływ PEM na procesy poznawcze Mimo niezwykle obiecujących wyników badań z 2000 r. [12,13] do ok. 2005 r. stwierdzano głównie niewielki przemijający wpływ oddziaływania PEM na procesy pamięciowe i poznawcze [70,71]. W pracach późniejszych, w miarę poprawiania się metodyki badań dotyczących tego problemu, coraz częściej nie stwierdzano żad-nych efektów oddziaływania PEM telefonii komórko-wej na procesy poznawcze.…”

Nitrik Oksit Sentaz (NOS) İnhibitörlerinin Sıçanlarda Çok Düşük Frekanslı Manyetik Alanın İndüklediği Analjezi Üzerine Etkileri

“…Elektromanyetik alanların (EMA) çok sayıda biyolojik fonksiyonları hücresel, davranışsal ve nörobiyolojik dü-zeyde etkilediği bilinmesine rağmen etki mekanizmaları tam olarak aydınlatılmış değildir (1,2). Genel olarak, EMA ile ilgili parametrelerin değişkenliği ve gerçek biyolojik etkileri ilgili bilgilerin sınırlı olması nedeniyle aktiviteleri ile ilgili değerlendirme yapmak oldukça güçtür.…”
