Is cognitive function affected by mobile phone radiation
exposure?
Adamantia F. Fragopoulou, Lukas H. Margaritis

Abstract
Behavioral tasks, including the Morris water maze (MWM), radial arm maze
and object recognition task, have been extensively used to test cognitive impairment
following exposure of rodents to mobile phone (MP) radiation on various
frequencies and specific absorption rate (SAR) values. Exposed animals in most
of the cases revealed defects in their working memory possibly due to cholinergic
pathway distraction. The only experiment on mice at very low SAR did not show
statistically significant deficits by 8-arm maze, but our own data in mice exposed
to GSM 900 MHz radiation, revealed memory lesions on MWM task; exposed
mice had difficulties in memory consolidation and/or retrieval of the stored
information. Lastly, a number of studies have been applied to volunteers
showing variable results depending on the experimental setup, revealing
memory improvement or deficits following MP exposure.
The recorded data from the literature are generally favouring the conclusion
that EMF is affecting memory function although a more rigorous and reproducible
exposure system has to be adopted in relation to the recently criticized
importance of SAR.
