Effect of radio-frequency electromagnetic radiations (RF-EMR) on passive avoidance behaviour and hippocampal morphology in Wistar rats. med./bio.

Published in: Ups J Med Sci 2010; 115 (2): 91-96

Aim of study (acc. to author)

To study the effect of radiofrequency electromagnetic field exposure from mobile phones on passive avoidance behaviour and hippocampal morphology in male rats (n=12). A group of another 12 rats formed the control group.

Main outcome of study (acc. to author)

Passive avoidance behaviour was significantly affected in mobile phone-exposed rats demonstrated as shorter latency to enter the dark compartment when compared to the control rats. Marked morphological changes (shrunken, darkly stained neurons) were also found in the CA3 region of the hippocampus of the exposed rats.
The authors conclude that mobile phone exposure significantly altered the passive avoidance behaviour and hippocampal morphology in rats.
