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.
Exposure duration: 50 times 45 s/h once per day for 4 weeks
No parameters are specified for this exposure.
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.
