ABSTRACT
INTRODUCTION:
With the tremendous increase in number of mobile phone users world wide, the possible risks of this technology have become a serious concern.OBJECTIVE:
We tested the effects of mobile phone exposure on spatial memory performance. MATERIALS ANDMETHODS:
Male Wistar rats (10-12 weeks old) were exposed to 50 missed calls/day for 4 weeks from a GSM (900/1800MHz) mobile phone in vibratory mode (no ring tone). After the experimental period, the animals were tested for spatial memory performance using the Morris water maze test.RESULTS:
Both phone exposed and control animals showed a significant decrease in escape time with training. Phone exposed animals had significantly (~3 times) higher mean latency to reach the target quadrant and spent significantly (~2 times) less time in the target quadrant than age- and sex-matched controls.CONCLUSION:
Mobile phone exposure affected the acquisition of learned responses in Wistar rats. This in turn points to the poor spatial navigation and the object place configurations of the phone-exposed animals.
