Phone-exposed rats took about three times longer to reach the target quadrant and spent about two times less time in it than controls.

Plain English Summary

Summary written for general audiences

Researchers exposed male Wistar rats to 50 missed calls per day for four weeks from a GSM mobile phone in vibratory mode. After exposure, the rats were tested for spatial memory using the Morris water maze test. Both exposed and control rats decreased their escape time with training. Phone-exposed rats had about three times higher mean latency to reach the target quadrant and spent about two times less time in it than controls.

Why This Matters

The authors stated that they tested the effects of mobile phone exposure on spatial memory performance. They concluded that mobile phone exposure affected the acquisition of learned responses in Wistar rats. This was interpreted as indicating poor spatial navigation and object place configurations in phone-exposed animals.

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.
