Spatial memory performance of Wistar rats exposed to mobile phone med./bio.

Published in: Clinics 2009; 64 (3): 231-234

Aim of study (acc. to author)

To test the effects of mobile phone exposure on spatial memory performance in rats.

Background/further details

Male rats were divided into an exposure group (n=6) and a control group (n=6).



Exposure Parameters
Exposure 1: 900–1,800 MHz
Exposure duration: 50 missed calls/day, separated by 15 s intervals, for 4 weeks

Main outcome of study (acc. to author)

Both, the exposure group and the control group showed a significant decrease in escape time with training. Exposed animals displayed three times higher mean latency to reach the target quadrant and spent two times less time in the target quadrant than the control group.
Mobile phone exposure affected the acquisition of learned responses in rats. The exposed animals showed poor spatial navigation.
