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.
