Materials and Methods: In experiment 1, the animals were given two blocks of five trials per day for three consecutive days in a water maze task. The interval between blocks was 4h. Before each training session, the animals were exposed to 950 MHz EMFs for 45 min with lower- (0.835 mW/cm2) or higher-power (1.166 mW/cm2) densities. In experiment 2, the animals were given two blocks of 5 trials with a 3 min interval between blocks. Immediately after the last trial, they were exposed to EMFs for 45 min with lower- or higher-power densities. In both experiments, 48 h after the last training day a 60 s probe test was done. Results: Results from experiment1 (pre-training exposure to EMFs) indicated no significant differences in performances of exposed and non-exposed groups either during acquisition (learning) or during probe test (memory retention). Results from experiment 2 (posttraining exposure to EMFs) also indicated no significant differences among groups during acquisition or probe test. Conclusion: In these experiments, no effect of exposure to 950 MHz on acquisition or consolidation of spatial navigation of rats in a water maze was detected. Iran. J. Radiat.
