Abstract: (12830 Views) |
| Background: This study was planned to examine
the effects of whole-body exposure to GSM-950 MHz
electromagnetic fields (EMFs) on acquisition and
consolidation of spatial memory in rats using a water
maze task. 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.
