Abstract :
Background: The central nervous system is sensitive to radiation exposure as environmental pollution. This project aimed to evaluate the influence of jammer exposure radiation on spatial learning and memory. Materials and Methods: 50 adult male Sprague-Dawley rats were divided into five groups.
The experimental groups were exposed to jammer radiation for 2h/day once
or 2h/day for two weeks. Sham groups were similar to the experimental
groups which were exposed to switch-off. The distance from the jammer
router to the animals’ cages was 30 cm. In the second phase, using Morris
Water Maze, the effect of jammer exposure radiation on spatial learning and
memory was studied. Results: Data showed that radiation exposure once a
day for 2h caused a significant increase in the learning procedure in the
experimental group1, but we observed an increase in the parameters of
distance and escape latency in finding the platform for two weeks' exposure
in the experimental group 2. Conclusion: Results indicated that probably the
motivation of escape and use of the different cues led to learning in the
animals, while disrupting mobile performance through jammer router from
animal environment caused a better brain performance in the spatial learning
and memory in short term jammer radiation-treated animals group. However,
with the same test conditions, in long term jammer the radiation-treated
animals’ motivation reduced, which affected the responses and performance
and reduced the learning. Moreover, environmental conflicts such as radiofrequency waves lead to behavioral alternations.
