The Effect of low- frequency electromagnetic fields on motor activity and histomorphometry of the motor area of cerebral cortex in adult male rats

The effect of  low- frequency electromagnetic waves on motor activity and brain tissue motor area in rats was investigated.

In this experimental study, 20 rats were randomly divided into four groups. The first group was designated as the control group, and experimental groups received 900, 1800, and 2450 MHz waves, with an intensity of 2, 1, and 20 watts per kilogram, 4 hours per day for one month respectively. Behavioral evaluation of open field test and histomorphometric evaluation of cortical thickness and count of internal pyramidal cells were determined.

The results showed that low- frequency electromagnetic waves significantly reduced the distance traveled and the time spent in the central open field test area of the experimental groups compared to the control group (p ˂ 0.05). The number of neurons in the inner pyramidal layer and the thickness of the cortical thickness of the frontal lobe showed a significant decrease in the experimental groups compared to the control group (p ˂ 0.05).

Low- frequency electromagnetic waves increased anxiety and decreased motor activity in the behavioral tests with a histomorphometric change of frontal cortex in the experimental groups.
