Abstract

Overview

The study investigates whether exposure to a 2.45 GHz electromagnetic field affects cognitive functions and brain activity in young rats.

Background

  • Electromagnetic fields may primarily affect cognitive functions.
  • The impact on the brain, especially in young age groups, remains unclear.

Materials and Methods

Twenty-one male Wistar Albino rats, 21 days old, divided into experimental (n=12) and control (n=9) groups. The experimental group was exposed to a 2.45 GHz field for one hour daily for over 28 days. Tests included the Morris Water Maze for assessing cognitive functions and Western Blot method for NMDA receptor analysis, along with EEG measurements.

Findings

  • No significant differences in most measured cognitive aspects in the Morris Water Maze.
  • Significantly longer times to find a visible platform in experimental rats.
  • No difference in NMDA receptor expression.
  • Experimental group showed increased EEG spike frequency and decreased time to first spike.

Conclusion

Significant EEG alterations suggest that 2.45 GHz electromagnetic fields could adversely affect motivation and attention in young rats.
