Abstract

Overview

This study addresses the impacts of a 2.45 GHz electromagnetic field on young weaned rats, focusing on cognitive functions, brain receptor expression, and EEG modifications.

Materials and Methods

  • Twenty-one male Wistar Albino rats aged 21 days were divided into experimental and control groups.
  • The experimental group was exposed to a 2.45 GHz EM field for one hour daily over 28 days.
  • Cognitive capabilities were tested using a Morris Water Maze, EEG records were taken, and hippocampi were analyzed for NMDA receptor expression.

Findings

  • No significant differences in Morris water maze performance, except for increased time to reach a visible platform in the experimental group.
  • Spike frequency in EEG was higher and the onset of the first spike was faster in the exposed rats, indicating potential disruptions in normal neurological activity.
  • Expression levels of NMDA receptors in experimental and control groups remained unchanged.

Conclusion

The exposure to a 2.45 GHz electromagnetic field may pose risks to EEG, motivation, and attention, particularly in younger animals. This highlights a potential health risk of EMFs in regards to attention and neurological functions in young organisms.
