Abstract

Overview

This study explores the effects of radiofrequency electromagnetic radiation (RF-EMR) emitted from mobile phones on general health, with a specific focus on the nervous system.

Findings

  • Subject rats were exposed to 900 MHz RF-EMR from a dipole antenna for three hours daily.
  • The study was divided into short term (1 week) and long term (4 weeks) exposure.
  • Behavioral parameters were assessed via T-maze tasks with types described as normal and delayed. Local field potentials (LFPs) signals were recorded from the medial prefrontal cortex (mPFC).
  • Results indicated significant delays in task completion among exposed rats, which resolved after the cessation of short-term RF-EMR exposure.
  • Notable changes in theta band power (4-12 Hz) were observed, suggesting that RF-EMR exposure can disrupt normal brain functioning, although temporarily.
  • Classification accuracy of LFP patterns in tasks showed significant deterioration post-exposure.

Conclusion

The study concludes that exposure to RF-EMR can cause temporary disruptions in brain functioning, shown by changes in brain signal patterns and task performance in rats. Further research is warranted to understand the long-term implications of such exposure.
