Abstract

Overview

Wireless internet (Wi-Fi) electromagnetic waves, commonly at 2.45 GHz, are extensively utilized in various environments, including domestic settings. Notwithstanding their widespread adoption, concerns regarding their potential adverse effects on the nervous system persist.

Study Objectives & Methodology

This study specifically explores the influence of 2.4 GHz Wi-Fi radiation on multisensory integration in male Wistar rats. Conducted as an experimental analysis, the research involved 80 rats divided into exposure (Wi-Fi) and sham (control) groups. Wi-Fi exposure entailed 2.4 GHz microwaves at specific settings (23.6 dBm power and 3% duty cycle) over a duration of 30 days, at 12 hours daily.

  • Tests Performed: Cross-modal visual-tactile object recognition (CMOR) including variations like standard SOR, tactile SOR, visual SOR, and CMOR tests.
  • Assessments: Discrimination ratio to determine recognition of new versus familiar objects; mRNA expressions of M1 and GAT1 in the hippocampus via quantitative real-time RT-PCR.

Findings

The experimental results indicated a significant impairment in the ability of rats exposed to Wi-Fi to distinguish between novel and familiar objects across all tested modalities. An increase in M1 receptor expression following exposure to Wi-Fi was also noted, implying potential neuromodulatory alterations.

Conclusion

Chronic exposure to Wi-Fi electromagnetic waves substantially impairs both unimodal and cross-modal encoding of information in rats, suggesting potential risks to cognitive functions and nervous system integrity.
