Abstract

Overview

The study investigates the impact of 2.45 GHz microwave radiation on fear memory extinction in male Wistar rats, focusing on understanding how environmental factors like electromagnetic fields can affect psychological processes.

Introduction

Fear memories can be significantly influenced by both psychological and environmental elements. This investigation aims to discern the effects of microwave radiation exposure on the ability of rats to extinguish fear memories, evaluating the potential health risks associated with electromagnetic field exposure.

Methods

• The experimental setup involved young male Wistar rats exposed to 2.45 GHz radio frequency electromagnetic field radiation over both short (7 days) and long-term (30 days) durations, for 1 hour each day.
• Control groups were maintained under identical conditions without exposure to radiation.

Findings

Initial observations revealed a significant decrease in fear responses and body weight after short-term exposure. However, longer exposure did not alter body weight significantly, though it led to a notable reduction in freezing behavior, suggesting alterations in fear memory processes.

Conclusion

Analysis of corticosterone levels suggested that prolonged exposure to radiation might increase stress levels, which correlates with significant physiological changes such as weight loss in subjects. It is crucial to consider these findings as indicative of the potential health risks associated with prolonged exposure to electromagnetic fields.
