Abstract

Overview

Exposures to radiofrequency electromagnetic fields (RF-EMFs, 100 kHz to 6 GHz) have raised both scientific interest and public health concerns due to varying effects on cognitive behavior. This study seeks to delve deeper into these phenomena, scrutinizing the direct impacts of RF-EMFs on neuronal functionality.

Findings

• A 60-minute exposure to 3.0 GHz RF-EMF at a low dose (specific absorption rate (SAR) < 1 W/kg) was conducted.
• Observations included a decreased amplitude of action potential, depolarization of neuronal resting membrane potential, and an increase in neuronal excitability and synaptic transmission in cultured primary hippocampal neurons.

Conclusion

The study indicates significant alterations in neuronal activity post-RF-EMF exposure, suggesting potential underlying mechanisms affecting cognitive functions. However, conclusive evidence regarding the non-thermal effects of RF-EMF remains elusive. Further extensive studies are advocated to comprehensively understand these interactions and evaluate health implications.
