Abstract

Overview

The research focuses on the health risks associated with long-term exposure to specific microwave frequencies and their implications on cognitive functions and structures at a cellular level.

Findings

  • Exposure to 2.856 and 9.375 GHz microwaves impacts spatial learning, memory abilities, and synaptic structures.
  • Specific changes in protein expression, such as a decrease in SNARE-associated protein Snapin and an increase in charged multivesicular body protein 3, were identified, suggesting inhibition of synaptic vesicle recycling.
  • Differential protein expression was observed in hippocampal and serum exosomes, including changes relevant to nonthermal effects of microwave exposure.
  • The study identifies potential biomarkers for assessing cognitive and structural changes from microwave exposure.

Conclusion

This study significantly underscores the need for considering long-term nonthermal effects of microwave exposure on cognitive functions and cellular structures, highlighting potential health risks and the importance of ongoing research in EMF safety.
