Effects of 1.5 and 4.3 GHz microwave radiation on cognitive function and hippocampal tissue structure in Wistar rats

Abstract

Overview

Previous studies indicated that microwave radiation might degrade cognitive abilities in animal models. This study extends the understanding by exploring the cumulative effects of different microwave frequencies on cognitive functions and brain structures.

Methodology

We used 140 male Wistar rats, randomly divided into four groups receiving different treatments. These included sham radiation, 1.5 GHz, and 4.3 GHz frequencies, both individually and in combination, from 1 to 28 days with intensity at 10 mW/cm².

Findings

• Cognitive decline was observed in all radiation-exposed groups compared to the control group through Morris water maze results.
• Microscopic examinations highlighted structural damage in hippocampal tissues with disturbances in cellular metabolic activities.
• Mixed frequency exposure (1.5 and 4.3 GHz) resulted in more severe cognitive and tissue impairments.

Conclusion

The study conclusively shows damaging cognitive and anatomical changes in Wistar rats caused by 1.5 GHz and 4.3 GHz microwave radiation, highlighting potential health risks of electromagnetic fields in living organisms.
