Abstract

Overview

The study investigates the effects of high-power electromagnetic pulses (EMPs) on healthy mice, focusing on cognitive functions and neuronal dynamics in the hippocampus.

Findings

  • EMP exposure was found to affect spatial learning and memory adversely.
  • Neuronal activities in the hippocampal CA1 area were disturbed during and after EMP exposure, showing inhibited activity during exposure and heightened activity immediately after.
  • Structural damages in neurons of the hippocampus were observed through microscopy after EMP exposure.

Conclusion

This research highlights significant neuronal and cognitive impairments due to EMP exposure in mice, indicating potential health risks of electromagnetic fields on brain functions.
