Abstract

1-hour exposure to ultra-short impulse low-frequency (6 Hz) superbroad band electromagnetic radiation altered cortical EEG in rats just after the exposure and increased the paradoxical sleep in rabbits within 16-22 hours following the radiation.

Main findings

After 1-hour exposure to ultra-short impulse low-frequency (6 Hz) superbroad band electromagnetic radiation, cortical EEG in rats was altered immediately after exposure. Paradoxical sleep in rabbits increased within 16–22 hours following radiation.

Outcomes measured

Cortical EEG alterations in rats (post-exposure)
Paradoxical sleep increase in rabbits (16–22 hours post-exposure)

Limitations

No sample size reported in abstract
Exposure metrics beyond frequency (e.g., field strength, SAR) not reported
Timing and methods for EEG/sleep assessment not described
Species-specific outcomes reported (rats vs rabbits)
