Effect of Δ-Rhythm-Modulated Extremely High Frequency Electromagnetic Radiation on Rats med./bio.

Published in: Bull Exp Biol Med 2004; 137 (5): 423-424

Aim of study (acc. to author)

To test in experiments the possibility of electrosleep induced by extremely high frequency electromagnetic irradiation modulated with a frequency equal to cerebral delta-rhythm oscillations.

Background/further details

Deep sleep induced by electric stimulation (electrosleep) is widely used in diagnostics and therapy of various diseases.

Additional info

The carrier frequency was modulated at 3.5 Hz (Δ-rhythm of the brain), at 15 Hz, and at 18.75 Hz (β-rhythm of the brain). It is not really clear from the article, which of the three frequencies was used when.
