The human brain generates different waves of various frequencies
during the different phases of sleep.
In 1924, the German psychiatrist Hans Berger(1873-1941) connected a
couple of electrodes to a patient's scalp and detected a small current.
This led to the development of the EEG (
Modern medicine knows various brainwaves:
Delta-Waves are in the range from 1 to 4 Hz and
appear during deep sleep, which is unvaluable for regeneration of body,
immunesystem and cells and parallel of the inner psychic balance.
Theta-Waves are in the range from 4 to 8 Hz. They
appear in a state of deepest relaxiation or deep meditation. Daydreams - in their dangerous form
knows as short 'mental absence' during Motorway driving - are undesirable
phases of the Theta-Waves. Their use or generation cab kann long improve the memory and the
ability to concentrate and to learn.
Alpha-Waves are in the range from 8 to 13 Hz. They appear during states
of light relaxiation.
Beta-Wellen are in the range of
14 to 40 Hz. They are the brainwaves during normal wake state
and during excited situations. Situations of light stress and anxiety
can lead to Beta-waves too.
Some esoteric breath exercises can change the brainwaves. Already Prof. Stephan Palos
described in his book "Breath and meditation" strong changed activities of the brain.

Muscle-stimulators : Thru stimulus currents the muscles relaxe.
These devices generate very short impulses and are evtl. not quite safe if used for a long time.

Their effect is based on stimulation of nerves. Because of thir hight currents they are
controversial(depending upon construction).
