In the year 1983 brain-electric research (both EEG and dc potentials) on hypnotised and meditating persons led to a very interesting phenomena of modern electro-diagnostics, the discovery of the psychogenic brain-field and the measurement of the ultra slow potential (ULP).

For many years research was done using EEG and biofeedback techniques, to find out how hypnosis, autogenic training, meditation and yoga influence the autonomic nervous system. The focus of the research was the increase of self-healing powers through these techniques.

With the development of a new electrophysical measurement instrument the so called "background" brain activities were made visible and measurable. The modern PcE-Trainer is a simplified embodiment of such an instrument.

Our emotions, well-being, performance capability, health and our whole personality are dependent on the structure of our psychogenic field. How much a person is capable of influencing the psychogenic field with learning and visualization determines the quality of life. A balanced brain-field is equivalent to a highly balanced mind and body.
