Tomas Ortiz Alonso, Professor of the Department of Psychiatry and Medical Psychology at the School of Medicine, Complutense University of Madrid, coordinated a bio-electrical study to test the effectiveness of Pranan technology to neutralise the effects of electromagnetic fields on cerebral bioelectrical activity. The study concludes that the effect of this technology is of such magnitude in terms of neuro-functional coherence and provides significant differences in a large majority of areas of the brain that its effectiveness can be justified as a means of modifying certain cerebral oscillations due to electromagnetic fields.
