3EGA is a company which bases its actions on previously implemented research in medicine, neuroscience, physics, physiological complexity and the need for improvement and rationalization in present healthcare. We developed a specific methodology utilizing engineering knowledge as well as neurophysiology, biophysics and nonlinear analysis of electrophysiological data based on Dynamical Complex Systems theory (Chaos). We like to describe it as: Evidence-based nonlinear methodology for a clinical decision support service.
