ElMindA, the sponsor of this study, has developed a novel method to automatically reveal functional networks of brain activity based on analysis of EEG Event Related Potential (ERP) data. This technological platform is capable of providing new metrics of brain function which can assist in patient evaluation and management. The analysis is done in two separate processes which are entirely separate and are performed independently of one another. First EEG data are recorded and analyzed from a group, or several groups, of subjects to establish a set of group patterns which characterized the brain network activity of the group. Second, EEG data from a single subject are processed to enable subject evaluation, as compared to the established group patterns. This individual analysis is the basis of the BNA scores computed for an individual subject.
