The present invention relates to a non-invasive system with diagnostic and treatment capacities that use a unified code that is intrinsic to physiological brain function. In an embodiment of the present invention, an approach to the treatment of disorders that supplements existing diagnostic and treatment methods with robust quantitative data analysis are presented. This is achieved by a unification of cognitive and neural phenomena known as the Fundamental Code Unit (FCU), representing identifiable patterns of brain activity at the submolecular, molecular, and cellular levels (intra-brain communications), as well as their manifestations in thought and language (inter-brain communications).
