Two of these studies were focused in learning and sportive performance, and 2 focused on increasing physical and mental health. Conclusion : It was concluded that the investigation of brain stimulation technique can be applied to induce favorable mental states to enlarge treatments of several disorders that affect humans in a safe and noninvasive way.
