In this book, , the authors present their embodiment for a closed loop, feedback controlled, non-invasive application of electrical stimulation of the brain to enhance individual/group performance or to treat neurological disorders. Using a combination of modeling and experimental work, the authors have developed a unique approach to the field in combination with new technology from the perspectives of electro-magnetic and electrical engineering, computation of image processing, machine learning and neural networking, and in conjunction with the medicine of neurology and understanding of neuron behavior. They claim that non-invasive brain stimulation (NIBS) will provide new treatment methods with much greater simplicity, lower cost, improved safety, and in some cases, possibly greater effectiveness than well-established pharmacological methods or more recent invasive electrical deep brain stimulation (DBS) techniques. The authors explain their techniques and the results of their experimental studies and assert that the application of tailored and individualized control of their approach can be combined with other therapy methods to treat neurological disorders while minimizing or even eliminating the use of pharmaceuticals.
