Neuromodulation: Comprehensive Textbook of Principles, Technologies, and Therapies, Second Edition, serves as a comprehensive and in-depth reference textbook covering all aspects of the rapidly growing field of neuromodulation. Since the publication of the first edition seven years ago, there has been an explosion of knowledge in neuromodulation, optogenetics, bioelectronics medicine and brain computer interfacing. Users will find unique discussions of the fundamental principles of neuromodulation and therapies, and how they are applied to the brain, spinal cord, peripheral nerves, autonomic nerves and various organs.
The book focuses on comprehensive coverage of spinal cord stimulation, non-interventional and interventional brain stimulation, peripheral nerve stimulation, and the emerging fields of neuromodulation, including optogenetics and bioelectronics medicine.
