This text presents a comprehensive and state-of the-art approach to stereotactic and functional neurosurgery. Overarching sections include achieving stereotactic precision, defining trajectories and targets, the biophysics of stereotactic therapies, diseases and targets, and the future of functional neurosurgery. Each section is designed to be inclusive of all relevant topics, serving as an unbiased resource to new clinicians in this field or established clinicians that are aiming to better understand complementary methods. Importantly, each section and the associated chapters can be used by basic and translational scientists as well as engineers and industry to better understand and deliver innovation to the field. Chapters within each section methodically analyze traditional and recently emerging concepts and techniques; address underlying principles with examples drawn from specific diseases and applications; and cover patient selection, target selection, available stereotactic methods, nuanced surgical methods, and clinical evidence across treatment options. Written by experts in each area, Stereotactic and Functional Neurosurgery is a definitive guide to the latest developments in stereotactic targeting, electrode implantation, surgical treatment of neurological and psychiatric disorders, the renaissance of stereotactic lesions, and the frontier of restorative neurosurgery for a variety of disorders that have no other therapeutic options.

This issue of Neurosurgery Clinics of North America is devoted to "Advances in Neuromodulation." Editors Won Kim, MD, Antonio De Salles, MD, and Nader Pouratian, MD have assembled the top experts to review topics such as: peripheral nerve stimulation; spinal cord stimulation for gait reanimation and vascular pathology; deep brain stimulation for Tourettes, OCD, depression, Parkinson's disease, eating disorders, dystonia, and headache; and techniques for image-guided deep brain stimulation, advanced imaging for targeting, and closed loop neuromodulation.
