Deep Brain Stimulation

This lecture covers the concept of deep brain stimulation, a neurosurgical procedure involving the implantation of a medical device called a neurostimulator to send electrical impulses to specific targets in the brain. It explores the applications of deep brain stimulation in treating various neurological conditions such as essential tremor, obsessive-compulsive disorder, Parkinson's disease, and epilepsy. The lecture also delves into the mechanisms of action behind deep brain stimulation, focusing on how it inhibits neurons around the electrode and excites fiber tracts in different brain regions. Additionally, it discusses the different types of neurostimulators used in deep brain stimulation procedures and the potential future advancements in the field, such as miniaturized and high-density brain electrodes.
