Novel recessed curvature electrode to increase selectivity in deep brain stimulation
MetadataShow full item record
Deep brain stimulation (DBS) is a clinical technique utilized in the treatment of neurological conditions such as Parkinson’s disease, and essential tremors. Surgically implanted, DBS electrodes are cylindrical and typically consist of contact points that deliver electrical pulses to the brain. Directional selectivity in deep brain stimulation refers to the radial area of the volume of tissue activated by contact points. Increasing directional selectivity reduces the chances for possible side effects from unnecessary tissue activation. Efficiency is measured by the volume of tissue generated per volt from a contact source. The purpose of this study is to develop a novel electrode to provide for greater selectivity while also maximizing efficiency for the VTA.
