=====Directional lead=====
[[Deep brain stimulation]] of different targets has been shown to drastically improve symptoms of a variety of neurological conditions. However, the occurrence of disabling side effects may limit the ability to deliver adequate amounts of current necessary to reach the maximal benefit. Computed models have suggested that reduction in [[electrode]] size and the ability to provide directional [[lead]] stimulation could increase the efficacy of such therapies
