The deep brain stimulation (DBS) is an effective treatment modality of the functional neurosurgery for disorders such as Parkinson's disease, essential tremor and generalized dystonia. Recently, the targets of DBS for treatment of Parkinson's disease are the thalamus, the Globus pallidus and subthalamic nucleus (STN). The STN-DBS induces improvements in axial motor fluctuation and the on-off phenomenon. ⋯ We devised a three-dimensional atlas to see an image at a free angle on a personal computer. It provided us with more useful information about structures than ones by two-dimentional images. Three-dimensional atlas also helped us make a decision for placement of the deep brain electrode and appropriate electrophysiological recording.
