| Research Abstract |
We have established a novel functional analyzing method by integrating anatomical and electrophysiological information from diffusion tensor imaging, fiber tractography, and deep brain stimulation in patients with advanced Parkinson’s disease. We clearly demonstrated the fiber tracts for pyramidal, extrapyramidal, spinothalamic, and thalamocortical netoworks in patients with deep brain stimulation. By mapping the electrical stimulation effects on the fiber tractgraphy and diffusion tensor imaging data, we generated functional neuroanatomical atlases were in each case. Also non-motor effects of deep brain stimulation were analyzed on the map of tractography, neuronal networks involved in sleep and psychiatric symptoms in advanced Parkinson’s disease.
