Basal ganglia circuits are affected in neurological disorders such as Parkinsons disease, essential tremor, dystonia and Tourette syndrome. Subject-specific models of the structural and functional connectivity of these circuits are critical for elucidating the mechanisms of these disorders, and developing new treatments. We present a unique ultra-high-field (7T) MRI and computational protocol designed to generate a comprehensive in vivo model of the structure and connections of the human basal ganglia. Our findings open new avenues of investigation into the movement and neuropsychiatric disorders, in individual human subjects.
