Image of Dentatorubrothalamic Tract (IMAGE) Duke University Medical Center Caption The X-shaped pathway of nerve fibers represents the dentatorubrothalamic tract, a pathway inside the thalamus that researchers target with deep brain stimulation to halt uncontrolled tremors. Scientists at Duke Medicine have used ultra high-resolution MRI imaging to produce a 3-D model of the brain stem that offers unprecedented detail of neuronal circuitry that could be used to target treatments for conditions such as Alzheimer's and Parkinson's diseases.
