Brain Network Changes After Vibro-tactile Stimulation in Laryngeal Dystonia

To identify the brain networks involved in laryngeal dystonia and any associated changes to this network due to vibro-tactile stimulation (VTS), participants will receive VTS in a controlled laboratory setting for about 20 minutes. They will receive two MRI brain scans, one prior and one after the application of VTS. The scans will take place at the University of Minnesota Center for Magnetic Resonance Research. The total time of the testing procedure that includes receiving VTS and both MRI scans will be approximately 4 hours. This study requires participants to travel Minneapolis.
