Network Targeted Transcranial Direct Current Stimulation (tDCS) as a Treatment for Laryngeal Dystonia (LD)
Yale University
Summary
This project will apply transcranial direct current stimulation (tDCS) to multiple brain areas to evaluate the effects as a potential treatment for laryngeal dystonia (formerly spasmodic dysphonia).
Description
Baseline neuroimaging data will be acquired from all participants via MRI, EEG. Each participant will be seen for multiple testing sessions over a five day period. LD participants will undergo the neuromodulation (HD-tDCS Stimulation) for twenty minutes while engaged in watching videos/movies or performing a word production task.
