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).
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.
