Understanding Disorder-specific Neural Pathophysiology in Laryngeal Dystonia and Voice Tremor

Brain images will be conducted with function MRI, magnetoencephalography (MEG), and electroencephalography (EEG) to identify disorder-specific neural markers

Laryngeal sensory block with bupivacaine will be used to modulate sensory feedback from vocal fold mucosa and examine the impact of sensory feedback on abnormal neural activity in LD and VT
