Sanaz Khosravani, recent PhD graduate in the School of Kinesiology and member of the Human Sensorimotor Control Laboratory (HSC), Arash Mahnan, doctoral student, and Jürgen Konczak, PhD, professor in the School and director of HSC, along with colleagues from Otolaryngology and Speech & Hearing Sciences, published a research article about the neural correlate underlying the voice disorder, spasmodic dysphonia. 

Spasmodic dysphonia (SD) is a debilitating voice/speech disorder without an effective cure. To obtain a better understanding of the underlying cortical neural mechanism of the disease, the researchers analyzed electroencephalographic signals of people with SD during voice production. They found that the disease is characterized by an abnormally high synchronous activity within and across cortical neural networks involved in voice production.
