The Speech Neurophysiology lab conducts research on the neural bases of developmental stuttering, a neurodevelopmental disorder characterized by frequent occurrences of sound-syllable repetitions, prolongations, and blocks that interrupt the flow and rhythm of speech production. Stuttering affects approximately 1% of the population, and 5% of preschool age children. The cause of stuttering is unknown, although accumulating evidence points to a neurodevelopmental etiology. Treatment options for stuttering remain limited.

Our studies involve analyses of brain functional and structural measures acquired through multimodal neuroimaging methods such as fMRI, DTI, structural MRI, fNIRS, and EEG.  Using these techniques, we are able to examine subtle differences in brain functional and structural connectivity that differentiate people who stutter compared to people who do not stutter. These findings are expected to help us better understand the mechanisms behind stuttering onset, persistence, and recovery and further lead to investigations to develop novel treatments for stuttering in the future.

Funded by the NIH (National Institute on Deafness and Other Communication Disorders (NIDCD)), our lab also conducts one of the first studies to examine brain developmental trajectories in children who stutter. This research is expected to lead to novel insights into the brain bases of stuttering during childhood. This research is currently being conducted at both the University of Michigan (Ann Arbor) and the Michigan State University (MSU) (East Lansing) campuses.

Madeline Van Eck has joined the lab as the lab manager on the MSU campus. To read more about Madeline, click here. Madeline replaces Chelsea Johnson, who will be transitioning as a PhD student this fall at MSU, in the department of Communicative Sciences and Disorders. She will still work in the lab but now as a doctoral student. Congratulations to both Madeline and Chelsea!
