Dr. Soo-Eun Chang joins Peter Reitzes to discuss what causes stuttering from a brain imaging and brain research perspective. This is the fifth episode in a series on the cause of stuttering.
Dr. Chang discusses what brain research tells us or suggests regarding the structure and function of the brains of people who stutter, deficits in white matter tracts, how stuttering may relate to lysosomal dysfunction, persistency and recovery, how the right and left hemispheres interact and much more.
Soo-Eun Chang, Ph.D., CCC-SLP, is the Principal Investigator and Director of the Speech NeurophysiologyLab at the University of Michigan and is an Assistant Professor in the Department of Psychiatry and theRosa Casco Solano-Lopez Research Professor of Child and Adolescent Psychiatry at the University of Michigan. Soo-Eun is also an Adjunct Professor at the Michigan State University, in the Department of Communicative Sciences and Disorders, and the Department of Psychology.
Dr. Paul F. Sowman joins Peter Reitzes to discuss his recently published study in the journal Frontiers in Human Neuroscience which uses neuroimaging to compare the speech production of preschoolers who do and do not stutter. Dr. Sowman’s major finding is that “[Brain] activation was significantly lateralized to the left hemisphere in both groups and not different between groups.”
PAUL F. SOWMAN is a neuroscientist in the Department of Cognitive Science, ARC Centre of Excellence for Cognition and its Disorders, Macquarie University, Sydney, Australia.
Watch a video here of Dr. Sowman conducting and discussing his research with preschoolers.
Deryk Beal, PhD, R-SLP, CCC-SLP, joins Peter Reitzes to discuss brain imaging research, related research and stuttering. Dr. Beal is asked about structural and functional brain imaging research with people who stutter. Dr. Beal is asked to consider this research in relation to gender, severity, recovery, persistency, covert stuttering (passing as fluent), singing, cerebral dominance, other speech disorders (such as apraxia), treatment, relapse and much more. Deryk also discusses deep brain stimulation and direct current stimulation.
DR. DERYK BEAL is an Assistant Professor in the Department of Speech-Language Pathology and Audiology and the Executive Director of the Institute for Stuttering Treatment and Research (ISTAR) at the University of Alberta in Edmonton, Canada. Dr. Beal’s research program aims to understand the neurobiological origins of speech production, stuttering and associated disorders of speech motor control at multiple levels of organization. Deryk’s ultimate goal is to leverage this knowledge for improv cal treatment via genetic risk assessment for dysfluent speech and the development of novel pharmaceutical and neurorehabilitative interventions.

Luc De Nil, Ph.D., Associate Professor and Chair of the Department of Speech-Language Pathology at the University of Toronto, joins Peter Reitzes to discuss brain imaging research, stuttering and much more. Visit Dr. De Nil’s Speech Fluency Laboratory to learn more about his research and publications.
During this episode Dr. De Nil is asked about his behavioural and neuroimaging research pertaining to stuttering and fluency, the possibility that speech therapy is “rewiring” the brain, if stuttering events can occur as a result of learned behavior without a corresponding neurological event, recovery and stuttering, if stuttering is the result of a faulty speech monitoring system, stuttering when you are alone, the future of neuroimaging research and much more.
Thanks to Dr. Tom Weidig at the Stuttering Brain Blog for providing some excellent questions to ask Dr. De Nil.
