Organization and Development of Motor Cortical Circuits for Speech Production in Stuttering
University of Michigan
Summary
The overall objective of this study is to examine inter effector areas (IEAs) activity and functional connectivity during continuous speech production in stuttering adults.
Eligibility
- Age range
- 18–65 years
- Sex
- All
- Healthy volunteers
- No
Inclusion Criteria: * Are between the ages of 18-65 years * Have otherwise normal speech, language, hearing and cognition * Speak English as their primary language * Currently stutter Exclusion Criteria: * Have serious medical or neurological conditions (e.g., stroke, traumatic brain injury, Parkinson's disease, etc.) * Have had a closed head injury (e.g., concussion) * Have a reading disorder (e.g., dyslexia) * Have hearing loss * Have metal or electronic implants (e.g., cochlear implants, pacemakers, etc.) * Are currently pregnant
Interventions
- BehavioralSpeech Production During functional magnetic resonance imaging (MRI)
Participants will complete a speech production task with 2 conditions (stuttered, non-stuttered) while undergoing functional MRI to assess brain activity. Brain activity will be compared within subjects for the 2 conditions. The intervention is the combination of tasks delivered to all participants. The speaking task is the intervention (modifying agent) and the MRI is a measurement tool, not a therapeutic or modifying agent.
