Stuttering and Neuromodulation
The purpose of this study is to collect preliminary data on the efficacy of transcranial direct current stimulation (tDCS) combined with traditional behavioral…
Brain Mechanisms Underlying Neurotypical and Disordered Speech
This study aims to understand how people use different types of feedback to control their speech. When an individual speaks, the brain relies on several system…
Neural Processing of Speech Signals in Children Who Stutter
The purpose of this research study is to understand how speech and language are processed in the brain. This study will provide information that may help with …
Developmental Trajectories to Stuttering Persistence and Recovery
The goal of this longitudinal research is to learn why some children "grow out" of stuttering, while others persist. Children who do and do not stutter aged 3-…
Auditory Prediction and Error Evaluation in the Speech of Individuals Who Stutter
Stuttering negatively impacts communication and reduces the overall quality of life and well-being of individuals who stutter. This study will provide a strong…
Examining Speech Production Errors in Stuttering Through High Definition - Transcranial Direct Current Stimulation
The goal of this study is to find out whether a type of noninvasive brain stimulation can help reduce speech errors, such as repetitions, blocks, and prolongat…
Improving Neural Oscillation and Synchrony Between Motor and Auditory Regions in Stuttering Using Personalized Transcranial Alternating Current Stimulation (tACS)
The purpose of this study is to investigate how mild, noninvasive electrical brain stimulation affects speech relevant brain areas, which may in turn affect sp…
Subcortical Network Connectivity and Temporal Processing in Children With Persistent and Recovered Stuttering
The specific purpose of this clinical trial is to compare performance on rhythm perception and production tasks between children who stutter and children who d…
Organization and Development of Motor Cortical Circuits for Speech Production in Stuttering
The overall objective of this study is to examine inter effector areas (IEAs) activity and functional connectivity during continuous speech production in stutt…
Modulating Bilateral Cortical Activation In Adults Who Stutter: A Pilot Study
The goal of this clinical trial is to learn if repeated transcranial magnetic stimuli (rTMS) can treat stuttering in adults. The main questions it aims to answ…
Effects of Psilocybin on Speech Fluency, Struggle, and Brain Activity in People Who Stutter
This Phase 2a clinical trial is an open-label, single-group, within-subjects pilot study designed to evaluate the safety, feasibility, and preliminary efficacy…
Dopamine and Sensorimotor Function in Stuttering
This study is being done to understand the effect of aripiprazole on adults who stutter. Stuttering is a disorder that affects speech fluency. This study aims …
