Brain imaging of how people with and without cerebellar stroke hear and produce speech
Official title: High-resolution Functional Imaging of Speech-induced Sensory Modulation
Run by University of Pittsburgh · NCT06458153 · Data updated 2026-11-12
We will use EEG and high‑field MRI to see if brain areas that plan movement and process speech work differently in healthy adults and people who've had a cerebellar stroke.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are right‑handed, native English‑speaking adults who are either healthy (ages 18–49) or have a history of cerebellar stroke (age 18+), meet MRI safety requirements, and pass a hearing test.
✕Probably not a fit
People who have MRI contraindications, significant hearing loss, non‑right‑handedness, or active psychotic disorders are unlikely to qualify and therefore are unlikely to benefit from participation.

What this trial studies
This study uses an intensive within-subject design with up to six in-person sessions to map how motor planning regions and auditory systems interact during speech. Participants perform short speech production and perception tasks while researchers record brain activity with EEG and 7 Tesla functional MRI, plus structural MRI. The sample includes neurotypical adults, people with cerebellar stroke, and matched controls, with extensive sampling of each participant to capture individual patterns. All participants complete a hearing screen and behavioral measures alongside the imaging sessions.
Why it matters
Potential benefit: If successful, the findings could improve understanding of how the cerebellum contributes to speech control and guide better rehabilitation approaches after cerebellar stroke.
How similar studies have gone: Previous EEG and fMRI work has identified related speech and auditory‑motor patterns, but combining ultra‑high field 7T imaging with intensive within‑subject sampling in cerebellar stroke patients is relatively novel.
