Speech motor learning and retention in adults using brain stimulation and fMRI

Official title: Sensorimotor Basis of Speech Motor Learning and Retention

Run by Yale University · NCT06492252 · Data updated 2026-11-12

This study tests whether learning new speech movements and retaining them depend on brain areas beyond the mouth and speech muscles, by using brain stimulation and brain imaging to see how the brain changes relate to getting and keeping new speech skills.

Is this trial a fit for you?

Likely a good fit

Fluent English-speaking, right-handed adults with normal hearing and no speech or reading disorders who have no contraindications to MRI or brain stimulation.

Probably not a fit

Individuals with epilepsy history, implants, or other MRI/brain stimulation contraindications, or with speech/reading disorders, may not benefit or participate safely.

What this trial studies

The study uses transcranial magnetic stimulation and functional MRI to identify brain regions involved in learning and retaining new speech movements. Participants will undergo speech adaptation tasks with Harvard Sentences, while resting-state and task-based imaging track neural activity. The protocol includes sessions to test retention 24 hours after learning, with assessments of brain excitability. The aim is to map how sensory and motor brain areas contribute to motor memory for speech.

Why it matters

Potential benefit: If successful, findings could clarify neural targets for enhancing speech motor learning and memory in people who have speech difficulties.

How similar studies have gone: Previous research using TMS and fMRI has shown connections between motor and sensory brain areas in motor learning, supporting this approach.
