Modulation of Sensory Acuity With Transcranial Magnetic Stimulation (TMS)

NCT06234059 · Status: WITHDRAWN · Phase: NA · Type: INTERVENTIONAL

Last updated 2025-07-29

No results posted yet for this study

Summary

The purpose of this research study is to understand how the brain processes and controls speech in healthy people. The investigators are doing this research because it will help identify the mechanisms that allow people to perceive their own speech errors and to learn new speech sounds, which may be applied to people who have communication disorders. 15 participants will be enrolled into this part of the study and can expect to be on study for 4 visits of 2-4 hours each.

Interventions

DEVICE

TMS

This paradigm uses theta-burst transcranial magnetic stimulation (tbTMS) to modulate the excitability of sensory cortices to examine the effect on sensory acuity and sensorimotor adaptation. Participants will complete three total sessions targeting primary somatosensory cortex (S1): one using intermittent theta-burst stimulation (iTBS), one using continuous theta-burst stimulation (cTBS), and one with sham stimulation.

BEHAVIORAL

Speaking Tasks

Participants will produce four training words under a vowel centralization feedback paradigm in which auditory feedback is altered. The investigators will measure changes in produced vowels as a result of the altered feedback in concert with the different stimulation regimes described in the TMS intervention.
