Understanding how our brains process the sound of our own voice
High-resolution functional imaging of speech-induced sensory modulation
This project aims to understand how our brains adjust to hearing our own speech, using advanced brain imaging in adults.

What this research studies
When we speak, our brains automatically adjust how they hear our own voice, a process called speech-induced sensory modulation. This helps us monitor our speech and make corrections. This project uses a very powerful brain imaging technique called 7T fMRI, along with EEG, to get a detailed look at which brain areas are active when people speak and listen to themselves. By having participants perform various speech and listening tasks, researchers hope to map the specific brain circuits involved in this process. The goal is to build a clearer picture of how our brains predict and process the sounds we make.
Who could benefit from this research
Good fit: Ideal candidates are healthy adults, 21 years or older, who are interested in participating in brain imaging and speech tasks.
Not a fit: Patients with severe speech impairments or conditions that prevent them from performing auditory-motor tasks may not receive direct benefit from this basic science project.
Why it matters
Potential benefit: Understanding how the brain processes self-generated speech could eventually help people with speech disorders or conditions where speech perception is altered.
How similar studies have performed: Previous studies using other brain imaging methods have shown that the brain's response to self-generated speech is reduced, and this project aims to build on that knowledge with higher resolution imaging.
