Understanding How the Brain Processes Speech Sounds

Human Auditory Cortex Physiology

NIH-funded research University of Iowa · NIH-11005043

This project aims to understand how different parts of the brain work together to help us hear and understand speech, especially in patients undergoing brain surgery.

What this research studies

This project explores how the brain predicts and processes speech sounds, using a model called "predictive coding." Researchers will use special methods, including direct recordings from the brain and non-invasive techniques, in patients who are already having brain surgery. They will also gently stimulate parts of the brain to see how it affects speech perception. This approach helps overcome challenges in understanding how the brain's speech network functions. The goal is to pinpoint where and how speech information is represented within this complex network.

Who could benefit from this research

Good fit: Ideal candidates are neurosurgery patients who need chronic intracranial electrodes placed as part of their medical care.

Not a fit: Patients not undergoing neurosurgery requiring intracranial electrode placement would not directly participate in this specific research.

Why it matters

Potential benefit: If successful, this work could lead to a better understanding of speech perception, potentially helping patients with acquired brain injuries or other conditions affecting speech processing.

How similar studies have performed: This project uses novel combinations of experimental methods to address long-standing challenges in the field, suggesting a unique approach.
