Neuroscience de l'audition
Principal Investigator: Melissa Saenz
How does the brain hear? The Auditory Neuroscience Group uses non-invasive brain imaging in humans to investigate (1) how sound information is processed by human auditory cortex and (2) how this processing is altered in audioneurological dysfunction. Our research applies to Clinical Neuroscience (tinnitus, cochlear implants, age-related hearing disorders) as well as Fundamental and Cognitive Neuroscience (auditory systems, language, music).

In the primary auditory cortex neighboring sound frequencies are processed by neighboring points in the brain - an orderly arrangement called tonotopy. Using high-resolution functional MRI at 7 Tesla, we can image this cortical organization, non-invasively and in only a few minutes, in volunteers with normal hearing and patients with auditory disorders.
