The inner ear is connected to the brain by  two kinds of sensory neurons carrying information about incoming sound as well as two seperate feedback pathways sending control signals from the brain back to the ear. Professor Liberman's research aims to understand why four different neuronal pathways are needed and what role each plays in hearing and deafness. We use a variety of approaches from systems neuroscience to cell and molecular biology.
