Cochlear Neurotransmission Group

The Cochlear Neurotransmission Group studies the generation and propagation of neural signals in the inner ear. Our laboratories use biophysical, electrophysiological, molecular biological and histological methods to determine fundamental molecular mechanisms by which neurotransmitters are released from primary sensory cells (‘hair cells’) to excite second order neurons carrying information to the brain. We apply these same techniques to study inhibitory feedback produced by brain neurons that project to and regulate the sensitivity of the cochlea.

Our studies concentrate on the properties of voltage and/or ligand-gated ion channels and transporters expressed in hair cells, neurons and supporting cells of the cochlea. Ion channels, neurotransmitter receptors and transporters are therapeutic targets for the treatment of virtually all diseases of the nervous system.

Discoveries from this laboratory will help advance therapeutic approaches to hearing loss by identifying these essential molecules and defining their functional roles in the cochlea.
