Dr. Rubio has studied the synaptic circuitries in the cochlear nucleus, the cerebellum and the hippocampus as well as the structure the Organ of Corti in the cochlea.By taking a multidisciplinary approach, she developed expertise in functional assessment of hearing function, anatomy, ultrastructure, quantitative immunolabeling of a variety of proteins at the light and electron microscopic level and biochemistry. A long-term goal of Dr. Rubio’s research is focused on determining the molecular mechanisms that endow cochlear nerve fibers with temporal fidelity. These mechanisms are still largely unknown but are in place at central auditory nerve synapses and at the inner hair cell synapse in the cochlea. Dr. Rubio’s second research interest is to determine the role of glial cells in auditory function. In particular, the relationship (molecular and structural) of astrocyte processes to auditory nerve synapses in the normal hearing and in the hearing impaired.
