Abstract

? DESCRIPTION (provided by applicant): Cochlear implants stimulate the auditory nerve using stimuli that minimize the release of toxic electrochemical byproducts and damage associated with metabolic stress of the stimulated neurons. However, these guidelines were based on acute stimulation of cortical neurons and thus do not reflect the safe levels of stimulation for us in a cochlear implant. This application will establish safe stimulation limits specifically for cochlear implants using chronic electrical stimulation. The project will use clinical implants and electrode fabrication technology to manufacture customized electrode arrays for this research with carefully defined surfaces as sma..
