 While there, Tasaki and his colleagues demonstrated how vibrations that occur in the cochlea in response to sound are translated into electrical signals that the brain can interpret.This effort led to the development of the field of audiology, indirectly providing the basis for diagnosing and treating many hearing disorders.Tasaki began his career at the National Institutes of Health in 1953, at NINDS, then called the National Institute of Neurological Disorders and Blindness.
