A protein that's a key part of the sound-to-ear-to-brain conversion
process has been ID'd by Scripps Research Institute researchers. The
scientists say the protein is a part of the mechanism in the ear canal
that converts sound waves to electrical impulses that are transmitted to
nerve cells. In lab tests, researchers were able to place functioning
TMHS protein into the ear cells of newborn deaf mice, restoring their
hearing. The protein may lead to improved treatments for hearing
disorders.
