Peter Dallos’s research explores the mammalian ear’s inner and outer hair cells. His lab has developed the now widely accepted idea that outer hair cells function as local amplifiers and are responsible for the ear’s sensitivity and frequency selectivity. A few years ago Dallos and his research team identified the molecule prestin, a novel motor protein unique to outer hair cells that helps these cells amplify sound. His current research involves examining the properties of prestin and the influence of modifications in prestin on hearing in mice.
