Hearing is the gateway to verbal communication. It commences with the capture of sound energy by the ear's sensory receptors, called hair cells, which convert that energy into electrical signals that the brain can interpret. Unique among our sensory receptors, the hair cell is not a passive recipient of stimuli, but instead uses an active process to enhance the input it receives— amplifying acoustical stimuli, sharpening frequency selectivity, and broadening the range of audible sounds. When this active process becomes unstable, most ears can even emit sound! Dr. Hudspeth will discuss the ear's operation and efforts to restore hearing by regenerating hair cells and then join Emmy Award-winning journalist Frank Sesno, Director of the School of Media and Public Affairs at the George Washington University, for a discussion of his life and work.
