This is Scientific American's 60-second Science, I'm Steve Mirsky. "It's the truth for all of our senses that they are there to convert physical energy in the surrounding world into electrical responses,

which are the common currency that the nervous system uses." Rockefeller University neuroscientist James Hudspeth.

"So our eyes and the photoreceptors there have to convert light into electricity. Our ears similarly have to convert mechanical vibrations in the air into electrical responses.

And the way this is done is that there are so called hair cells. . . these cells have little microscopic bristles, about a hundred of them, and on the top of each cell,

these bristles vibrate back and forth in response to sound. That sets up an electrical signal that then goes down a nerve fiber and into the brain."

Hudspeth, the University of Wisconsin-Madison's Robert Fettiplace, and the Pasteur Institute's Christine Petit shared the 2018 Kavli Prize in Neuroscience, for their work on the molecular and neural mechanisms of hearing.

Hudspeth and Fettiplace both spoke April 9th at the National Academy of Sciences in Washington D. C. at an event honoring 10 U. S. Nobel and Kavli Prize Laureates. The evening was sponsored by the Kavli Prize and produced by Scientific American. More from Hudspeth:

"And the real question is then is, what happens with these hair cells as they degenerate? We lose them owing to loud sounds, we lose them owing to certain legitimate drugs, we lose just with aging.

And what can be done to repair them so that we can restore hearing?" Robert Fettiplace: "Well, I mean there are two aspects to this, one is that in fact you could try and regrow them.

Almost all hearing loss is due to death of the hair cells or lack of formation of them in the first place. . . the cells along the cochlea are all different.
