We are always dancing

Even though I am a thoroughly clumsy dancer (at those rare moments I compelled to dance--and even then, I am not as bad as Jon), my outer ear cells are skilled at dancing. Scientists cannot come up with a better term for describing how the cells of our outer ear propel and amplify sound before it enters the innermost parts of our ears. They dance to coax the sound waves to expand as they transform into electrical signals, so that when the brain is ready to translate what it receives, it has the best copy available, so to speak.

Thanks to D. for bringing this to my attention.
