And the neat thing about this is that um we didn't have to do something like stick an electrode into these muscles because they're attached to the bones and attached to the eardrum. And so if they were being manipulated by a top down signal from the brain, they would tug these bones and that that would tug the eardrum. And when the eardrum moves, normally it moves in response to sound, but if it moves in the absence of sound, it's going to make a sound.
