Neuroscience How does muscle memory work?

Just curious. The only thing I really know about it is that sleeping reinforces it.

Not mine, also. But maybe by a shorter shot! 😉 Definitely there's no way we eventually bypass cerebral connections. There definitely are reflexes that follow the path you've described. But "muscle memory" implies practice/learning. Those will always go all the way to the brain and back, I believe.
