How do our bodies remember?

MIT Technology Review 

How do our bodies remember? The more we move, the more our muscle cells begin to make a memory of that exercise. Explains: Let our writers untangle the complex, messy world of technology to help you understand what's coming next. "Like riding a bike" is shorthand for the remarkable way that our bodies remember how to move. Most of the time when we talk about muscle memory, we're not talking about the muscles themselves but about the memory of a coordinated movement pattern that lives in the motor neurons, which control our muscles. Yet in recent years, scientists have discovered that have a memory for movement and exercise.
