Rethinking how our brains build the neural networks underlying motor memories
For every motor skill you've ever learned, whether it's walking or watchmaking, there is a small ensemble of neurons in your brain that makes that movement happen. Our brains trigger these ensembles—what we sometimes call "muscle memories"—to get our bodies cooking, showering, typing, and every other voluntary thing we do.
