The human mind understands the world by interacting with it. When we see an inanimate object that we are familiar with, our mirror neurons instinctively imagine what they could do with that object. A tennis racquet causes our cells to imagine swinging it; a violin causes our cells to imagine playing it.... A separate brain imaging study has shown that our mirror neurons can even be activated by the sound of words. When we say "tennis" or "violin" or "algebra," cells in our motor cortex automatically get excited.
Helpful. But this sentence nails the idea for me:
From the perspective of our brain, learning and doing are just two different verbs that refer to the same mental process.
