Memories of failed attempts and false starts while learning to ride a bike may remain, but it likely all feels natural now. For that, you can thank the intricate circuits comprising your nervous system.
While you practiced balancing on the bike, motor circuits sent commands to your muscles. If you fell and scrapped your knee, sensory circuits carried signals from pain receptors to your brain. Deciding where to ride and watching for cars on the road required more complex circuits.
