“When you are learning, important changes take place in your brain, including the creation of new connections between your neurons.
This phenomenon is called neuroplasticity.
The more you practice, the stronger these connections become. As your connections strengthen, the messages (nerve impulses) are transmitted increasingly faster, making them more efficient.
That is how you become better at anything you learn whether it is playing football, reading, drawing, etc.
This is very similar to what happens in your brain—when you stop practicing something, the connections between your neurons weaken and can ultimately be dismantled or pruned. “
