Neuroplasticity

Neuroplasticity is like when your brain keeps changing and growing. It's like a muscle - you can train it and it gets stronger over time. When you learn something new, that knowledge can stay in your head permanently. This is because your brain changes and adapts the way it works so it can remember the new information. Neuroplasticity also helps your memory to stay sharp. That way you can remember new things that you learn.
