After you’re an adult, your brain stops growing, right?
Wrong. Everybody thought that, until we got more advanced technology, and so then, we researched more about brains, and found out that your brain never keeps growing, even when you’re an adult. Turns out, every time you learn a new thing, or even just think some thoughts, your brain changes. There are two types of changes that can happen. A short term chemical change, a long term structural change. A short term change is when your brain adjusts how much your neurons are connecting, so it might give you a temporary boost at something. This is what happens when you think you are getting the hang of a new skill but then the next day you’re not as good again.
Everybody’s brains are different, which is why some learning methods are better than others for a specific person. That is also some people learn faster than others, and while a person might be good at something, he/she might not be as good at another thing. But that is not what shapes a brain the most. The thing that shapes the brain the most are your habits. Everybody has different habits, and that structures their brain. Right now, we are still researching, and there is much more to be found about brains, and how they grow, but for now, we have realized that many things that we thought before about how brains grow are wrong, and that there is still much to learn.
