 That's exactly right. Even when I was in medical school 15 years ago, we were mostly taught that once your brain is developed, when you're an adult like 20 or so, that's it. Your brain is done developing. But it's definitely not the case in certain areas like the hippocampus or memory center. The adult brain can grow neurons mostly throughout life, which is how we make memories. We make new neurons in that center, and we can make new connections there.
