![]() That was a really pretty significant thing.īefore that, the brain was thought to be largely immutable, sort of fixed, and really measured only by its inputs and its outputs, a black box of sorts. What we've come to understand over the last decade is that even outside of those two conditions - just a normal life without an injury or as an adult - you can still grow new brain cells. ![]() And at that point, the brain may start to either recruit new brain cells or even grow new brain cells. We long believed that brain cells - neurons - would only sort of continue to develop or go through this neurogenesis (new brain cell development) process at two different times, really: when you were very young and still developing your brain as a baby or if you've had some sort of injury. On how the thinking about brain cell regeneration has changed recently Keep Sharp, by Sanjay Gupta Simon & Schuster Gupta's new book about the brain, Keep Sharp, explains some of the latest research, debunks myths and offers practical advice on improving cognitive function. "It is sort of the use it or lose it phenomenon when it comes to the brain." Your ability to process, understand and apply knowledge "can actually get sharper, can get better as you get older," he says. No matter how old you are, it's never too late to develop new brain pathways, Gupta says. If you wear a necktie, close your eyes and practice tying it in the dark. If you're right handed, try eating with your left hand - or vice versa, if you are a lefty. ![]() The new skill can be simple, Gupta notes. "We want to constantly be using new paths and trails and roads within our brain." "The act of experiencing something new - or even doing something that's typical for you, but in a different way - can all generate these new brain cells," says Gupta, a practicing neurosurgeon and associate professor of medicine at Emory University School of Medicine. Sanjay Gupta says that will also improve your brain health. Interested in learning a new skill in the new year? CNN chief medical correspondent Dr.
