Imagine the brain could reboot, updating its withered and damaged cells with new, improved units. That may sound like science fiction, but it's a potential reality scientists are investigating right now. Will our brains one day be able to self-repair? It's well known that embryonic cells in our young developing brains produce new neurons, the microscopic units that make up the brain's tissue. Those newly generated neurons migrate to various parts of the developing brain, making it self-organize into different structures. But until recently, scientists thought cell production came to an abrupt halt soon after this initial growth, leading them to conclude that neurological diseases, like Alzheimer's and Parkinson's, and damaging e...
