 Then in people with Parkinson's disease, which is not enough dopamine, they can actually give them a little bit more. With people with epilepsy, someone with temporal lobe epilepsy, they can actually use this nanotechnology and program it to go to parts of that brain and start then attaching itself and rebuilding and creating new pathways. So if there's a damage to the brain, which is causing the seizure, we can bypass that and go to other ways. And all this sounds amazing.
