So, it's an extraordinarily complicated computing device. Neurons come in three flavors. There are sensory neurons, which take information from the world so as you see me, for instance, there are neurons firing from your retina sending signals to your brain. There are motor neurons. If you decide to raise your hand, those are motor neurons telling the muscles what to do. And there are interneurons which connect the two. And basically, the interneurons do the thinking. They make the connection between sensation and action.
It used to be believed, and it's the sort of thing I would when I taught this course many years ago I would lecture on that neurons do not grow back once you lose them. They... You never get them back. This is actually not true. There are parts of the brain in which neurons can re-grow.
