The Role of the Cerebral Cortex in Cognitive Processes

In the house, there's no fat surrounding it because there's no signal sent. But once you're on the road, that's where you've got the fatty Mylon sheath that surrounds... That's dangerous for the cars. It's like the bitumen. So at the end of the day, white matter, they're the highways covered in Mylon,. The gray matter are simply the bodies. And so most of the cerebrum are the lobes - 80% of those neurons sit just in that cortex.
