Because it's full of cells

Actually, the cortical folding makes the brain more efficient, because it can increase the surface area of the brain and the amount of neurons within it. The folding is called gyrencephalization... the ridges are called gyri, while the depressions are called sulci... By the way, the more complex the animal the more folding is displayed...

Well, thanks, Buddy... have a really nice trip!

The lady with whom I trade gardening, cooking and house maintenance for sleeping priveleges tells me (constantly) that I'm a walking compendium of absolutely useless facts...
