Well, we know that the outside of the brain uses more energy (by volume) than the inside. Plus, the evolutionary advantage of the wrinkles in the brain seems to be to increase surface area (of the outside, of course).
Disclaimer: I'm no neuroscientist but I did take an introductory psych course this one time.
- innocentoldguy 11y agoInteresting you say that. My wife always claims I have a brain, but it is free of wrinkles. She's probably right.

For instance if you're going to make a highly connected multiple-cpu computer it helps to keep the wiring as short as possible and the 'hot' parts on the outside (so they can cool). The most striking example of this design is the old CRAY machines. https://en.wikipedia.org/wiki/Cray-1 https://en.wikipedia.org/wiki/Cray-1
