Is it true that when you learn something new, you get a wrinkle on your brain?

Question

I have heard this saying all the time and I was wondering if it's really true or not. It's just really interesting to mee if it is. :D

Answer 1

uuuhhh....I'm thinking...no....oh wait, I just got a new wrinkle....holy c**p now I'm brilliant....WOWEEE!

Answer 2

No. It's complete horseshit.

Answer 3

only if it's "long term memory" and only if you get enough sleep; the folds in the brain add to its surface area and therefore increase the amount of gray matter and the quantity of information that can be processed.
