Is there really that much difference between a genius' brain and a normal persons brain?

The statement blow is correct, although I'm not sure if it was 15 percent. Same as a lot of autistic brains. Identical to a lot of autistic brains, actually.

Why delete it? It's a good topic. :)

Let's see...they chopped up and distributed Einstein's brain, right? And they found out that one part was 15% (?) bigger than an average human's, right? (I'm going totally on memory on this, heh :) ) I guess it'd be a good idea to steal a genius's brain and examine it, so that we can find out what makes geniusness, and make a super-intelligent army to use as international spies. :D

You have the answer in the question: :)

We study genius' brains to see if there is
much difference between a genius' brain and a normal persons brain
