I will read the article.
However I'm very skeptical of statements that link gross features of the physical brain and displayed characteristics. Mainly because the programming is in the software, not so much in the hardware.
For example, did you know that intelligence is associated with larger brains, statistically? However, a larger brain doesn't mean a person is more intelligent. Correlation isn't causation (say that three times). You can beat a drum every time there is an eclipse, and I guarantee that if you do that the sun will come back.
Secondly, genius is as much a cultural phenomenon as it is an individual. I've known a few geniuses, I'm considered one by some, but I've never done anything especially noteworthy. This is because I didn't have the circumstances or opportunity for that.
I've studied Einstein a bit as I idolized him somewhat during my physics days. I think he was a genius, but actually not too bright. He needed considerable help with tensor calculus, and never wrapped his head around quantum mechanics. But he was crazy enough to consider the only solution to Michaelson-Morley would be time dilation.
Obvious in hindsight, but it would take an oddball INTP to see it at the time.
