And yet we will still get ones that demand that men and women are the same. I am all for equality, but saying that is like saying a sports car and a truck are the same.

Flip side, I do agree that this is good information that will help with development and medication.

Not sure about a demand for 

I believe the logical/legal requisite is that they be treated equally with men (no gender discrimination) in the work place and under the law. 

Yep, which I agree with. Its more of the ones that are demanding that men and women are carbon copies. We are not, as noted with brain scans. Its these that drive me up the wall.

Somethings take science to reveal what 'should' be obvious. Equality is fine but the differences between genders exist for a reason. Women are natural home makers, men are the providers. We go out and get the stuff and the women organize it, the basic premise. It is ingrained in the species to insure survival. Hunter/gatherers......how we began and how we still are albeit in a more 'modern sense'. Probably why its called' A no brainer'.

Do we need research for something that we all know.

You don't "know" it's true or false until you prove it. Until then, you "suspect" it might be true or false. Example? The flat earth was accepted as true until proven false.

Besides, had you read the OP's last paragraph, you'd see why the research might prove a critical advancement to the treatment of illnesses of the central nervous system in men and women. For that reason alone, the research was very important.

Flat earth was never accepted by everybody at all for start.

In terms of research yes I agree. The more we learn about those differences the better to pattern what is needed to overcome debilitating conditions that interfere with what should come naturally......if that makes any sense. 

I guess I don't need to feel so bad about forgetting to put my pants on this morning.   (I actually did that, at least I didn't go outside.)

Looking at the brain maps, it also might explain the common perception that women are so more inclined to talk about their feelings than men are.  [Now stop wanting me to do that.]

The female brain looks scrambled...

I wonder how common it is for a male to have a brain wired like a woman, or vice-versa. 

Exactly like that, I am sure, is a rarity but those are averages as some males are more social then your average woman and some females are more hunterious then your average male.

There's a lot of 'grey' in between.
