I've read about neuroscience and listen to talks like this one Juan Enriquez: Will our kids be a different species, I'm starting to realize that humans are not all the same, and are instead quite different.

My question is: how "different" are humans from each other from a point of view of neuroscience and neurobiology?

One of the talks at TED.com gave a number that Homo Sapiens is 0.004% different from Neanderthal genetically. Another example given that olympic powerlifters have a certain genetic marker that the general population might not have.

To refine the question: just how different from the perspective of white matter tract anatomy or the distribution of receptors within our neuronal populations are humans of the same haplogroup from one another?

And what do you want to compare? Different skills (e.g. verbal intelligence), different anatomy, different neurochemistry? –  Piotr Migdal Oct 31 '12 at 15:58
I think this is an interesting question, so I tried to refine the requirements to make it answerable, feel free to modify or roll back. –  Chuck Sherrington Aug 2 '13 at 6:24
