Well now I forgot what this topic was about to start with but I must agree that having any brain disorder, like autism, could have an influence of how one perceives things, like when drinking to much or smoking pot.
The white mass in ones brain I am not to familiar with, but I do know that a woman uses the left side of the brain more then the right side. Oh me goodness, I could find loads of information on how the female brain works as compared to the male brain. They are entirely two different spheres of mental processes used for conceiving the world around us. I believe that for one the right side is more for the process of the abstract, mechanical and mathematical dimensions. While the left is used more for texture hues and colors as well as the ability of intuition.
This does not mean that a male of female can't equally and adeptly access the right and left side of the brain reciprocally. It is just more common that we mostly only mostly use one side or the other side more consistently, depending on gender. It does not mean that a male will not see or conceive that very same information as a woman does, but we do see and interpret it differently.
I beleive using the color scale to explain might simplify it some. You would find that a female will see with a much more diverse and complex reality as well as with an abundant with colors in perceptions. This is believed to be that for the reason that a male will compartmentalises all their thought feelings and experiences, while women are all in one big box without separators, well something like that, if anyone is curious enough I could go fetch a couple of web sites on the subject.
The brain is a complex organism and only in the past thirty years have they made any real inroads on the study of the human brain.
