I thought no woman would ever have the brains to see it.

Maybe there's really an image there in your mirror, but the human brain just won't see it.

But his evil brain was seeing its chance of escape.

Even his dull brain saw the wisdom of Slick's choice.

But even his poorly responding brain could see that he would never make it.

A dull brain sees things not always as they are.

The idea is that the brain sees things as a whole.

Will my brain make the one jump and see all?

"But couldn't that just be what a normal person's brain sees while it's still alive after the rest of the body dies?"

Basically, it is a method of training hands to quickly sketch what the brain has already seen.
