    Exclamation Itching

    It's official -- this article on itching blew my tiny prosimian mind.

    The images in our mind are extraordinarily rich. We can tell if something is liquid or solid, heavy or light, dead or alive. But the information we work from is poor—a distorted, two-dimensional transmission with entire spots missing. So the mind fills in most of the picture. You can get a sense of this from brain-anatomy studies. If visual sensations were primarily received rather than constructed by the brain, you’d expect that most of the fibres going to the brain’s primary visual cortex would come from the retina. Instead, scientists have found that only twenty per cent do; eighty per cent come downward from regions of the brain governing functions like memory. Richard Gregory, a prominent British neuropsychologist, estimates that visual perception is more than ninety per cent memory and less than ten per cent sensory nerve signals.

    I actually read all of the article, and I must say that it was pretty interesting.

    I actually read half of the artcle and I must say it was pretty interesting.

    I remember reading something a few years ago talking about how pain and itching can cancel each other out. A person can have an injury that hurts, but when he gets morphine, the pain stops and the itching can start, but when the pain returns, or if scratching causes pain, the itching subsides in relation to the increase in pain. Something like that.

    I really have a hard time swallowing some of that article, but I guess I must. How the hell do you scratch THROUGH your skull? The skull is one of the thickest, strongest bone structures in a human body.

    Hmm, depends on which part of the skull, doesn't it? Obviously, as any kid who played soccer knows, the front of your skull is tough stuff. The sides? Not in the same league. But even given that, yeah, scratching through your skull would take some doing.

    Frankly, I was more interested in the stuff about perception and brain-filtering.
