I know you need it. I guess what I meant was an exact use for it. As in everything it does, and nothing it doesn't. I do realize that we do infact need it, atleast during our physical life.
you would not gladly remove my brain, please keep it serious, and confront me on a serious level; I would greatly apreciate that, thank you.
hey wombat I am sorry to hear that. My great grandfather died of a stroke a few years ago. He was 86 or around there. My great grandma (on the other side) also died of a stroke she lived 5 years after it, but we couldn't understand her slured speach. That was the hardest part.
I think the rat study atleast shows that the brain is not static,but dynamic in where it stores info or that life itself is highly adaptable. One thing you should consider is that brain damage affects everyone differently. Some people who lost one whole hemisphere of there brain obviously can't see very well, but they still have there whole memory/personality.
Some results support that the brain has certain "sectors" for certain purpouses. Some results show that all areas of the brain can do any part, but are less "intuned" to do it. I think a lot of it has to do with your life experience, rather than what you are born with.
There were different tests (on humans) where they put to sleep only certain parts of the brain while keeping the test subject consious. They would then have the participents sing, and do arithmetic and other "area" specific things. Some involved sight. By putting the left side "asleep" the right eye would be "blind" and they put up words that crossed both left and right and the people were supposed to read them. They read only the half that was on the same side as the "asleep" part of there brain.
At the same time they were able to remember everything that had gone on in there lives (long term memory) and were able to remember frases and number sequences shortly after being told them (short term memory)

Also, I wonder what kind of memories rats have?
the rats memory was of a maze. The way to get through it to the cheese or whatever. their speed at getting through the maze was proportionate to the size of the brain matter left intact. It did not, however, matter where in the brain they took it from. What this suggests to me is that the whole brain is used for memory in a very dynamic style unlike computers. That the more brain tissue you have the better.

I guess that cutting a small portion of the rat's brain will not have an effect on it's whole memory, but maby it will on a small part of it.
However, they took the peices from different parts of each rat so the part that gets left out would inevitably(sp?) be the part that knows the maze in some rats. They had control rats too. Those rats had there head cut open with no parts removed, so that all rats would have that same trauma, or atleast as close as possible.

However you look at it, you cannot ignore the fact that brain damage affects memory.
yes, i agree, but sometimes the effect can be negligable, sometimes where lots of damage is present. It's rare, but it happens. most cases you are absolutely right.
I don't want to say anything in certainty. Let me make that clear. I just want to point out that the brain is less understood the more we study it. The human brain is said to be the most complex thing in the universe. not based on hard facts of course.
anyway interesting topic, and thank you for the replies.
