    The cerebral cortex (outer layer) is referred to as gray matter apparently for a reason but why in text books and photographs is it usually a pinkish fleshy color? I grew up thinking the brain was this color: http://upload.wikimedia.org/wikipedi...generation.jpg

    It's grey compared to the white matter underneath and also probably because it would first have been named so by dissection on a dead body where the brain would definitely appear more grey. (the grey matter at least)

    (The grey matter is the part of the brain containing the cell bodies of the neurons, hence the name! underneath is the white matter which is mostly synapses and all the other parts.)

    heres an answer I read somewhere else:

    pink from the numerous blood vessels through it. Some areas with a lot of myelin are more whiteish.
    If you have a grey brain you are dead and maybe somebody dunked your brain in formalin or any other fixative. Not a desirable stage to be in. Sorry for all those people with grey brains here.
    As the anatomists got to see somebody elses brain mainly fixed in formalin the term grey and white matter (to distinuish cell and fiber parts) comes from there. It doesn't have much to do with how the brain looks alive.

    Zythum's right. It's pink. It doesn't become grey until after death.

    People have been able to drill holes through live skulls for some time now, whilst not killing the individual. And besides, the technical name of the brain is not based on its living/dead status. ‘Grey matter’ is a slang term more-or-less, and is used as simply a reference. We can still use it as a slang reference for the brain without having to chuck all our knowledge out the door and start assuming that it is actually grey.

    After all, how many tree trunks are actually brown?

    Well, to go so far as to figure out that there's two different kinds of 'matter' that compose the brain, they'd have to do far more than drill a few holes.
    Whence comes this logic: no evidence = false?

    If someone stabbed you in your brain. you actually wouldnt feel it at all.
    The hand of time rested on the half-hour mark, and all along that old front line of the English there came a whistling and a crying. The men of the first wave climbed up the parapets, in tumult, darkness, and the presence of death, and having done with all pleasant things, advanced across No Man's Land to begin the Battle of the Somme. - Poet John Masefield.

    No, you wouldn't. However, you would still be one dead son of a gun :wink:.

    I believe that the brain in a living human would be pink, while the brain is someone who has been deceased for a set period of time would be grey, due to lack of blood circulation. There is a video from Youtube where you can see and actual brain. The woman explains the rest, but the colour of the brain in the video is due to the fact that it has very recently been inside a head. Just search into Youtube, the unfixed brain. It should be from the University of Utah.

    The brain sees itself. It wants to see itself like the color it is. So we see it pink, or grey, as the brain sees itself. It could actually be any color. Which the brain have said, let that be pink, or grey. Kinda philosophical.
    The past teaches, the present watches and the future learns.

    Though religion is a concept that simply can not be ignored. The fact that a deity could stand idly by when one part of his creation slaughters another part, simply for his namesake, is a mystery i doubt theologist would dare touch.
