They are, but with 60% fat and 75% water, statistically, the brain’s mostly a fat sponge filled with water.
Of course the WAY the fat is deposited, along with the proteins and salts and neurochemicals and all the fascinating networks within and the minute processes that take places simultaneously is what’s more fascinating than a fatty sponge sloshing water around. Oh, with a 9v battery attached. tongue emoticon
I know – I just like teasing when it comes to the brain. I see the brain as a central hub of a wider network that also ultimately includes our environment. Rather than a biological supercomputer, I see more chaotic networks with emergent properties which generate systems which function in a supportive manner not only for the organism but in concert with its environment, which includes other people and their systems.
And… it strangely looks like this when disconnected from its network, sliced in half and preserved.
Of course to me, that’s not a picture of 1/2 a brain. Brain’s only a brain when it’s functioning as a brain. When it sits like that, it’s just this blob of preserved fatty proteins.
Very cool – the closest I came to that is dissecting a frog. I was disappointed when I got to the brain and it was just this little lump of wet fat: which is probably where my basic notion of “what the brain really is” came from . So much for biology class tongue emoticon
