I was talking with Elan, my roomate who doesn't live with me, last night. We were discussing the idea that you can actually figure out things about the way your cells might work just by feeling it. I was thinking that maybe our brains are somehow holographic detectors of crystaline structures created by our trillions of cells repeating the same structures over and over and over again. Who knows. At the very least, I've got an idea for a sci-fi novel.
Then we were thinking this - if our conciousness is just projection of many many cells living together in our bodies, then 'we' are really just a side effect of our cells. And really why are we so afraid of dying? Our cells never die. Well OK, some of them do, but this is happening all of the time! And some of them are always passed on, our cells really grow as a continuum through time - father's cells mix with mother's cells out of which baby's cells grow. 'We' are just along for the ride on this never ending blob of cells. It makes me a think of a lava lamp, balls of wax rising and breaking off from other balls, forever and ever.
Undeniable though, is this big digital brain sitting on top of all those cells, and it arguably has a life of its own. And this brings us to one of my favorite topics of philosophical debate - how much of our self is in our bodies and how much is in our brain? Body conciousness may be a completely different but just as important a phenomenon as brain conciousness.
But then there is a question in neuroscience about how digital the brain actually is. There is new research that is starting to show the importance of the glial cells in neuronal function. There are 100 times as many glial cells as neurons in your brain. They don't 'fire' like neurons do, but they are chemically and mechanically connected to the neruons that are storing memories and making your heart beat. Perhaps the glia somehow represents the mind-body interface in the central nervous system and a similar dichotomy occurs between your body and the peripheral nervous system.
However, the most important question remains - how many times a week do you clean your ears? No seriously, let me know and I'll plot the results. And if it is different at different times of the year (winter, summer, etc) that is good to know to. For scientific progress!!
