If you've ever seen a human brain, it's obvious that the two hemispheres are completely separate from one another. And I have brought for you a real human brain. [Thanks.] So, this is a real human brain... And when you look at the brain, it's obvious that the two cerebral cortices are completely separate from one another. For those of you who understand computers, our right hemisphere functions like a parallel processor. While our left hemisphere functions like a serial processor. The two hemispheres do communicate with one another through the corpus collosum, which is made up of some 300 million axonal fibers. But other than that, the two hemispheres are completely separate. Because they process information differently, each hemisphere thinks about different things, they care about different things, and dare I say, they have very different personalities. [Excuse me. Thank you. It's been a joy.]
Our right hemisphere is all about this present moment. It's all about right here right now. Our right hemisphere, it thinks in pictures and it learns kinesthetically through the movement of our bodies. Information in the form of energy streams in simultaneously through all of our sensory systems. And then it explodes into this enormous collage of what this present moment looks like. What this present moment smells like and tastes like, what it feels like and what it sounds like. I am an energy being connected to the energy all around me through the consciousness of my right hemisphere. We are energy beings connected to one another through the consciousness of our right hemispheres as one human family. And right here, right now, all we are brothers and sisters on this planet, here to make the world a better place. And in this moment we are perfect. We are whole. And we are beautiful.
My left hemisphere is a very different place. Our left hemisphere thinks linearly and methodically. Our left hemisphere is all about the past, and it's all about the future. Our left hemisphere is designed to take that enormous collage of the present moment. And start picking details and more details and more details about those details. It then categorizes and organizes all that information. Associates it with everything in the past we've ever learned and projects into the future all of our possibilities. And our left hemisphere thinks in language. It's that ongoing brain chatter that connects me and my internal world to my external world. It's that little voice that says to me, "Hey, you gotta remember to pick up bananas on your way home, and eat 'em in the morning." It's that calculating intelligence that reminds me when I have to do my laundry. But perhaps most important, it's that little voice that says to me, "I am. I am." And as soon as my left hemisphere says to me "I am," I become separate. I become a single solid individual separate from the energy flow around me and separate from you.
And this was the portion of my brain that I lost on the morning of my stroke.

Dr Jill Bolte Taylor is the woman I'm basing my fact project on. There's one week to go and I have not gotten very far at all. But it'll come to me. I'm thinking of doing the narrative as a series of illustrations that become less and less clear, and annotations that become clearer and clearer. I find it interesting that Bolte Taylor would never be able to share to notion of a collective consciousness (right hemisphere) without language (left hemisphere).
For those of you who don't have 20 minutes, here's the prelude to Bolte Taylor's story:
