Jill Bolte Taylor is an intellectual and a neuroanatomist. In this TED talk entitled My Stroke of Insight, she describes how human brains define us and connect us to the world and to one another. On the morning of December 10 1996, she had a massive brain stroke which had deepened her understanding more about the brain… Here is the transcript of the TED talk…

 

Jill Bolte Taylor – Neuroanatomist

I grew up to study the brain because I have a brother who has been diagnosed with a brain disorder, schizophrenia. And as a sister and as a scientist, I wanted to understand, why is it that I can take my dreams, I can connect them to my reality, and I can make my dreams come true — what is it about my brother’s brain and his schizophrenia that he cannot connect his dreams to a common, shared reality, so they instead become delusions?

So I dedicated my career to research into the severe mental illnesses. And I moved from my home state of Indiana to Boston where I was working in the lab of Dr. Francine Benes, in the Harvard Department of Psychiatry. And in the lab, we were asking the question – What are the biological differences between the brains of individuals who would be diagnosed as normal control, as compared to the brains of individuals diagnosed with schizophrenia, schizoaffective, or bipolar disorder?

So we were essentially mapping the microcircuitry of the brain, which cells are communicating with which cells, with which chemicals, and then with what quantities of those chemicals. So there was a lot of meaning in my life because I was performing this kind of research during the day. But then in the evenings and on the weekends I traveled as an advocate for NAMI, the National Alliance on Mental Illness.

But on the morning of December 10 1996 I woke up to discover that I had a brain disorder of my own. A blood vessel exploded in the left half of my brain. And in the course of four hours I watched my brain completely deteriorate in its ability to process all information. On the morning of the hemorrhage I could not walk, talk, read, write or recall any of my life. I essentially became an infant in a woman’s body.

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.

So, this is a real human brain. This is the front of the brain, the back of the brain with a spinal cord hanging down, and this is how it would be positioned inside of my head. 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.

Right hemisphere – Brain

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.

Left hemisphere – Brain

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 got to remember to pick up bananas on your way home, and eat them 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.

On the morning of the stroke…

And this was the portion of my brain that I lost on the morning of my stroke. On the morning of the stroke, I woke up to a pounding pain behind my left eye. And it was the kind of pain, caustic pain, that you get when you bite into ice cream. And it just gripped me and then it released me. Then it just gripped me and then released me. And it was very unusual for me to experience any kind of pain, so I thought OK, I’ll just start my normal routine.

So I got up and I jumped onto my cardio glider, which is a full-body exercise machine. And I’m jamming away on this thing, and I’m realizing that my hands looked like primitive claws grasping onto the bar. I thought “that’s very peculiar” and I looked down at my body and I thought, “whoa, I’m a weird-looking thing.” And it was as though my consciousness had shifted away from my normal perception of reality, where I’m the person on the machine having the experience, to some esoteric space where I’m witnessing myself having this experience.

And it was all very peculiar and my headache was just getting worse, so I get off the machine, and I’m walking across my living room floor, and I realize that everything inside of my body has slowed way down. And every step is very rigid and very deliberate. There’s no fluidity to my pace, and there’s this constriction in my area of perceptions so I’m just focused on internal systems. And I’m standing in my bathroom getting ready to step into the shower and I could actually hear the dialog inside of my body. I heard a little voice saying, “OK, you muscles, you got to contract, you muscles you relax.”

And I lost my balance and I’m propped up against the wall. And I look down at my arm and I realize that I can no longer define the boundaries of my body. I can’t define where I begin and where I end. Because the atoms and the molecules of my arm blended with the atoms and molecules of the wall. And all I could detect was this energy. Energy. And I’m asking myself, “What is wrong with me, what is going on?” And in that moment, my brain chatter, my left hemisphere brain chatter went totally silent. Just like someone took a remote control and pushed the mute button and — total silence.

And at first I was shocked to find myself inside of a silent mind. But then I was immediately captivated by the magnificence of energy around me. And because I could no longer identify the boundaries of my body, I felt enormous and expansive. I felt at one with all the energy that was, and it was beautiful there.

Then all of a sudden my left hemisphere comes back online and it says to me, “Hey! we got a problem, we got a problem, we got to get some help.” So it’s like, OK, OK, I got a problem, but then I immediately drifted right back out into the consciousness, and I affectionately referred to this space as La La Land. But it was beautiful there.

Imagine what it would be like to be totally disconnected from your brain chatter that connects you to the external world. So here I am in this space and any stress related to my, to my job, it was gone. And I felt lighter in my body. And imagine all of the relationships in the external world and the many stressors related to any of those, they were gone. I felt a sense of peacefulness.
