I think my characters with my fingers, I think my characters with my guts. But when I say I think them, that is what I do, I feel them with the sympathetic neurons and I work out with my brain what it is that I am trying to write about, or I can't do it.
For me, consciousness is the most interesting unsolved problem of science, and, in fact, we may never know what it is about a particular arrangement of neurons that gives rise to consciousness. Our consciousness, like the air we breathe or like the passage of time, is central to our existence as intelligent beings.
Life and consciousness are the two great mysteries. Actually, their substrates are the inanimate. And how do you get from neurons shooting around in the brain to the thought that pops up in your head and mine? There's something deeply mysterious about that. And if you're not struck by the mystery, I think you haven't thought about it.
Neurons are living cells with a metabolism. And they need glucose in order to function. Glucose is the fuel of the brain, just like gasoline is the fuel of your car.
There's an ancient connection between movement and music. Most languages don't make a distinction between the words 'music' and 'dance.' And we can see that in the brain. When people are lying perfectly still but listening to music, the neurons in the motor cortex are firing.
A typical neuron makes about ten thousand connections to neighboring neurons. Given the billions of neurons, this means there are as many connections in a single cubic centimeter of brain tissue as there are stars in the Milky Way galaxy.
Your brain is built of cells called neurons and glia - hundreds of billions of them. Each one of these cells is as complicated as a city.
Because many squid have brain nerve fibres that are hundreds of times thicker than those of humans, neuroscientists have long used them for research. These nerve fibres have led to so many breakthroughs in the study of neurons that many scientists joke that the squid should receive a Nobel Prize.
Throughout our lifetimes, we are constantly regenerating new brain cells in the hippocampus, a process called neurogenesis. New stem cells are constantly being born in the hippocampus that ultimately differentiate into fully functional neurons.
An illustration I use to get people to understand it is this: I'll ask major corporate audiences: Why don't you just take all your traditional beliefs about organizations, and apply them to the neurons in your brain?
