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.

The brain is the most complicated organ in the universe. We have learned a lot about other human organs. We know how the heart pumps and how the kidney does what it does. To a certain degree, we have read the letters of the human genome. But the brain has 100 billion neurons. Each one of those has about 10,000 connections.
With its billions of interconnected neurons, whose interactions change from millisecond to millisecond, the human brain is an archetypal complex system.
The human brain is probably one of the most complex single objects on the face of the earth; I think it is, quite honestly.
The human brain has 100 billion neurons, each neuron connected to 10 thousand other neurons. Sitting on your shoulders is the most complicated object in the known universe.
The brain is a complex biological organ possessing immense computational capability: it constructs our sensory experience, regulates our thoughts and emotions, and controls our actions.
We have about 100 million cells interconnected in our brains. They communicate with one another through electrical signals.
We cannot experimentally map out the brain. It's just too big. In a piece of the brain the size of a pinhead there are 3,000 pathways like a city with 3,000 streets.
What we find is that our brains have colossal things happening in them all the time.
It's not even known how many kinds of cells there are in the brain. If you were looking for a periodic table of the brain, there is no such thing. I really like to think of the brain as a computer.
You can't imagine how much detail we know about brains. There were 28,000 people who went to the neuroscience conference this year, and every one of them is doing research in brains. A lot of data. But there's no theory. There's a little, wimpy box on top there.
