A Quote by Paul Allen
We know a certain amount about neurons. You can do fMRI and watch parts of the brain light up. But what happens in the middle is poorly understood.

There are billions of neurons in our brains, but what are neurons? Just cells. The brain has no knowledge until connections are made between neurons. All that we know, all that we are, comes from the way our neurons are connected.
Brain cells are normally not sensitive to light. So by introducing light-sensitive proteins into specific types of neurons, we can now selectively control that specific type of neuron by shining light in the brain.
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.
Unlike the heart or kidney, which have a small, defined set of cell types, we still do not have a taxonomy of neurons, and neuroscientists still argue whether specific types of neurons are unique to humans. But there is no disputing that neurons are only about 10 percent of the cells in the human brain.
You know, you get to a certain age, 45, 50, I don't know when it happens, I said, 'Jesus, all I got is a certain amount of time. Maybe I should think about using it a little better.'
There are 100 billion neurons in the adult human brain, and each neuron makes something like 1,000 to 10,000 contacts with other neurons in the brain. Based on this, people have calculated that the number of permutations and combinations of brain activity exceeds the number of elementary particles in the universe.
I don't think I will stop learning about football. There are certain parts we will never understand, like what happens in the brain of a player or makes a team fear.
We're told that when we remember, the same parts of our brain light up as when we experienced the event we're remembering. Your brain lives through it again.
There have been studies done on people who meditate and they have found that they actually have increased grey matter in certain parts of their brain and more neural conductivity, meaning more connections between certain parts of the brain. They have increased capacity for, in some cases, memory, or reasoning.
I think I've been fortunate enough to have a fairly long career and hopefully I'm at the middle of it now. And I think I'm starting to develop a certain amount of experience and a certain amount of wisdom about kind of what really matters and what doesn't matter.
Once again you are wrong sir, darkness does not exist either. Darkness is in reality the absence of light. Light we can study, but not darkness. In fact we can use Newton's prism to break white light into many colors and study the various wavelengths of each color. You cannot measure darkness. A simple ray of light can break into a world of darkness and illuminate it. How can you know how dark a certain space is? You measure the amount of light present. Isn't this correct? Darkness is a term used by man to describe what happens when there is no light present.
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.
Most brain scientists have not taught 4th grade, and don't know very much about the classroom, even though they might study learning in some detail. Most education professionals, who often know a tremendous amount about the classroom, don't know much about the brain. That is one of the reasons why I am so skeptical about applying brain findings to the classroom.
Through my life and my experience, I believe getting "positive mental attitude" is true. Your brain has certain pathways in it, and if you feed those pathways with certain types of thoughts, the blood goes to those neurons and nourishes them, and they grow and develop. That's how you build habits. Physically, I think that's how your brain works. If you have certain habits that are negative and causing you problems that you want to change them, you can actually change the blood flow and stuff in your brain by thinking a different way.
Middle class was defined by having certain values and only a certain amount of money. But this new middle class seems to have absolutely no values and an unlimited amount of money.
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.
