So
neurons
are the information processing apparatus that those communities of cells built up.
And like the rest of the brain, it's made of
neurons.
So the human brain has about a hundred billion
neurons
in it.
And the
neurons
communicate with each other by sending little pulses or spikes of electricity via connections to each other.
And scientists have begun to understand how spatial memory works by recording from individual
neurons
in rats or mice while they forage or explore an environment looking for food.
And if we record from lots of different neurons, we'll see that different
neurons
fire when the animal goes in different parts of its environment, like in this square box shown here.
So this is just one example of a new era really in cognitive neuroscience where we're beginning to understand psychological processes like how you remember or imagine or even think in terms of the actions of the billions of individual
neurons
that make up our brains.
Your brain is made out of 100 billion cells, called
neurons.
And these
neurons
communicate with each other with electricity.
Out comes the liposuction fluid, and in this case, the stem cells are isolated and turned into
neurons.
And very quickly Cajal realized that
neurons
don't operate alone, but rather make connections with others that form circuits just like in a computer.
Today, a century later, when researchers want to visualize neurons, they light them up from the inside rather than darkening them.
And it's so called, of course, because all of these
neurons
are glowing different colors.
Now sometimes neuroscientists need to identify individual molecular components of neurons, molecules, rather than the entire cell.
He turned them into the IPS cells that I've just told you about, and then he turned those IPS cells into the motor
neurons
that actually were dying in the disease.
And as he watched the disease unfold, he was able to discover that actually the motor
neurons
were dying in the disease in a different way than the field had previously thought.
There was another kind of cell that actually was sending out a toxin and contributing to the death of these motor neurons, and you simply couldn't see it until you had the human model.
But what you can do with human stem cells, now, is actually create avatars, and you can create the cells, whether it's the live motor
neurons
or the beating cardiac cells or liver cells or other kinds of cells, and you can test for drugs, promising compounds, on the actual cells that you're trying to affect, and this is now, and it's absolutely extraordinary, and you're going to know at the beginning, the very early stages of doing your assay development and your testing, you're not going to have to wait 13 years until you've brought a drug to market, only to find out that actually it doesn't work, or even worse, harms people.
I won't go through the details of it, but that's an important discovery, and we know a good bit about that now, and it's just a small piece of it, but it's important because those are the
neurons
that you would lose if you had Parkinson's disease, and they're also the
neurons
that are hijacked by literally every drug of abuse, and that makes sense.
These
neurons
are also involved in the way you can assign value to literally abstract ideas, and I put some symbols up here that we assign value to for various reasons.
You know that when you have those abusive voices, all those little
neurons
get together and in that little gap you get a real toxic "I want to kill myself" kind of chemical, and if you have that over and over again on a loop tape, you might have yourself depression.
So actually, it's filled with 100 billion
neurons
just zizzing away, electrically transmitting information, zizzing, zizzing.
He generated
neurons
from these induced pluripotent stem cells from patients who have Lou Gehrig's Disease, and he differentiated them into neurons, and what's amazing is that these
neurons
also show symptoms of the disease.
And here we are, out of billions of neurons, just recording, 10 years ago, a hundred.
Everything that we ever do, everything that every human has ever done, do or will do, requires the toil of populations of
neurons
producing these kinds of storms.
So when we look at the brains of these animals, on the top panel you see the alignment of 125 cells showing what happens with the brain activity, the electrical storms, of this sample of
neurons
in the brain when the animal is using a joystick.
But all of this sensory information has to be processed by a brain, and yes, indeed, flies have a brain, a brain of about 100,000
neurons.
But remember that this kind of brain, which is much, much smaller — instead of 100 billion neurons, it has 100,000
neurons
— but this is the most common form of brain on the planet and has been for 400 million years.
Well, it's simple in the sense that it has fewer neurons, but is that a fair metric?
So I propose we have a Trump number, and the Trump number is the ratio of this man's behavioral repertoire to the number of
neurons
in his brain.
