There's a new wave of female neuroscientists that are finding important differences between female and male brains in
neuron
connectivity, in brain structure, in brain activity.
They send little pulses of electricity down their processes to each other, and where they contact each other, those little pulses of electricity can jump from one
neuron
to the other.
The motor
neuron
and the muscle cell are separated by a tiny gap, and the exchange of particles across this gap enables the contraction.
On one side of the gap, the motor
neuron
contains a neurotransmitter called acetylcholine.
In response to a signal from the brain, the motor
neuron
releases acetylcholine, which triggers pores on the muscle cell membrane to open.
And only then, after all this
neuron
heavy lifting, do we consciously experience this cup of coffee.
In Parkinson's, there's one particular kind of
neuron
deep in your brain that is responsible for the disease, and these technologies just don't have the resolution that you need to get at that.
That's how the mirror
neuron
system works.
But it's a bit more than cataloging because you actually have to describe and discover all the rules of communication, the rules of connectivity, because the neurons don't just like to connect with any
neuron.
Every
neuron
is different.
So there is no
neuron
in my brain that is the same as another, and there is no
neuron
in my brain that is the same as in yours.
And in fact you need one laptop to do all the calculations just for one
neuron.
And each
neuron
makes something like 1,000 to 10,000 contacts with other neurons in the brain.
For example, if I do that, and reach and grab an apple, a motor command
neuron
in the front of my brain will fire.
If I reach out and pull an object, another
neuron
will fire, commanding me to pull that object.
So, here is a
neuron
that fires when I reach and grab something, but it also fires when I watch Joe reaching and grabbing something.
Because it's as though this
neuron
is adopting the other person's point of view.
And I claim that what happened was the sudden emergence of a sophisticated mirror
neuron
system, which allowed you to emulate and imitate other people's actions.
Now there is another kind of mirror neuron, which is involved in something quite different.
In other words, if somebody touches me, my hand,
neuron
in the somatosensory cortex in the sensory region of the brain fires.
But the same neuron, in some cases, will fire when I simply watch another person being touched.
Okay, so there is a feedback signal that vetoes the signal of the mirror
neuron
preventing you from consciously experiencing that touch.
Now the astonishing thing is, if you have pain in your phantom limb, you squeeze the other person's hand, massage the other person's hand, that relieves the pain in your phantom hand, almost as though the
neuron
were obtaining relief from merely watching somebody else being massaged.
So, I'm saying the mirror
neuron
system underlies the interface allowing you to rethink about issues like consciousness, representation of self, what separates you from other human beings, what allows you to empathize with other human beings, and also even things like the emergence of culture and civilization, which is unique to human beings.
And so, when you start to look at emergent systems, you can look at a
neuron
under a microscope.
A
neuron
under the microscope is very elegant with little things sticking out and little things over here, but when you start to put them together in a complex system, and you start to see that it becomes a brain, and that brain can create intelligence, what we're talking about in the body, and cancer is starting to model it like a complex system.
I edited out the last bit when I asked, "Where is the neuron?" and she says, "The
neuron?
The neuron," and then she looked and did this.
In this diagram, every node is a neuron, and every line is a connection.
But this is just a single
neuron.
