We're the neurons in this brain.

We're the neurons in this brain.

The way brains work, I told you all, you have got all these neurons.

We can look at the fabric. And we can change neurons.

Recently they have been discovered in the dorsolateral prefrontal cortex of humans.

Now, the manifestation of this depends on where in the brain these neurons are.

And indeed, you do see it in the human entorhinal cortex, which is the same part of the brain that you see grid cells in rats.

MPP kills primarily dopamine producing neurons in a part of the brain called the pars compacta of the substantia nigra.

And in this slide you see the neurons and the synapses of the brain don't form.

Orexin neurons are found in the hypothalamus but project to many parts of the brain, including several areas that regulate wakefulness.

So together they form a map for the rest of the brain, telling the brain continually, Where am I now within my environment?

Neurons ... communication.

The nasal cavity is unique, as the only place where brain cells (neurons) are directly exposed to the environment.

Now, it turns out there are neurons which are called ordinary motor command neurons in the front of the brain, which have been known for over 50 years.

Now grid cells are found, again, on the inputs to the hippocampus, and they're a bit like place cells.

Those are the neurons of memory.

It's called the basket cell.

Researchers have found that a key part of the human MNS is Broca's region, an area of the brain that, when damaged, prevents the patient from speaking. Broca's region is the human counterpart of the monkey mirror neuron area.

We're looking at neurons here.

(Children speaking) Neurons ... communication.

The neurons were crossing in every which way.

The new neurons replace older ones of the same kind that die a process of natural rejuvenation.

As far as known, only a small fraction of all brain cells fall into the replaceable class when other kinds of neurons die, they are not replaced.

There are these newly identified neurons, mirror neurons, that act like a neuro Wi Fi, activating in our brain exactly the areas activated in theirs.

Because that is what it's creating.

VS Ramachandran The neurons that shaped civilization

When your neurons are replaced, they change.

So, here again you have neurons which are enrolled in empathy.

Without it, these neurons undergo apoptosis.

They're activating mini neurons all in a row.

This isn't what all neurons look like.

Place cells are also being recorded in humans.

Do people have grid cells?

And that is, there are mirror neurons, just as there are mirror neurons for action, there are mirror neurons for touch.

But actually, it's a drive. It comes from the motor of the mind, the wanting part of the mind, the craving part of the mind.

So instead of inserting a wire into one spot of the brain, re engineer the brain itself so that some of its neural elements become responsive to diffusely broadcast signals such as a flash of light.

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.

Mirror neurons Mirror neurons are neurons in the brain that fire when another person is observed doing a certain action.

We can use different neurons with different variations.

And during the encounter these mirror neurons become very alive.

There are neurons there that are sensitive to faces.

How small can neurons get?

Now both of these kinds of cells can make the place cells fire.

There are these newly identified neurons, mirror neurons, that act like a neuro Wi Fi, activating in our brain exactly the areas activated in theirs. We feel with automatically.
