It's like the water of the stream it never sits still.

I just wanted you to know that.

Roy's brain is trying

In Mesoamerica, there used to be neurosurgery, and there were these neurosurgeons that used to treat patients.

It's a non spiking cell.

It's been around for about 7,000 years.

And the next steps,

You know, Sebastian, you should just give up.

I am more than my genes. Likewise, every connectome changes over time.

Yellow strengthens the nerves and the brain.

Those beautiful golden drops are the neurotransmitters.

That is precisely what we do today.

And here it is

You are the brain and central nervous system of the ship.

The central nervous system is... your brain and your spinal cord.

Seaweed is a rich source of iodine and selenium.

So, the vagus nerve contacts the gut lining and extents all the way up to the brain stem itself.

So I am indeed a neurosurgeon, and I follow a long tradition of neurosurgery, and what I'm going to tell you about today is adjusting the dials in the circuits in the brain, being able to go anywhere in the brain and turning areas of the brain up or down to help our patients.

That's the red path that's highlighted.

So this particular model is entirely self consistent because it's made itself so.

You touch yourself, there's a stimulus that comes up those very same nerves back up to your brain.

And after 70 hours of intensive singing lessons, he found that the music was able to literally rewire the brains of his patients and create a homologous speech center in their right hemisphere to compensate for the left hemisphere's damage.

And you have Charles Bonnet syndrome.

Memory Game

Nervousness

That's very unnerving.

Idiot!

Phosphine gas.

It's a neurotoxin.

These basepairs sequences regulate the neurotransmitter levels in their brain.

It turns out that cognitive research shows when we are able to do this, it manifests neurologically neural pathways are created in the brain.

Two heads are better than one.

The verdict in both cases cerebral haemorrhage.

We call this the human connectome, and you can think about the connectome sort of as the wiring diagram of the brain.

Do physical exercise.

GLaDOS You know what doesn't rhyme with compliance?

Insecure. Neurotic.

Are you some kind of neurologist?

It has two brains.

This is some of what I learned.

I'm going to describe this application again, as I said, in the last week of this class.

And what I'm talking about are nerves.

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.

One way is by activating the vagus nerve.
