Anyway, as you'll see in a moment,

(Laughter)

Seaweed is a rich source of iodine and selenium.

So here is a nine year old boxer named Milo, who had a very aggressive tumor called a malignant neurofibroma growing on his shoulder.

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

If you hit your thumb with a hammer, these wires in your arm that, of course, we call nerves transmit the information into the junction box in the spinal cord where new wires, new nerves, take the information up to the brain where you become consciously aware that your thumb is now hurt.

Its preference is to travel along the nerve lines.

In the case of multiple sclerosis, the immune system attacks the insulating layers around the nerves in the brain and in the spinal chord.

We have a billion cells in our brains, with ten trillion connections.

They zap the patient with electroshocks, then go through the eye with an ice pick and pull out some nerve fibers.

Once I cut the spinal cord and the sever nerve endings, you won't feel a thing.

You have to put in hundreds of microscopic wires to record from little tiny individual neurons ordinary fibers that put out tiny signals that are microvolts.

It's a thought in my brain, but at the same time, it's busy secreting acetylcholine and doing all sorts of other things as it makes its way from the motor cortex down through the nerve fibers in the arm.

And he took the thing and he looked up to Steve and he said,

Hold the line!

Some of these cables are loose, Harry. I'm surprised you didn't notice a change in the quality of your picture.

Instead of it being the case that that junction box in the spinal cord is just simple where one nerve connects with the next nerve by releasing these little brown packets of chemical information called neurotransmitters in a linear one on one fashion, in fact, what happens is the neurotransmitters spill out in three dimensions

I worked for a very prominent neurologist,

This animal gets rid of them because they take up too much space.

It can physically be there, but is it maybe more about wiring?

It's a neural system that's wired up to reward the brain for doing a grubby clerical job.

You find the same thing in Hinduism.

Wired

You said he was a research pathologist.

For those of you who understand computers, our right hemisphere functions like a parallel processor, while our left hemisphere functions like a serial processor.

Coordinate Grid

It would be just too depressing.

Memory Game

Nervousness

That's very unnerving.

Idiot!

Phosphine gas.

It's a neurotoxin.

Well the body works by starting a motor command in your brain, going down your spinal cord, out the nerves and to your periphery.

So all of those colored lines correspond to bunches of axons, the fibers that join cell bodies to synapses.

Powering up stabilisation gyros 24A through 48C.

This, in essence, is the secret of science.

Pain or paresthesia is a positive test.

It can sense its local environment and actually find resources in the environment to sustain itself.

GLaDOS You know what doesn't rhyme with compliance?

Insecure. Neurotic.

Are you some kind of neurologist?

And what I'm talking about are nerves.

Freedom is the very essence of our democracy.
