Look around you.
Just look around you.
Have you worked out what we're looking for?
Correct.
The answer is...
This programme, "The Brain", is sadly the last in the series,
and can be found at the very end of your textbook.
Please ensure you have your copybook at hand,
as you'll be asked to take down notes from the screen
at various points throughout the programme.
What is the brain?
If you don' t know that, you've forgotten how to think.
You see, the brain is many things.
It's a calculator, a dictionary, a battery,
a camera, a TV and radio.
In fact, it's all of these things and more.
Pretty smart for something that resembles a garden cauliflower.
The brain is basically a wrinkled bag of skin
filled with warm water, veins and thought muscles.
Think of it as a kind of modified heart, only with a mind or brain.
It sits atop the body issuing its orders to the various components,
controlling our walking and jumping,
eye-to-eye coordination.
Regulating our size.
In fact, pretty much everything we do is governed by its decisions.
It's a right old bossyboots!
The opposite of the brain is probably the bum.
It's nowhere near as intelligent as the brain.
It doesn' t have to be,
as it only needs to make very basic calculations.
An experiment was carried out
to illustrate the effects of brainial stimulation.
For this experiment,
we're going to use a small area of our subject's brain
known as the broab.
Using a hand drill,
a small hole is formed at the base of Nigel's skull.
You don' t have to be a brain surgeon operate on the brain,
but you will need some training.
After all, you'd hardly call out a hairdresser to fix a carburettor.
Now a thin probe is slowly inserted into our hole
so that the probe probes the broab.
Observe the reaction and note the results down in your copybook.
At first, Nigel appears to experience some discomfort.
But this soon gives way to a feeling of elation.
And as we force the probe deeper, it induces this reaction.
A feeling of wanting to sneeze but being completely unable to.
If you're trying this experiment for yourself,
be aware that the effect is often permanent.
Write that down in your copybook now.
These days most of us know someone who's had an EBE,
an electronic brain enhancement.
People get it done for a variety of reasons.
For example, if you want to read faster.
Or to think up funnier jokes in social situations.
She seems to like it.
Tempting, isn' t it?
But just take a look at this young man.
Don' t be a fool.
It's not just humans or animals that have a brain.
Almost every living being has one.
If we look inside one of these peas, we can see its tiny brain.
Look at the little ridges,
down which the pea sends electrical impulses to other peas,
determining its daily duties and its status in the pod.
Let's pop it back inside now, and leave the pea be.
An experiment was carried out
to illustrate the brain's powers of perception.
First, a human brain is lowered gently into a solution of brine.
Next, we connect a 9-volt battery,
so an electrical current flows through the brine into the brain.
Finally, a telephone line is installed...
..and the experiment can begin.
We're going to set the brain a simple problem,
so have your pen and paper ready.
Brain, how many nuts are there in this jar?
The brain sets to work until reaches its answer.
(PHONE RINGS)
Hello?
It's the brain.
Can I have your answer, please?
OK.
Hi.
Thank you. Goodbye.
Here's the brain's estimation.
54.
Let's see if the brain is right.
Exactly...
54 nuts.
Well done.
As a reward, the brain is fed.
What a clever little brain.
We hope you enjoyed this series as much we enjoyed making it.
And so, we raise a glass to you, the viewer.
There's no need to open the champagne now.
Perhaps we'll save it for the next series.
Until then, take care of yourself.
And remember, look around you.
