The big brain

Brain and body
Your amazing Brain keeps your body on track all the time. It
monitors your heart rate, checks your blood flow and keeps
your breathing just right. It does all this and more without
you even having to think about it. In the Brain and body
section you can measure your pulse, take your blood oxygen
level and see if by squeezing a pump you can keep up with your
hearts action. You can also try to do the job of the brain in
the game Staying alive. Try and see how well you can
keep the runner’s pulse, breathing, and sweating levels
constant.
Brain Matters
The brain accounts for only 2% of your body weight but uses
more than 20% of your body’s oxygen. It looks like a giant
walnut and is about the size of a melon. In Brain Matters
you can take a look at animal models in Beasty brains.
Or you could discover the models of human brains at different
ages for you to weigh and compare. Can you find out what
weight an adult brain is?

Gregory’s Games
Your brain uses hundreds of
tricks and shortcuts to make sense of what you see. Life is full of
illusions. Your brain ‘fills in’ missing information and makes
‘best guesses’. When you sit in a train at a station and the train
alongside begins to slide past, which train is actually moving?
Scientists use illusions to understand how your brain makes sense of
the world. In Gregory’s games you can tease your brain with mind
bending illusions at the same time as learning how your brain deals
with them. If you like illusions you might also like to try some of
our online Optical
Illusions.
Super senses
Each of your eyes contains about one hundred million
light-sensitive cells and about three million cone cells that
are sensitive to colour. In Super senses you can
discover the secrets to your senses, peer through a huge eye
and find out why some people are colour blind, see inside
your ear and test how powerful your sense of smell is. If you
are brave enough you might want to mix your senses and see how
easy it is to trick them in Mixing the senses.

Love and sex
A sperm swimming to an egg is like a person trying to swim across
an English Channel full of treacle. Of 200 million sperm that
start the journey, only a couple of hundred will complete it and
only one will fertilise the egg. In Love and sex you can find
out what It feels like to be pregnant, feel a baby move in its
mothers tummy, go back inside the womb and take a voyage of
discovery to start a new life in the amazing Sperm Journey. |
