Not so sure about this but, your brains made up of lots of cells called neurons.
Neurons signal to each other using electric pulses. These cells also receive electrical signals from the rest of your body telling them what’s going on.
They co-ordinate responses such as muscle movement or hormone release.

Magic!
No not really, your brain is made up of loads of cells called neurons which are able to generate a very tiny electrical impulse. These impulses are what enable your brain to send messages to other parts of your body such as making your legs move when you want to walk or telling your body that it’s too cold.
We are still learning a lot about the brain and we don’t really understand exactly how everything works, such as how memories are made and what memories actually are…

People don’t fully understand how brains work. The brain, and the rest of the nervous system, is made of nerve cells with can transmit information using electrical pulses. These are received from various places (your nose for example) and sent to places (for example move your finger).
Although we do some things about how these work, we don’t really have much information about how the brain stores information/memories or how you think about ideas. Lots of researchers are working on that at the moment.

Your brain is made up of billions of neurons that can send tiny electrical and chemical signals to each other and all around the body. The brain uses up around 20% of all the oxygen you breathe and it takes a lot of energy to keep it running. Most of the jobs the brain does without you even knowing – and it subconsciously regulates everything from breathing, to how often you need the toilet, to how much you sweat.
Scientists are a long way from fully understanding the brain but there is lots of cool research going into finding out. Some researchers use neurons from squid to find out about how neurons send signals because these are the biggest neurons in nature (1000x bigger than human neurons) so it is easier to work with them and make measurements from an individual cell. -

excellent answers guys so ill go with an interesting fact… when the brain is removed at post mortem for examination it has to be suspended to be fixed in formaldehyde solution. if the brain is not suspended it will mould to the shape of the container its placed in.
