The brain is part of your body’s central nervous system. It’s the most complicated part of your body. The brain is an incredible organ which has the ability to send and receive an enormous amount of information. Scientists have not yet discovered what all parts of the brain do, as it is such a complex structure. However there are many amazing facts about the brain.
There is evidence of brain surgery taking place back in the Stone Age!! Trepanation, the removal of bone from the skull in order to relieve pressure from bleeding, is an ancient surgical technique. Skulls with holes in them from surgery have been found by archaeologists in graves in France.
During mummification the Egyptians would usually remove the brains through the nose.
The human brain carries on growing until we are about 18 years old, and will increase in size by three times in our first year of life.
Neurones can move information at up to 250 mph.
By the time you are 30, your brain is not as good at remembering things, and by the time we are middle aged the brain starts to get smaller.
GCSE biologists, if you need help with understanding the structure of the brain, try our new guide “How to work with the Nervous System: Part 2”. It includes an explanation of what the main parts of the brain do, and how scanners can help us understand the brain. There are questions and answers included.
