We've long known that the brain is an amazing thing, but did you specifically know that:
• Every person has more than 75km of nerves in their body.
• Your nerves can send messages faster than a Grand Prix car travels.
• The brain is the most complex machine
in the universe - it has over 100,000,000, 000 nerve cells each with
up to 150,000 connections. Each cell is connected to 25,000 others.
• If every person on the planet simultaneously made 200,000 phone calls, there would be the same total number of connections as in a single human brain in a day
• The grey cells occupy only 5% of our brains - 95% is taken up by the communication network that runs between the grey cells!
• The brain weighs about 1.5 kg in an adult human, about 1.5% of the body weight.
•
Damaged brain cells do not regenerate but mental and physical
functions can improve after mild or moderate brain damage with skilful
rehabilitation.
• Compared to other animals, human brains are big for the body.
• The human brain is only just bigger than your two fists.
• On average, the male brain (approx 1.4kg) is slightly bigger than the female brain (approx 1.26kg).
• Each half of the brain controls the other half of your body.
• In right-handed individuals
(which comprise 91% of people): the right side of the brain controls:
musical talent, fantasy, imagination, dreams, drawing, and painting. The left
side of the brain controls: mathematical ability, ability to solve
logic problems, controls language skills, remembers names, dates, and
facts.
•
The grey part of the brain is folded to fit inside the skull and, if
flattened, it would cover the surface of an office desk.
• The brain contains 100 billion brain cells of which, 100,000 are irretrievably lost each day.
• You can retain about seven facts at any one time in short term memory, but over the long termyour brain has to forget things to make room for new memories.
