Here are ten remarkable facts about our most complex organ, our brain, according to BBC One’s Inside the Human Body.
– The human brain is so sophisticated it takes nearly 20 years to mature
– In the womb, humans grow 8,000 new brain cells every second
-By the time humans are born they have all the brain cells they will ever need
-The human brain is the “most sophisticated thing” in the known universe
-New-born babies can recognise their mother’s face after just a few hours
-Babies can see in the womb but only in black and white. However their eyes are sensitive enough to detect the dim light passing through their mother’s belly
-Humans blink up to 20 times every minute. Each blink lasts around half a second. But add them together, and humans are living in the dark for more than an hour every day
-Each brain cell will make, on average, 10,000 connections with other brain cells
-Learning to balance and co-ordinate your body is so complex the area of the brain devoted to this task contains as many cells as the rest of the brain put together
-Young divers in Thailand have taught their eyes to focus underwater by making their irises contract rather than dilate. All children can develop this skill if they start at a young enough age
