| A Human brain |
Number of minutes your brain can survive without oxygen before it starts to die : 4 to 6
Number of seconds you have before losing consciousness due to blood loss : 8 to 10
Number of watts of power your grain generates when you’re awake : 10 to 23
Percentages of oxygen and blood flow going to the brain : 20
The number of miles of blood vessels in your brain : 100,000
The number of synapses for each neuron in your brain : 1,000 to 10,000
Number of neurons in your brain : 100 billion.
★ Brain just looks like a pile of fat spaghetti, but your brain is actually the most amazing things in the Universe.
★ There are more connections in your brain than there are atoms in the Universe.
★ Everyone has their own unique pattern of wrinkles on their cerebral cortex.
★ If you're a woman your brain weighs 2.5 percent of your body weight, on average, while if you're a man it weighs 2 per cent—but men's brains are heavier on average because men are bigger than women.
★ Brain surgeons can operate on a brain while the person is conscious, as the brain does not feel any pain when it is cut.
★ Your brain has about 100,000,000,000 (100 billion) neurons.
★ Each neuron is connected to about 25,000 other neurons.
★ Nerves or neurons carry messages around your body using electricity.
★ If you stung all your nerves end to end, they would measure 75 kilometres.
★ Nerves can carry signals at a speed of 100 metres a second.
★ When you were in the womb, you grew 250,000 nerves every second.
★ After, you're born, very few nerves are made. By the time you're 10, half of them have died off. But don't worry, you've still got plenty left.
★ Your brain knows when you tickle yourself, which is why you don’t bend over laughing.
★ When you sleep, you’re virtually paralyzed because your brain creates a hormone to prevent you from acting out your dreams.
★ It’s not true that humans only use 10% of their brains; each part of the brain has a purpose.
