Your brain is 75% water. A dehydration of 2% can affect your brain.
Your brain has a weight of 1300 – 1400 g of which 60% is fat, making the brain the fattest organ. 25% of your cholesterol is in your brain. Without enough cholesterol your brain cells may suffer.
Your brain has 86 billion nervous cells, and each may have up to 40.000 synapses. A piece of brain as big as a sand particle has one billion synapses.
Your brain reaches maturity at the age of 25.
Electricity
Brain cells use electricity to communicate and function. The entire brain generates 12-15 watts of power, enough to power a LED. Your brain is generating 50.000 thoughts a day.
When you sleep your brain is not resting.
In the last 200 years the IQ of humans has decreased by 1,6 points per decade in the last 200 years. Brain size in humans has decreased in the last 10,000 years by a tennis ball volume. Egyptian Mummies had larger brains than us and so did Neanderthals.
Multitasking is reducing brain ability to function, decreases attention span, ability to learn and short-term memory.

Your brain has a tofu consistency. Its surface called cortex is folded to increase its surface and if unfolded is as big as a pillow cover.
In patients with dementia the cortex surface is less, the smarter you are the more folded your cortex is.
Your brain has 200 trillion connections among cells which is 1000 times more than the stars in Milky Way galaxy.

Brain is using 1/5 of your oxygen . Your brain looks like a pecan, and one need to eat pecans for brain functioning.
A man from United States has cut the head of his chicken and the chicken survived for 18 months without a brain and was named Mike.
The average brain size of Egyptian mummies was 1350 centimeters and now is just 1200 cc in modern humans.
Albert Einstein brain was smaller than the average.
You may need 2700 years to count all your neurons. An elephant has 5,59 billion nervous cells in his brain, but the human has 16.3 billion nervous cells in his brain.
