Do you know .....
the weight of an average human brain is about 1300-1400g - @ 3lbs i.e., almost one bag of sugar.
It's smaller than an elephant's brain (6000g) but bigger than a monkey's brain (95g)! A dog's brain weighs about 72g and a cat's brain weighs abut 30g.
Your skin weighs twice as much as your brain!
...the brain represents about 2% of your total body weight. It is roughly 140mm wide, 167mm long and 93mm high
...neurons multiply at a rate 250,000 neurons per minute during early pregnancy
...your brain consists of 60% white matter and 40% grey matter
...information travels at different speeds within different types of neurons. Transmission can be as slow as 0.5 meters/sec or as fast as 120 meters/sec. Traveling at 120 meters/sec is the same as going 268 miles/hour
The human brain is approximately 75% water
...your brain is capable of having more ideas than the number of atoms in the known universe!

...if you could harness the power used by your brain, you could power as a 10-watt light bulb
..."I had brain surgery 10 years ago, so I know some pretty fascinating things about the brain. One of the most fascinating things I learned is that the brain itself is incapable of feeling pain. (That doesn't mean brain surgery doesn't hurt!)"
