In Conclusion, all of your brain is at work constantly and is very important to us as an entire species. Our brain has evolved a whole lot over the existence of our race. The Brain is a complex machine that is working full power from before you were born until the very millisecond when your heart stops beating and you die. The brain will always boggle the minds of most scientists for a long time, and maybe that just shows how brilliant everyone is on our little planet.
The Brain has around 10,000,000,000 nerves, that's 10 BILLION! Surprisingly, absolutely none of them can fell pain, or touch for that manner. This was very surprising to me.
