I Wonder How The Brain Works?

For quite a while, I've wondered how the brain worked and whats inside. For starters, how many cells are in the brain? How many cells are used to control our bodies?

Well, the answer is 100 BILLION CELLS. There are 100 billion cells inside of an average adult brain, 100 billion freaking cells! Unbelievable. Every cell is connected by synapses, every cell can connect to tens of thousands of brain cells. To explain it a bit easier, think of yourself as a brain cell, you have a long rope connected to ten thousand other people, and then those people have a rope connected to another ten thousand people and it goes on and on until every person in the world is connected and more. Imagine that! Another word for a nerve cell is a neuron. The image below is a picture of a neuron.

Another thing I learned was that a skin cell lives for about two to three weeks, a Colon cell lives for about four days, but brain cells live for an entire lifetime. Also, if one of the cells in your brain die, they aren't replaced.

I also learned that if your heart stops, the brain survives for about six minutes after. If you go without CPR for six minutes you can't be brought back to life. Cardiopulmonary resuscitation (CPR) needs to be started before the six minutes are up to bring the human back and the brain usually survives the lack of oxygen. But after the six minutes are up the brain begins to die.

Did you know that your brain has the ability to heal itself? People thought after a stroke the brain had very little ability to heal itself. But some people regain function after the stroke and survive, so the brain is definitely a fighter when it's damaged and can heal itself.

I learned a lot about the brain, and there is much much more to discover.
