---------------------------
The human brains consists of more than 100 billion neurons (nerve cells) through which the brain's commands are sent in the form of electric pulses. These pulses travel at more than 400 km/h (250 mph), creating enough electricity to power a lightbulb. The brain consumes more energy than any other organ, burning up a whopping one-fifth of the food we take in.
It is estimated that the mental capacity of a 100-year old human with perfect memory could be represented by computer with 10 to the power of 15 bits (one petabit). At the current rate of computer chip development, that figure can be reached in about 35 years. However, that represents just memory capacity, not the extremely complex processes of thought creation and emotions.
But consider this: for all the complexity of the brain, you still have only one thought at a time. Make it a positive thought.

One-quarter of the brains in used to control the eye. We actually see with our brains, with the eyes basically being cameras.
