The brain is the center of the human nervous system and is highly complex organ. The human brain is located in the head, protected by the skull and close to the primary sensory apparatus of vision, hearing, balance, taste and smell. Brains control behavior either by activating muscles, or by causing secretion of chemicals such as hormones.
The human brain weighs between 3 to 3.5 pounds.
You brain is about 2% your total body weight but uses 20% of your body's energy. 4-6 minutes your brain can survive without oxygen before it stars to die.
