Human Brain: An Amazing Real Machine Brain is one the most important parts of human body. In fact, brain is the most complex organ found in human body. Through motor neurons it controls all the important functions and actions that our body performs 24 hours a day. This is why brain is called the Central Processing Unit (CPU) of human body. Like a computer can't perform any task without CPU , so does our body can't perform any action without brain.  Human brain is an amazing organ that works quite differently as compared to brains of other species. Our brain has exceptional capabilities of abstract reasoning, logic and language detection. To know more about these amazing capabilities which our brain possesses, let us read the following given facts. Structure and Anatomy of Human Brain  1. Weight and Size: The average adult human brain weighs about 1.4 kilograms (3 pounds) and makes up about 2% of the body's weight. Brain of the Blue Whales weighs about 7 kg. Whereas, an ele...
