Based on the observations of some of the story is known that the human brain can remain active for several seconds after the head cut. But doctors believe that it is a reflection of muscle twitch.
Dr Harold Hillman, former director of the Unity Laboratory of Applied Neural Biology at the University of Surrey said that the death occurred because of the separation between the brain with the spinal cord, but it is painful that many countries do not impose this method.
2. The brain can learn the message of the unconscious.
The brain can learn the message that comes from the unconscious person so that will affect the behavior of the person. Many companies use this as a promotional event to influence someone to buy their products.

But the weight of the brain is compared with his size, so that the human brain remains to be the greatest. In addition, intelligence is also associated with various components in the brain, and mammals have the largest cerebral cortex responsible for memory function, communication and thinking.
