Human Brain
Every organism, no matter whether it is an earthworm, a snail, a fish or a human being, takes in information from the environment through differently structured sensory organs. This was absorbed first by a diffusely organised nervous system, which, in the course of evolution, has been replaced by a hierarchically organised one. Eventually a controlling centre has developed that interconnects and coordinates the nerve impulses supplied by receptors, reacts appropriately and is called the brain. In more highly developed organisms a part of the body has developed into a head, in parallel to the development of the brain.
