We cannot replicate or hope to understand all of the connections coming out of the brain into the rest of the body. Longerish: The brain is made up of millions, if not billions, of neurons. Each of these neurons serves some purpose in some aspect of our physical and mental lives. The main connection between the brain and the rest of the body is the central nervous system.
