ABSTRACT
Every thought you've ever had, every movement you've ever made, and every emotion you've ever felt were brought to you by that amazing mass that sits within your skull. If you could examine your own brain, you would, no doubt, be surprised to find that it looks like a giant (approximately 3-pound) mushy walnut with the consistency of a soft-boiled egg. The brain and the spinal cord that it sits on top of make up the central nervous system.
