We do not often consider the elegant complexity that brings a thought to action, every waking and non-waking moment of our lives. Study the nerves, brain and spinal cord as they appear on their own and in whole-body plastinates. See the brain of the 'Baseball Player', right after he has powered a hit. See the 'Man at Leisure' with raised arms, exposing the nerves of his upper extremities. Learn how important signals—pain, hunger, fear—are sent via the nervous system, throughout the body.
