This video provides a quick introduction to the central nervous system, the ancestral structures of the brain, the limbic system, and new structures of the brain. As with the previous CrashCourse videos, although you may wish to take notes to capture the key points and distinctions made, you should treat this video as a "trailer" for the proper introduction that will follow in the readings and activities to come.
