Eric H. Chudler, Research Assistant Professor in the Department of Anesthesiology at the University of Washington, provides this online neurology site aimed at K-12 students and teachers. The Explore the Nervous System section highlights this site, a 60 part tutorial on the brain, spinal cord, nervous system, neurons, sensory systems, neurosystems, neuroscience methods, and the effects of drugs on the nervous system. Marked by clear, concise language and colorful illustrations, these tutorials offer a set of activities in thirteen categories, including nervous system modeling, brain games, sleep and dreaming, and biological rhythms. A series of annotated pointers to other related Internet resources and a bibliography of both online and print sources round out this information-rich site.
