Section 5.0. provides more than 80 interactive quiz questions to test your neuroscience knowledge. Section 6.0. introduces the Inking Zone. You can now annotate templates of the nervous system using a stylus, mouse or touch, and then save your annotated diagrams for inclusion in your own neuroscience notes. In Section 7.0., you'll find two video tutorials: one on Alzheimer's disease and another on the HPA axis, which highlight key biological principles. Section 8.0. offers even more resources, such as The Neuroscience Dictionary, to further your knowledge of the human body, as well as a recommended reading list.
