The brain is quite flexible and resilient, and this online exhibit from the American Museum of Natural History explores both of these traits, along with looking at current research into how the brain works. This website offers a nice complement to the in situ exhibit, and visitors can make their way through five sections, including "Your Sensing Brain", "Your Emotional Brain", and "Your 21st Century Brain". Each of these sections includes short answers to crucial questions about the brain's functions and activities, such as "Why do memories exist?" In the "Videos" area, found on the right hand side of any page, visitors can check out six different clips that document the creation of the physical exhibit as well as topics that include "Thinking in Symbols". Finally, the site is rounded out by a section of materials for educators that include lesson plans and bulletins with titles like "Inside the Teenage Brain".
