This Web site is the online companion to a five-part series about the human brain from PBS. With loads of fantastic interactive features, this site makes learning about the brain both fun. One of the highlight of this site is the 3-D tour of the brain; users can rotate and zoom in or out on a model of the brain, clicking on areas of interest to learn their function. The drop-down menus on the same page allow users to quickly explore the brain by function or area. Other features of this Web site include timeline for the history of the brain; a segment that demystifies brain-scanning techniques; and a set of mind illusions, including a rather freaky one involving Abraham Lincoln. Visitors may also access overviews and video clips from each of the five episodes in the television series, which cover the baby, child, teenage, adult, and aging brain. A fascinating subject and an excellent Web site for any audience.
