In this interactive model of the brain, users can learn about its parts and specific functions. The model consists of side-by-side image and text areas. Users can employ a variety of control options. For example, they can click on a colorized area of the brain to call up information about it and to alter the position of the three-dimensional brain so that it features the selected part. There are also buttons for rotating the brain and for zooming. In addition, users can select from pop-up menus to learn about a specific brain area such as the corpus callosum and brain functions such as speech. Copyright 2005 Eisenhower National Clearinghouse
