The human brain is in many ways a fantastic and enigmatic part of the body, and only within the past few decades have scientists begun to understand its many nooks and crannies. When the brain is beset with any number of neurological conditions, it changes in a myriad of ways. This website, provided by the Alzheimer's Association, provides an interactive tour of the brain of a person with Alzheimer's disease. The tour contains sixteen interactive slides, and each slide contains informative text that provides background material. The first seven slides contain a bit of background information about the brain, such as what the brain is composed of and how it functions. Rounding out the site are a selection of links to sites that provide additional information on the brain, such as the Harvard University Whole Brain Atlas site and the BBC's Interactive Brain Map.
