It is not difficult to find neuroimaging sites on the ever burgeoning world wide web. Unfortunately, many of the sites are very limited in their scope, or are simply so poorly designed that one's interest rapidly wanes. The Harvard Whole Brain Atlas is a rarity; a comprehensive and well designed site that fulfils its objectives. The site contains a huge compilation of modern cross sectional imaging, including CT, MRI, and SPECT in health and disease. There are sections where you can revise normal anatomy, test yourself on the top 100 brain structures, or review the imaging appearances of a number of more common neurological conditions. You might choose to go on a virtual tour of the changes in imaging appearances of acute cerebral infarction over time, for example. There are no advertisements, and no excessive animation or unnecessary frills.

The perfect educational website? Not quite. The user interface is not entirely intuitive (help is provided to get you started though). The anatomy test is a little awkward to use, the temporal “movies” run rather too quickly to be best appreciated, and there are one or two other minor design quirks and broken links—but overall, this is a very well put together site, with a huge amount of imaging data available to the viewer. It is certainly one of the most accomplished neuroimaging sites currently available. Beware of accessing it via a modem though; with so many images, a fast internet connection is a necessity to avoid frustration.
