It is rare that an individual with highly specialised knowledge can communicate it to a general audience. If Susan Greenfield is a ubiquitous media figure it's because not only does she talk about the brain so clearly but she also passes on some of the excitement of working with scientific ideas. Susan talks about the brain the way other people talk about fine art or football. It is a thing of endless beauty and fascination.
This page is a short profile of Baroness Susan Greenfield, a neurobiologist and media personality in the U.K. Although those interested in Greenfield may find this article interesting, the site is most useful as a part of a series of profiles on women in science. There are also links to various other history of science resources as well. The site's main liability is that the pages are large and can be very slow opening.
