It seemed right that an image of brain cells was on the spine of the book. After all, science is the product of human brainpower down the ages, and here are some of the most erudite of those scientific minds.
Several of the scientists in the book, too, have written about the brain. Professor of Neuroimaging Gina Rippon, for example, talks about its plasticity, and how running repairs might be made to the brain itself, and consultant neurologist Professor Adrian Williams has written a radical response to the question What are you optimistic about, one that dares to raise the prospect of immortality.
Others, for example David Burden and Kathleen Maitland, take us into a world where the interface between humans and computers has evolved to the point where current distinctions between our perceptions of reality and virtual worlds are difficult to sustain.
