What is it that makes you distinct from me? Identity is a term much used
but hard to define. For that very reason, it has long been a topic of
fascination for philosophers but has been regarded with aversion by
neuroscientists--until now. Susan Greenfield takes us on a journey in
search of a biological interpretation of this most elusive of concepts,
guiding us through the social and psychiatric perspectives and
ultimately to the heart of the physical brain. Greenfield argues that as
the brain adapts exquisitely to environment, the cultural challenges of
the twenty-first century with its screen-based technologies mean that we
are facing unprecedented changes to identity itself.
