This book takes a comparative and integrative approach to lateralization in a wide range of vertebrate species, including humans, and highlights model systems that have proved invaluable in elucidating the function, causes, development, and evolution of lateralization. The volume is arranged in four parts, beginning with the evolution of lateralization, moving to its development, cognitive dimensions, and finally its role in memory. Experts in lateralization in lower vertebrates, birds, nonprimate mammals, and primates have contributed chapters in which they discuss their own research and consider its implications to humans.
