Asymmetry
of the brain and behavior (lateralization) has traditionally been considered
unique to humans. However, research has shown that this phenomenon is
widespread throughout the vertebrate kingdom and found even in some
invertebrate species. A similar basic plan of organization exists across
vertebrates. Summarizing the evidence and highlighting research from the last
twenty years, the authors discuss lateralization from four perspectives –
function, evolution, development and causation – covering a wide range of
animals, including humans. The evolution of lateralization is traced from our
earliest ancestors, through fish and reptiles to birds and mammals. The
benefits of having a divided brain are discussed, as well as the influence of
experience on its development. A final chapter discusses outstanding problems
and areas for further investigation. Experts in this field, the authors present
the latest scientific knowledge clearly and engagingly, making this a valuable
tool for anyone interested in the biology and behavior of brain asymmetries. Draws on neuroscience, behaviour,
psychology and evolution to examine the important and diverse properties of
lateralization Integrates the latest research on
both non-human and human animals, providing a complete perspective on the
subject Authored by three leaders in the
field, who highlight the past twenty years of research.
