Over the past two decades researchers and clinicians in the neurosciences have witnessed a literal information explosion in the area of brain imaging and neuropsychological functioning. Until recently we could not view the nervous system except through the use of invasive procedures. Today, a variety of imaging techniques are available, but this technology has advanced so rapidly that it has been difficult for new information to be consolidated into a single source. The goal of this volume is to present information on technological advances along with current standards and techniques in the area of brain imaging and neuropsychological functioning. The quality of brain imaging techniques has improved dramatically. In 1975 one had to be content with a brain image that only offered a gross distinction between ventricular cavities, brain, and bone tissue. Current imaging techniques offer considerable precision and approximate gross neuroanatomy to such an extent that differentiation between brain nuclei, pathways, and white­ gray matter is possible. These technological advances have progressed so rapidly that basic and clinical research have lagged behind. It is not uncommon, particularly in longitudinal research, for the technical meth­ odology of a study to become obsolete while that study is still in progress. This has hampered certain aspects of systematic research and has also produced the need for a textbook that could address contemporary issues in brain imaging and neuropsychology.

There are arguably few areas of science more fiercely contested than the question of what makes us who we are. Are we products of our environments or our genes? Is nature the governing force behind our behaviour or is it nurture? While it is now widely agreed that it is a mixture of both, discussions continue as to which is the dominant influence. This unique volume presents a clear explanation of heritability, the ongoing nature versus nurture debate and the evidence that is currently available. Starting at the beginning of the modern nature-nurture debate, with Darwin and Galton, this book describes how evolution posed a challenge to humanity by demonstrating that humans are animals, and how modern social science was necessitated when humans became an object of natural science. It clearly sets out the most common misconceptions such as the idea that heritability means that a trait is 'genetic' or that it is a justification for eugenics.
