One of the major goals of side bias is to understand the relationship between the functioning of the brain and a persons behaviour. Often at times it becomes difficult or unethical to directly study the nervous system during a behaviour and therefore indirect methods are used instead. This book has many facets, many explanations, many techniques and many unanswered questions and scope for future research. This book intends to address each of these issues so that a comprehensive reading of the subject matter is made available to academicians, researchers, and other interested in this issue.
