Development and Evolution of Brain Size

Development and Evolution of Brain Size: Behavioral Implications contains the proceedings of a symposium entitled ''Development and Evolution of Brain Size: Behavioral Implications,'' held at William Paterson College in Wayne, New Jersey, in April 1978. The papers explore the relationship between evolution and development and its implications for brain size and behavior. This book is comprised of 18 chapters and begins with an overview of the brain-behavior relationship, with emphasis on the importance of brain size for behavior; the effects of genetic selection for brain size on brain substructures and behavior; and whether genetic and environmental manipulations of brain size have similar consequences. The next two chapters explain evolutionary theory and the evolution of the human brain as well as diversity in brain size. A general model for brain evolution that offers some synthetic possibilities for approaching the questions of brain evolution, size, allometry, and reorganization is then described. The correlation between cerebral indices and behavioral differences is also discussed, along with biochemical correlates of selective breeding for brain size. The results of an experiment that assessed the effects of early undernutrition on brain and behavior of developing mice are presented. This monograph should be of interest to students and practitioners in a wide range of disciplines, including evolutionary biology and clinical psychology.
