The study of areas in the cerebral cortex has a long history, bringing empirical data into close relation with fundamental conceptual issues about the cortex. The subject is currently being revitalized with the advent of new experimental methods and this book brings a modern perspective to the study of these areas. Cortical Areas: Unity and Diversity explores the correspondence of different methods of mapping areas, the correlation between connectivity and areas, interspecies variations and the developmental origin of areal differences. Cortical areas are also discussed in relation to functional evidence, discussing for instance similarities in cybernetic function between different sensory areas. The book also considers morphological substrates for integration between areas before exploring fundamental questions often asked in neurobiology and brain theory.
