This volume provides a comprehensive review of recent developments in the fields of vertebrate and invertebrate endocrinology and neurobiology. The classical fields of comparative endocrinology and neurobiology are gaining new momentum from the many projects involving the sequencing of animal genomes. The comparative approach has proven to be one of the most rewarding for the study of gene functions and is a key component of functional genomics. The interactions between comparative endocrinology and genome sequencing as well as developmental biology and neurobiology are providing many exciting discoveries.
