This is an introductory text to the development of the nervous system with particular emphasis on the relationship between development and behaviour. The first chapters focus on the development of the nervous system, the second part of the book considers the output of the developing nervous system -behaviour-, examining the role of factors present during development which influence the growth of the nervous system and subsequent behaviour. The subject matter is extensively illustrated in clear, two-colour diagrams, and each chapter ends with a list of learning objectives and questions.
