It is a great honor and pleasure for me to introduce this book; an honor, because of the scientific renown and authority of the investigators who have edited the volume and contributed the chapters; a pleasure, because my own long-lasting interest in the baroreflexes has always gone in the same directions as those along which the authors of this book have conceived and organized their work.
