This beautiful volume is an appropriate tribute to Prof. Trygg Engen's outstanding contributions to understanding the chemical senses. It summarizes and extends Engen's analysis of olfactory perception and memory. In doing so the volume points the way to the needed synthesis of molecular, neurophysiological, evolutionary and psychophysical methods that would help realize his goals for the field.

In the preface of Odor Sensation and Memory, Trygg Engen wrote in 1991: “The present approach is mainly top-down and psychological”. The book written by his students and friends to honor his memory might express the same claim. Following the triumphant success of the molecular approach and other bottom-up-oriented investigations on olfaction, the sections on perception, learning and memory, hedonic perception and development, with the richly documented analysis of the origins of olfactory preferences, all these themes evoke a faint feeling of nostalgia that fits perfectly well with the filial aim of the book.
