Book Description
Comprehensive Overview of Advances in OlfactionThe common belief is that human smell perception is much reduced compared with other mammals, so that whatever abilities are uncovered and investigated in animal research would have little significance for humans. However, new evidence from a variety of sources indicates this traditional view is likely

Book Description
Many advances have been made in the last decade in the understanding of the computational principles underlying olfactory system functioning. Neuromorphic Olfaction is a collaboration among European researchers who, through NEUROCHEM (Fp7-Grant Agreement Number 216916)-a challenging and innovative European-funded project-introduce novel computing p

Book Description
The impacts of specifically experienced external and internal environments upon phylogenetically established pathways of ontogenetic development seem to be responsible for the intra-species variation of organisms. Therefore normal function, as well as disorders of sensory systems, can often be better understood by considering the principles of ontogenetic maturation and the time schedule of environmental influences during that period. Sensory organs and systems have long been considered to be hereditally determin ed for their analysis of the environment. However, it is becoming more and more clear that their specificity depends also upon the sequence and nature of environ mental impacts, impacts during highly sensitive periods of postnatal life being most effective. The present book, using an interdisciplinary approach, has brought together various descriptions of developmental processes for one of the phylogenetically oldest sensory analytical circuits, the olfactory system. Although investigations of a wide range of vertebrates are included, from marsupials to man, the main attention was given to rodents, the most frequently used experimental animal in this fields of research. Authors have been asked for reviews and original considerations on the rationales of developmental principles in the olfactory system, and wherever appropriate to highlight its uniqueness or similarities with other parts of the nervous system. Authors were also asked to consider future needs of research in their fields, to describe their own approaches in this context, and to outline general horizons of neurodevelopmental research.

Book Description
Scientists not infrequently succumb to the frustration they feel when they have to garner often quite fundamental information about an undeveloped field from scattered publications covering many disciplines by writing their own review of the field in question. This is an invaluable exercise, particularly for those in the business of stimulating students to grapple with unfamiliar ideas and concepts, since it makes the introduction to that literature much less painful. To some extent I, too, have succumbed to this frustration by writing this book, but I have also, much more importantly, tried to develop out of this literature an olfactory perspective of the whole organism in its environment - in its feeding relations, reproductive biology, ecological isolation, social organization, ability to give warning and defend itself, and ability to navigate when displaced from home. One event more than any other acted as a catalyst to encourage me to start this task. One evening in the arid Australian bush, as I was returning to camp, the stirring of the air bathed me in a host of smells I had been unaware of in the stifling heat of the day. I found their effect on me quite extraordinary, for they refreshed and revitalized me more than I would ever have imagined possible. I had a rare glimpse of what it must be like to be macrosmatic-to rely on one's nose for one's sensory input.

Book Description
The sense of smell has an essential role in locating food, detecting predators, navigating, and communicating social information. Accordingly, the olfactory system has evolved complex repertoires of receptors to face these problems. Although the sense of taste has less far-reaching tasks, they are every bit as essential for the animals well-being, allowing it to reject toxic materials and to select nutritionally valuable food. The last decade has seen a massive advance in understanding the molecular logic of chemosensory information processing, beyond that already achieved in the rst few years following Linda Bucks discovery of odorant receptors. Shortly afterwards, the major principles of olfactory representation had been established in mammals as the one neuron/ one receptor rule and the convergence of neurons, which express the same receptor, onto individual modules in the olfactory bulb. In recent years, such studies have been extended to lower vertebrates, including shes and other phyla, i. e. , arthropods, worms, and insects, showing both the general validity of these concepts and some exceptions to the rule. In parallel, hallmarks of the molecular logic of taste sensation have been deciphered and found to differ in interesting ways from those of smell sensation.

Book Description
Written by leaders in the field of chemosensation, Chemosensory Transduction provides a comprehensive resource for understanding the molecular mechanisms that allow animals to detect their chemical world. The text focuses on mammals, but also includes several chapters on chemosensory transduction mechanisms in lower vertebrates and insects. This book examines transduction mechanisms in the olfactory, taste, and somatosensory (chemesthetic) systems as well as in a variety of internal sensors that are responsible for homeostatic regulation of the body. Chapters cover such topics as social odors in mammals, vertebrate and invertebrate olfactory receptors, peptide signaling in taste and gut nutrient sensing. Includes a foreword by preeminent olfactory scientist Stuart Firestein, Chair of Columbia University’s Department of Biological Sciences in New York, NY. Chemosensory Transduction describes state-of-the-art approaches and key findings related to the study of the chemical senses. Thus, it serves as the go-to reference for this subject for practicing scientists and students with backgrounds in sensory biology and/or neurobiology. The volume will also be valuable for industry researchers engaged in the design or testing of flavors, fragrances, foods and/or pharmaceuticals. Provides a comprehensive overview for all chemosensory transduction mechanisms Valuable for academics focused on sensory biology, neurobiology, and chemosensory transduction, as well as industry researchers in new flavor, fragrance, and food testing Edited by leading experts in the field of olfactory transduction Focuses on mammals, but lower vertebrates and invertebrate model systems are also included

Book Description
Intraspecific communication involves the activation of chemoreceptors and subsequent activation of different central areas that coordinate the responses of the entire organism—ranging from behavioral modification to modulation of hormones release. Animals emit intraspecific chemical signals, often referred to as pheromones, to advertise their presence to members of the same species and to regulate interactions aimed at establishing and regulating social and reproductive bonds. In the last two decades, scientists have developed a greater understanding of the neural processing of these chemical signals. Neurobiology of Chemical Communication explores the role of the chemical senses in mediating intraspecific communication. Providing an up-to-date outline of the most recent advances in the field, it presents data from laboratory and wild species, ranging from invertebrates to vertebrates, from insects to humans. The book examines the structure, anatomy, electrophysiology, and molecular biology of pheromones. It discusses how chemical signals work on different mammalian and non-mammalian species and includes chapters on insects, Drosophila, honey bees, amphibians, mice, tigers, and cattle. It also explores the controversial topic of human pheromones. An essential reference for students and researchers in the field of pheromones, this is also an ideal resource for those working on behavioral phenotyping of animal models and persons interested in the biology/ecology of wild and domestic species.
