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.

Book Description
The ability of metazoans to sense and interpret the external chemical environment is conferred by the chemosensory nervous system governing the senses of smell and taste. Chemosensory neurons convey external stimuli in the form of electrical impulses, as well as by changes in gene expression. This thesis describes the genetic elucidation of a Caenorhabditis elegans molecular pathway that transduces the presence of pathogens to activate the transcription of a neuroendocrine ligand. Previously, our group has showed that secondary metabolites produced by the pathogen P. aeruginosa cause an expression pattern change of the gene coding for the C. elegans TGF-beta ligand DAF-7. Using forward and reverse genetic approaches, we identified several cGMP-related components that are essential for the pathway, including a subunit for cyclic nucleotide-gated channels, CNG-2, and a cGMP-dependent kinase, EGL-4. We show that while CNG-2 induces daf-7 expression in a calcium-dependent manner, EGL-4 likely works in a calcium-independent manner to regulate daf-7 expression. Our data suggest that EGL-4 acts by selectively promoting the transcription of neuronal genes in response to appropriate stimuli. In a separate set of experiments, we also showed that the expression of daf-7 is discretely regulated by different classes of intraflagellar transport proteins that function in cilia.

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
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
Invertebrates have proven to be extremely useful model systems for gaining insights into the neural and molecular mechanisms of sensory processing, motor control and higher functions such as feeding behavior, learning and memory, navigation, and social behavior. A major factor in their enormous contributions to neuroscience is the relative simplicity of invertebrate nervous systems. In addition, some invertebrates, primarily the molluscs, have large cells, which allow analyses to take place at the level of individually identified neurons. Individual neurons can be surgically removed and assayed for expression of membrane channels, levels of second messengers, protein phosphorylation, and RNA and protein synthesis. Moreover, peptides and nucleotides can be injected into individual neurons. Other invertebrate model systems such as Drosophila and Caenorhabditis elegans offer tremendous advantages for obtaining insights into the neuronal bases of behavior through the application of genetic approaches. The Oxford Handbook of Invertebrate Neurobiology reviews the many neurobiological principles that have emerged from invertebrate analyses, such as motor pattern generation, mechanisms of synaptic transmission, and learning and memory. It also covers general features of the neurobiology of invertebrate circadian rhythms, development, and regeneration and reproduction. Some neurobiological phenomena are species-specific and diverse, especially in the domain of the neuronal control of locomotion and camouflage. Thus, separate chapters are provided on the control of swimming in annelids, crustaea and molluscs, locomotion in hexapods, and camouflage in cephalopods. Unique features of the handbook include chapters that review social behavior and intentionality in invertebrates. A chapter is devoted to summarizing past contributions of invertebrates to the understanding of nervous systems and identifying areas for future studies that will continue to advance that understanding.
