This volume presents the latest research in the broad field of the chemical senses from the International Symposium on Olfaction and Taste. This field includes not only the obvious senses of taste and smell but also chemical irritation and related sensations. Scientists investigate the mechanisms and functions of the chemical senses in the oral and nasal cavity as well as in the viscera including the gut and airways. This volume takes an integrative approach and provides historical context for modern research in the field. NOTE: Annals volumes are available for sale as individual books or as a journal.

The collection of chapters in this book present the concept of matched filters: response characteristics “matching” the characteristics of crucially important sensory inputs, which allows detection of vital sensory stimuli while sensory inputs not necessary for the survival of the animal tend to be filtered out, or sacrificed. The individual contributions discuss that the evolution of sensing systems resulted from the necessity to achieve the most efficient sensing of vital information at the lowest possible energetic cost. Matched filters are found in all senses including vision, hearing, olfaction, mechanoreception, electroreception and infrared sensing and different cases will be referred to in detail.
Microcircuits are the specific arrangements of cells and their connections that carry out the operations unique to each brain region. This resource summarizes succinctly these circuits in over 40 regions - enabling comparisons of principles across both vertebrates and invertebrates. It provides a new foundation for understanding brain function that will be of interest to all neuroscientists. Oxford Clinical Neuroscience is a comprehensive, cross-searchable collection of resources offering quick and easy access to eleven of Oxford University Press's prestigious neuroscience texts. Joining Oxford Medicine Online these resources offer students, specialists and clinical researchers the best quality content in an easy-to-access format.
Debating New Approaches to the History of Science explores the big questions in the history of science and the main problems and challenges it is facing today. In each chapter, established and emerging scholars introduce new approaches to the history of science and revisit older perspectives which remain crucial, before providing a critical analysis of the perspective. The volume looks at topics such as the importance of the 'environmental turn' for the history of science and the possibilities for the field of moving beyond a focus on ideas and texts towards active engagement with materials and practices. It asks important questions such as 'what does it mean to study science's past in the A...
The author of the game-changing Cannabis Health Index returns with a book designed specifically for general readers who want to understand how THC and CBD can benefit them. While CBD is the new buzzword for health and wellness, many researchers and practitioners believe that the symbiotic relationship between THC and CBD, known as the entourage effect, allows for greater therapeutic benefits for patients. Unfortunately, when it comes to optimizing that ratio to a particular health condition, it is often a process of trial and error for medical patients. Your Cannabis CBD:THC Ratio provides detailed information on how to find the best ratios of CBD:THC and covers the preferred ratios of these two primary cannabinoids for ten prevalent medical conditions —including cancer, chronic pain, anxiety, insomnia, and many others. Blesching’s unique chemotype-based system takes into account CBD:THC ratios, the various forms of cannabis medicine available to consumers, and the subjective therapeutic dosages, presenting a complete evidence-based methodology. -- Uwe Blesching, PH.D.

Animals rely on sensory input from their environment for survival and reproduction. Depending on the importance of a signal for a given species, accuracy of sensory coding might vary from pure detection up to precise coding of intensity, quality and temporal features of the signal. Highly sophisticated sense organs and related central nervous sensory pathways can be of utmost importance for animals in a complex environment and when using advanced communication systems. In sensory systems different anatomical and physiological features have evolved to optimally encode behaviourally relevant signals at the level of sense organs and central processing. The wide range of organizational complexit...
Olfaction and taste are of critical importance to insects and other animals, since vital behaviours, including mate, food and host seeking, as well as predator and toxin avoidance, are guided by chemosensory cues. Mate and habitat choice are to a large extent determined by chemical signals, and chemoreceptors contribute accordingly to pre-mating isolation barriers and speciation. In addition to fundamental physiological, ecological and evolutionary consideration, the knowledge of insect taste and especially olfaction is also of great importance to human economies, since it facilitates a more informed approach to the management of insect pests of agricultural crops and forests, and insect vec...
