Cognitive Biology


Book Description

In the past few decades, sources of inspiration in the multidisciplinary field of cognitive science have widened. In addition to ongoing vital work in cognitive and affective neuroscience, important new work is being conducted at the intersection of psychology and the biological sciences in general. This volume offers an overview of the cross-disciplinary integration of evolutionary and developmental approaches to cognition in light of these exciting new contributions from the life sciences. This research has explored many cognitive abilities in a wide range of organisms and developmental stages, and results have revealed the nature and origin of many instances of the cognitive life of organisms. Each section of this book deals with a key domain of cognition: spatial cognition; the relationships among attention, perception, and learning, representations of numbers and economic values; and social cognition. Contributors discuss each topic from the perspectives of psychology and neuroscience, brain theory and modeling, evolutionary theory, ecology, genetics, and developmental science.




The Synaptic Organization of the Brain


Book Description

It is widely recognized that the neural basis of brain function can be fully understood only by integrating many disciplines at many levels. Studies of synaptic organization are bringing about a quiet revolution in achieving this goal, as documented by this unique book over the past 30 years. In this fifth edition, the results of the mouse and human genome projects are incorporated for the first time. Molecular biologists interested in functional genomics and proteomics of the brain will find answers here to the critical questions: what are the cell and circuit functions of gene products? Also for the first time, the reader is oriented to supporting neuroscience databases. Among the new advances covered are 2-photon confocal laser microscopy of dendrites and dendritic spines, biochemical analyses, and dual patch and multielectrode recordings, applied together with an increasing range of behavioral and gene-targeting methods. Leading experts in the best understood brain regions bring together the molecular, anatomical, functional, and behavioral data in authoritative integrated accounts. The chapters are organized in the same format, covering the neural elements, synaptic connections, basic circuits, physiology, neurotransmitters, neuromodulators, membrane properties, dendritic properties, and with a final section on how the circuits mediate specific behaviors. The uniform framework for each chapter enables the authors to higlight the principles that are common to all regions, as well as the adaptations unique to each, thus serving as a model for understanding the neural basis of behavior.




Life's Ratchet


Book Description

Life, Hoffman argues, emerges from the random motions of atoms filtered through the sophisticated structures of our evolved machinery. People are essentially giant assemblies of interacting nanoscale machines.




Systems Biology


Book Description

The first comprehensive single-authored textbook on genome-scale models and the bottom-up approach to systems biology.




An Introduction to Systems Biology


Book Description

Thorough and accessible, this book presents the design principles of biological systems, and highlights the recurring circuit elements that make up biological networks. It provides a simple mathematical framework which can be used to understand and even design biological circuits. The textavoids specialist terms, focusing instead on several well-studied biological systems that concisely demonstrate key principles. An Introduction to Systems Biology: Design Principles of Biological Circuits builds a solid foundation for the intuitive understanding of general principles. It encourages the reader to ask why a system is designed in a particular way and then proceeds to answer with simplified models.




Neurogastronomy


Book Description

Leading neuroscientist Gordon M. Shepherd embarks on a paradigm-shifting trip through the "human brain flavor system," laying the foundations for a new scientific field: neurogastronomy. Challenging the belief that the sense of smell diminished during human evolution, Shepherd argues that this sense, which constitutes the main component of flavor, is far more powerful and essential than previously believed. Shepherd begins Neurogastronomy with the mechanics of smell, particularly the way it stimulates the nose from the back of the mouth. As we eat, the brain conceptualizes smells as spatial patterns, and from these and the other senses it constructs the perception of flavor. Shepherd then considers the impact of the flavor system on contemporary social, behavioral, and medical issues. He analyzes flavor's engagement with the brain regions that control emotion, food preferences, and cravings, and he even devotes a section to food's role in drug addiction and, building on Marcel Proust's iconic tale of the madeleine, its ability to evoke deep memories. Shepherd connects his research to trends in nutrition, dieting, and obesity, especially the challenges that many face in eating healthily. He concludes with human perceptions of smell and flavor and their relationship to the neural basis of consciousness. Everyone from casual diners and ardent foodies to wine critics, chefs, scholars, and researchers will delight in Shepherd's fascinating, scientific-gastronomic adventures.




A First Course in Systems Biology


Book Description

A First Course in Systems Biology is an introduction for advanced undergraduate and graduate students to the growing field of systems biology. Its main focus is the development of computational models and their applications to diverse biological systems. The book begins with the fundamentals of modeling, then reviews features of the molecular inventories that bring biological systems to life and discusses case studies that represent some of the frontiers in systems biology and synthetic biology. In this way, it provides the reader with a comprehensive background and access to methods for executing standard systems biology tasks, understanding the modern literature, and launching into specialized courses or projects that address biological questions using theoretical and computational means. New topics in this edition include: default modules for model design, limit cycles and chaos, parameter estimation in Excel, model representations of gene regulation through transcription factors, derivation of the Michaelis-Menten rate law from the original conceptual model, different types of inhibition, hysteresis, a model of differentiation, system adaptation to persistent signals, nonlinear nullclines, PBPK models, and elementary modes. The format is a combination of instructional text and references to primary literature, complemented by sets of small-scale exercises that enable hands-on experience, and large-scale, often open-ended questions for further reflection.
