Methods in neuronal modeling

Christof Koch,Idan Segev
Methods in Neuronal Modeling is the first technical handbook on computational neuroscience. Written for researchers and theoreticians alike, it outlines methods and techniques used for simulating on digital computers the functional properties of single neurons from synapses, dendrites, single cells; and small invertebrate networks to large scale neural networks in the mammalian nervous system. The use of new experimental tools such as selective staining methods, membrane patch electrodes, voltage and calcium-dependent dyes, and multielectrode recordings, together with the, advent of universally available powerful computing, makes it possible to construct detailed and realistic models of neuronal systems. Methods in Neuronal Modeling addresses such questions as what can and should be simulated and what techniques should be used; what experimental parameters are crucial for such simulations, and whether these models may be verified experimentally. Chapters cover simulation of passive dendritic trees, compartmental models of single cells including neurons with a number of different ionic channels, calcium current dynamics, simulations of small invertebrate networks, simulations of the mammalian cortex, connectionists' models, and the use of parallel computers in modeling neural networks. Although the chapters were written by several authors, they are uniform in structure and notation. Detailed examples are given to clarify the different approaches. Each chapter concludes with a description of the model discussed and the details of its implementation on the computer. Christof Koch is an Assistant Professor of Computation and Neural Systems at the California Institute of Technology. Idan Segev is a Lecturer in Neurobiology at the Institute of Life Science, Hebrew University of Jerusalem. Methods in Neuronal Modeling inaugurates the new series in Computational Neuroscience, edited by Terrence J. Sejnowski and Tomaso Poggio. A Bradford Book.

The Hologenome Concept: Human, Animal and Plant Microbiota

Eugene Rosenberg,Ilana Zilber-Rosenberg
Groundbreaking research over the last 10 years has given rise to the hologenome concept of evolution. This concept posits that the holobiont (host plus all of its associated microorganisms) and its hologenome (sum of the genetic information of the host and its symbiotic microorganisms), acting in concert, function as a unique biological entity and therefore as a level of selection in evolution. All animals and plants harbor abundant and diverse microbiota, including viruses. Often the amount of symbiotic microorganisms and their combined genetic information far exceed that of their host. The microbiota with its microbiome, together with the host genome, can be transmitted from one generation to the next and thus propagate the unique properties of the holobiont. The microbial symbionts and the host interact in a cooperative way that affects the health of the holobiont within its environment. Beneficial microbiota protects against pathogens, provides essential nutrients, catabolizes complex polysaccharides, renders harmful chemicals inert, and contributes to the performance of the immune system. In humans and animals, the microbiota also plays a role in behavior. The sum of these cooperative interactions characterizes the holobiont as a unique biological entity. Genetic variation in the hologenome can be brought about by changes in either the host genome or the microbial population genomes (microbiome). Evolution by cooperation can occur by amplifying existing microbes, gaining novel microbiota and by acquiring microbial and viral genes. Under environmental stress, the microbiome can change more rapidly and in response to more processes than the host organism alone and thus influences the evolution of the holobiont. Prebiotics, probiotics, synbiotics and phage therapy are discussed as applied aspects of the hologenome concept.

Slanted Truths: Essays on Gaia, Symbiosis and Evolution

Margulis, Lynn,Sagan, Dorion
This enticing collection is as devoted to the profound power of figures of speech as any oration of old Hellas. Metaphor reigns as we encounter the identification of our Earth as a Single, integrative organism, a tale told in image and passion. The discoveries and conjectures upon which this grand view rest are here as well. I have enjoyed these two dozen pieces hugely. No family tree of animal life but must somewhere disclose a cousinly infolding. We are compact of life past, and the looped handing down is more complex than the Mendel-Morgan dance of chromosomes and genes. That dance is essential, certainly, but it is the vital editing of an epic and many-rooted work, a book more like the Bible than like one great artists Remembrance of Things Past. We follow a few old shelves of bound DNA, not just a single book. Our major biochemical package for oxidative metabolism was de scribed in a small DNA manual, somehow engulfed to become an or ganelle within a lucky ancient ancestral anaerobe, and passed ever since viii FOREWORD from mother to offspring outside of the chromosome shuffie. The sperm do carry half the compact genetic message of the human DNA, but they are too small to transfer this equally essential symbiotic one that comes down from the mothers, within roomy egg after roomy egg.

The dialectical biologist

Levins, Richard
Scientists act within a social context and from a philosophical perspective that is inherently political. Whether they realize it or not, scientists always choose sides. The Dialectical Biologist explores this political nature of scientific inquiry, advancing its argument within the framework of Marxist dialectic. These essays stress the concepts of continual change and codetermination between organism and environment, part and whole, structure and process, science and politics. Throughout, this book questions our accepted definitions and biases, showing the self-reflective nature of scientific activity within society.

The Astonishing Elephant

Shana Alexander
the Astonishing Elephant is an unabashed celebration of these mysterious creatures, whose closest living relatives are the dugong and the hyrax. "they have," Alexander writes, "essential nobility,grace, serenity, sagacity, loyalty and playfulness, a simple goodness, a alack of animosity - unless provoked." While she admits elephants can pose particular dangers to unwary humans (she recounts tales of circus trainers of her acquaintance, some of whom fell in action), they are too often the victims in any interaction with people. the elephant's fortunes have long been declining: where only a few thousand years ago several species roamed the earth, by 1980 the combined wild populations in Africa and Asia numbered fewer than 100,000 individuals.

Metamorphosis: a natural and human history

Harman, Oren Solomon
""How many creatures walking on this earth / Have their first being in another form?" the Roman poet Ovid asked two thousand years ago. He could not have known the full extent of the truth: Today, biologists estimate a stunning three-quarters of all animal species on earth undergo some form of metamorphosis. But why do tadpoles transform into frogs, caterpillars into butterflies, elvers into eels, immortal jellyfish from sea sprigs to medusae and back again, growing younger and younger in frigid ocean depths? Why must creatures go through massive destruction and remodeling to become who they are? Tracing a path from Aristotle--who rejected the possibility of metamorphosis--to Darwin to today, historian of science Oren Harman explores that central mystery. Metamorphosis, however, isn't just a biological puzzle: It takes us to the very heart of questions of being and identity, whatever kind of change we may undergo. Metamorphosis is a new classic of natural history: a book that, by unveiling a mystery of nature, causes us to relearn ourselves"--Publisher's description.

Five kingdoms: an illustrated guide to the phyla of life on earth

Margulis, Lynn
An all-inclusive catalogue of the world's living diversity, Five Kingdoms defines and describes the major divisions, or phyla, of nature's five great kingdoms - bacteria, protoctists, animals, fungi, and plants - using a modern classification scheme that is consistent with both the fossil record and molecular data. Generously illustrated and remarkably easy to follow, it not only allows readers to sample the full range of life forms inhabiting our planet but to familiarize themselves with the taxonomic theories by which all organisms' origins and distinctive characteristics are traced and classified.

On Giving Up

Adam Phillips
One of The New York Times Critics' Picks of the Year From acclaimed psychoanalyst Adam Phillips, a meditation on what we must give up to feel more alive. To give up or not to give up? The question can feel inescapable but the answer is never simple. Giving up our supposed vices is one thing; giving up on life itself is quite another. One form of self-sacrifice feels positive, something to admire and aspire to, while the other is profoundly unsettling, if not actively undesirable. There are always, it turns out, both good and bad sacrifices, but it is not always clear beforehand which is which. We give something up because we believe we can no longer go on as we are. In this sense, giving up is a critical moment—an attempt to make a different future. In On Giving Up , the acclaimed psychoanalyst Adam Phillips illuminates both the gaps and the connections between the many ways of giving up and helps us to address the central question: What must we give up in order to feel more alive?
