Body and Brain
A Trophic Theory of Neural Connections
Dale Purves
Harvard University Press, 1988

The major goal of developmental neurobiology is to understand how the nervous system is put together. A central theme that has emerged from research in this field over the last several decades is the crucial role of trophic interactions in neural assembly, and indeed throughout an animal's life. Trophic—which means nutritive—refers to long-term interdependencies between nerve cells and the cells they innervate.

The theory of trophic effects presented in this book offers an explanation of how the vertebrate nervous system is related to—and regulated by—the body it serves. The theory rationalizes the nervous system's accommodation, throughout life, to the changing size and form of the body it tenants, indicating the way connections between nerve cells change in response to stimuli as diverse as growth, injury, experience, and natural selection.

Dale Purves, a leading neurobiologist best known for his work on the formation and maintenance of synaptic connections, presents this theory within the historical setting of earlier ideas about neural organization—from Weiss's theory of functional reorganization to the chemoaffinity theory championed by Sperry. In addition to illuminating eighty years of work on trophic interactions, this book asks its own compelling questions: Are trophic interactions characteristic of all animals or only of those with complex nervous systems? Are trophic interactions related to learning? What does the trophic theory of neural connections imply about the currently fashionable view that the nervous system operates according to Darwinian principles?

Purves lays the theoretical foundation for practical exploration of trophic interactions as they apply to neural connections, a pursuit that will help us understand how our own nervous systems generate change. The ideas in this book not only enrich neurobiology but also convey the profound relevance of neuroscience to other fields of life science.

Governing Behavior
How Nerve Cell Dictatorships and Democracies Control Everything We Do
Ari Berkowitz
Harvard University Press, 2016

From simple reflexes to complex choreographies of movement, all animal behavior is governed by a nervous system. But what kind of government is it—a dictatorship or a democracy?

Nervous systems consist of circuits of interconnected nerve cells (neurons) that transmit and receive information via electrical signals. Every moment, each neuron adds up stimulating and inhibiting inputs from many other neurons to determine whether to send an electrical signal to its recipients. Some circuits are dominated by a single “dictator” neuron that gathers information from many sources and then issues commands, such as the Mauthner neuron that triggers escape in fish. In other more “democratic” circuits, such as those mediating eye movements in monkeys, the outcome is determined by a tally of “votes” from a large population of neurons. Rhythmic movements like breathing and locomotion are generated by “government programs” within the central nervous system, but modified by a soup of chemicals and by free market–like feedback from sensory neurons. Nervous systems also use sophisticated surveillance of the surrounding environment and keep track of their own decisions in order to avoid internal conflicts. Nervous systems are not restricted to using one set of procedures at a time. They have evolved over long periods to control behaviors in whichever ways are most effective, and they essentially combine multiple forms of government simultaneously.

Engaging and accessible, Governing Behavior explains the variety of structures and strategies that control behavior, while providing an overview of thought-provoking debates and cutting-edge research in neurobiology.

Molecular and Cellular Physiology of Neurons
Gordon L. Fain
Harvard University Press, 1999

If we are to understand the brain, we must understand how the individual molecules and cells of the nervous system function and ultimately contribute to our behavior. Molecular and Cellular Physiology of Neurons provides a comprehensive and up-to-date account of what we now know—and what we want to know and can reasonably expect to discover in the near future—about the functioning of the brain at the level of molecules and cells.

Molecular and Cellular Physiology of Neurons takes readers from the fundamentals to the most sophisticated concepts and latest discoveries: from membrane potentials to recent experiments on voltage-gated ion channels, from descriptions of receptors, G proteins, effector molecules, and second messengers to an account of our current understanding of long-term potentiation.

In each chapter Fain discusses individual experiments that have made crucial contributions to our knowledge and that illustrate the techniques and approaches that have formed our present view of nerve cell function. Extensive illustrations add to this vivid account of not only what we know about cellular and molecular neurophysiology but how we know it.

Molecular and Cellular Physiology of Neurons
Second Edition
Gordon L. Fain, illustrated by Margery J. Fain
Harvard University Press, 2014

Molecular and Cellular Physiology of Neurons: Second Edition is a comprehensive, up-to-date introduction to essential concepts of cellular neuroscience. Emphasizing experimental approaches and recent discoveries, it provides an in-depth look at the structure and function of nerve cells, from protein receptors and synapses to the biochemical processes that drive the mammalian nervous system.

Starting with the basics of electrical current flow across cell membranes, Gordon Fain covers voltage gating and receptor activation in the context of channel diversity, excitatory and inhibitory synaptic transmission, neuromodulation, and sensory transduction. Emphasizing long-term processes of synaptic potentiation and depression involved in memory, consciousness, and attention, he demonstrates how cells produce neural signals and regulate signal flow to enhance or impede cell-to-cell communication. Fain also addresses the relation of molecular and cellular mechanisms to evolving theories of neurological disease and addiction.

Enhanced by more than two hundred illustrations, Molecular and Cellular Physiology of Neurons: Second Edition is intended for anyone who seeks to understand the fundamentals of nerve cell function, including undergraduate and graduate students in neuroscience, students of bioengineering and cognitive science, and practicing neuroscientists who want to deepen their knowledge of recent discoveries in molecular and cellular neurophysiology.

Neurons and Networks
An Introduction to Behavioral Neuroscience, Second Edition
John E. Dowling
Harvard University Press, 2001

Harvard University Press is proud to announce the second edition of a widely admired introductory textbook. When first published, Neurons and Networks filled the need for an introductory neuroscience text that is lucid, accessible, authoritative, logically organized, and concise. Avoiding the encyclopedic coverage that makes most neuroscience texts overwhelming, Neurons and Networks focused instead on building the solid foundation of understanding and knowledge required for further study.

The new edition retains the features that made the first edition so attractive: consistent emphasis on results and concepts that have stood the test of time; abundant high-quality illustrations; exceptionally clear explanations of technical terms. Completely revised and enlarged with six new chapters, the second edition of Neurons and Networks is an introduction not just to neurobiology, but to all of behavioral neuroscience. It is an ideal text for first- or second-year college students with minimal college science exposure. It is also an invaluable resource for students in biology, psychology, anthropology, and computer science who seek an accessible guide to a discipline that will be a critically important area of research in the twenty-first century.
