Yale H. Ferguson , and Richard W. Mansbach Manufacturer: Cambridge University Press ProductGroup: Book Binding: Paperback Similar Items:
ASIN: 0521549914 |
Book Description
Yale Ferguson and Richard Mansbach suggest that the state is losing its capacity, legitimacy and authority to remain the primary actor in world affairs and is being transformed into a more complex "post-international universe" characterized by diverse and overlapping polities. Ferguson and Mansbach, accordingly, revise the "maps" of global politics and explain the shifting and accelerating forces transforming them in an important contribution to the issues of globalization and the future of international relations theory.

Biophysics of Computation: Information Processing in Single Neurons (Computational Neuroscience)
Christof Koch Manufacturer: Oxford University Press, USA ProductGroup: Book Binding: Paperback Similar Items:
ASIN: 0195181999 |
Book Description
Neural network research often builds on the fiction that neurons are simple linear threshold units, completely neglecting the highly dynamic and complex nature of synapses, dendrites, and voltage-dependent ionic currents. Biophysics of Computation: Information Processing in Single Neurons challenges this notion, using richly detailed experimental and theoretical findings from cellular biophysics to explain the repertoire of computational functions available to single neurons. The author shows how individual nerve cells can multiply, integrate, or delay synaptic inputs and how information can be encoded in the voltage across the membrane, in the intracellular calcium concentration, or in the timing of individual spikes. Key topics covered include the linear cable equation; cable theory as applied to passive dendritic trees and dendritic spines; chemical and electrical synapses and how to treat them from a computational point of view; nonlinear interactions of synaptic input in passive and active dendritic trees; the Hodgkin-Huxley model of action potential generation and propagation; phase space analysis; linking stochastic ionic channels to membrane-dependent currents; calcium- and potassium-currents and their role in information processing; the role of diffusion, buffering and binding of calcium, and other messenger systems in information processing and storage; short- and long-term models of synaptic plasticity; simplified models of single cells; stochastic aspects of neuronal firing; the nature of the neuronal code; and unconventional models of sub-cellular computation. Biophysics of Computation: Information Processing in Single Neurons serves as an ideal text for advanced undergraduate and graduate courses in cellular biophysics, computational neuroscience, and neural networks, and will appeal to students and professionals in neuroscience, electrical and computer engineering, and physics.Customer Reviews:
Single Neuron Computational Modeling.......2004-06-11
How smart is a neuron?.......2004-04-15
All of the above comprises an extended introduction to Chapters 17 to 19, which: `synthesize the previously learned lessons into a complete account of the events occurring in realistic dendritic trees with all of their attendant nonlinearities'. `We will see', the author writes, `that dendrites can indeed be very powerful, nontraditional computational devices, implementing a number of continuous operations.' Thus Biophysics of Computation offers a definitive statement for the direction in which the neural research of the new century should go. Chapter 20, the penultimate, discusses several speculations for non-neural computation in the brain, ranging from molecular computing below the level of a single neuron to the effects of chemical diffusants (nitric oxide, calcium ions, carbon monoxide, etc.) on large numbers of neurons. Although this entire area has been neglected by most of the neuroscience community, Koch points out that there are no good reasons for doing so. As we enter the new century, neuroscientists should keep their minds open. Finally, in the summary of Chapter 21, seven problems for future research projects are listed, emphasizing that the investigation of information processing in single neurons is very much a work in progress. It is of interest to examine these `strategic questions' as they reveal the author's intuitions about possible directions of future developments. (Note that these are not direct quotes, as I have taken the liberty of summarizing Koch's questions.)
(1) How can the operation of multiplication be implemented at the level of a single neuron?
(2) What are the sources of noise in a neural system and how does this noise influence the logical operation of a single neuron?
(3) How is the style of neural computation influenced by metabolic considerations?
(4) What is the function of the apical dendrite, which is a typical cortical structure?
(5) How and where does learning actually take place in a neural system?
(6) What are the functions of the dendritic trees, the forms of which vary so widely from neuron to neuron?
(7) How can we construct neural models that are sufficiently realistic to capture the essential functions of real neurons yet simple enough to allow large-scale computations of brain dynamics?
As these questions indicate, Koch is not merely concerned with understanding
what unusual behaviours the neuron does or might exhibit. His broad aim is to comprehend the relation between this behavioural ability and the computational tasks that the neuron is called upon to perform. In his words:
``Thinking about brain style computation requires a certain frame of mind, related to but distinctly different from that of the biophysicist. For instance, how should we think of a chemical synapse? In terms of complicated pre- and post-synaptic elements? Ionic channels? Calcium binding proteins? Or as a non-reciprocal and stochastic switching device that transmits a binary signal rapidly between two neurons and remembers its history of usage? The answer is that we must be concerned with both aspects, with biophysics as well as computation.''
This excellent book is evidently a labour of love, stemming from the author's 1982 doctoral thesis on information processing in dendritic trees. As far as I can tell all relevant aspects of neural processing are considered, with what seem to me to be just the proper amounts of emphasis. The writing style is precise and rigorous without being stuffy, and the many references to a fifty-page bibliography will be of enormous value to young researchers starting out in this field.
In addition to its obvious value for those engaged in experimental, theoretical or numerical studies of neuronal behaviour Biophysics of Computation would also work well as the text for an introductory course in neural dynamics, perhaps as part of a neuroscience program.

brief & comprehensive.......2001-07-07
We don't know much about biological neurons. We don't really understand how they perform computation. Yet we have some models, approximations of the models, and theories of how the model neurons get organized to do computation. These are summarized in this book in a breif & comprehensive manner.
Some notes: 1) Portions of the book may be found in greater detail elsewhere. 2) The book is more about biophysics than compuation.
Excellent, a good place to start.......2000-04-30
The possibility exists that the neuron is a multichannel device, a cable rather than a wire. The model is attractive because a multichannel nerve would enable us to think as fast as we do. Because nerve impulses are so very slow moving, each successive impulse might, (contrary to everything we thought we knew) be rich in information. A multichannel neuron has the power to convey, with each single all-or-nothing impulse, graded information. For example, to 20 discrete channels, one can assign 20 distinct tiers of meaning, and each channel can thus "mean" a level of intensity between 1 and 20. The phenomenon can easily escape detection because such a neuron appears, to conventional instruments, to convey only the classically blank, binary impulse that is so confidently presented to us on the first page of every neurobiology text, and in summary in this book as well.
To create a continuous longitudinal information channel running the full length of an axon membrane, one would simply link each ion portal to its next door neighbor. A conformation change in one portal induces a conformation change in the next in line. A domino effect more intuitively satisfying, perhaps, than the familiar waveguide or cable models of membrane depolarization reiterated here.
One can visualize many parallel tracks, a corduroy membrane. Possibly linear, possibly helical. Linked receptors are commonplace. The molecular structure of the potassium channel has been published recently, and so we are now finally working at the level where a multichannel membrane can be detected. It is a theoretical construct but if each single impulse carries information, then the computational burden on the nervous system is vastly reduced, and the physiological meaning of intensively studied structures like the synapse suddenly changes. The meaning of several of the models presented in this book also changes, often in quite intriguing ways.

Comics, Comix & Graphic Novels: A History Of Comic Art

For many years, those interested in the history of the art of comics--from scholars to fans--had very few options. The available books were either filled with glaring errors or far too limited in their scope. Along comes Roger Sabin and his near-definitive history. The best thing about this book is that it begins with a strong foundation--that comics is a separate and unique artistic medium--and goes on to leave practically no stone unturned, from mainstream superheroes to underground work to Japanese manga to the new alternatives to the strong European tradition. There's even an entire chapter on comics by and aimed toward women, hopefully dispelling the myth that comics are just for boys.Book Description

Rebel Visions: The Underground Comix Revolution, 1963-1975
Patrick Rosenkranz Manufacturer: Fantagraphics Books ProductGroup: Book Binding: Hardcover Similar Items:
ASIN: 1560974648 |
Book Description
The first major historical work about the most influential artistic movement in America since the Beat Generation revolutionized literature.A provocative chronicle of the guerrilla art movement that changed comics forever, this comprehensive book follows the movements of 50 artists from 1967 to 1972, the heyday of the underground comix movement. Through interviews with the participants and other materials, Rebel Visions is the most intimate look ever at the people and events that forged the phenomenon known as underground comix, from New York to San Francisco, from the corn belt to deep in the heart of Texas, beginning that day in 1968 when R. Crumb debuted Zap #1 from a baby carriage on Haight Ashbury Street. Rosenkranz has spent 20 years researching this book and acquiring the cooperation of every significant underground cartoonist who worked throughout this period, including Crumb, Gilbert Shelton (Fabulous Furry Freak Brothers), Bill Griffith (Zippy the Pinhead), Art Spiegelman (Maus), Jack Jackson, S. Clay Wilson, Robert Williams, and many more. The book is illustrated with many never-before-seen drawings by all of the underground cartoonists, and exclusive photographs.
The book focuses on San Francisco's Haight-Ashbury district, where Crumb and the rest of his Zap cronies commingled with the rest of the city's counter-cultural scene, notably musicians like the Grateful Dead and Janis Joplin. The counterculture was omnipresent in San Francisco for those few years, with underground tabloids like Yellow Dog and Gothic Blimp Works steering the zeitgeist out-of-control, along with the music, political, and psychedelic drug scenes, all of which found a group of unlikely revolutionaries who drew cartoons right at the epicenter.
"It did feel like this must have been what the cubists were going through, like all the magic of being in Paris for the post-Impressionistic movement did feel somehow like being in San Francisco in the early 1970s." Art Spiegelman, from Rebel Visions
"Like any utopian experiment, ideals were challenged and rewritten in the face of the daily grind. It was a harsh life lesson for me, but there were lots of laughs and some beautiful times, too..." Justin Green, from Rebel Visions
"Underground comics were more like art and less like comics." Gilbert Shelton, from Rebel Visions

The Inside Scoop.......2004-01-02
For those who are familiar with underground comic books, Patrick Rosenkranz has provided an amazing amount of background information about the creators and the times that produced what could be viewed as the trashiest and/or the most significant cultural artifacts of the second half of the 20th Century.
Unlike previous histories and articles that simply reprint the more or less shocking comic pages and regurgitate the same old information, misinformation and opinions about the hippies and their graphic art, Rebel Visions is based on Mr. Rosenkranz own interviews and correspondence with the first wave of underground comix creators. In lengthy footnoted quotes, the artist/writers are finally allowed to tell their own strange and wonderful stories. And by following the stories organized in yearly chapters, I cames to understand something of the birth, bloom and demise of a phenomena that never made the transition to mainstream product or the 1980s.
Rebel Visions also presents a significant amount of previously unpublished art for the connoisseur as well as an exhaustive index for the scholar.
A word of warning: these comic books are not, and never were, intended for children. Most of the comix displayed and discussed in Rebel Visions were all about breaking taboos, about freedom of expression in the face of a repressive mainstream culture and not about tittilation. That came later. If you're interested in cartoons, graphic art, the counter culture, art, politics, the sixties, propaganda, freedom and censorship, as well as the usual sex, drugs and war, check it out.
