This volume contains the proceedings of a workshop on Analog Integrated Neural Systems held May 8, 1989, in connection with the International Symposium on Circuits and Systems. The presentations were chosen to encompass the entire range of topics currently under study in this exciting new discipline. Stringent acceptance requirements were placed on contributions: (1) each description was required to include detailed characterization of a working chip, and (2) each design was not to have been published previously. In several cases, the status of the project was not known until a few weeks before the meeting date. As a result, some of the most recent innovative work in the field was presented. Because this discipline is evolving rapidly, each project is very much a work in progress. Authors were asked to devote considerable attention to the shortcomings of their designs, as well as to the notable successes they achieved. In this way, other workers can now avoid stumbling into the same traps, and evolution can proceed more rapidly (and less painfully). The chapters in this volume are presented in the same order as the corresponding presentations at the workshop. The first two chapters are concerned with fmding solutions to complex optimization problems under a predefmed set of constraints. The first chapter reports what is, to the best of our knowledge, the first neural-chip design. In each case, the physics of the underlying electronic medium is used to represent a cost function in a natural way, using only nearest-neighbor connectivity.

How developments in science and technology may enable the emergence of purely digital minds—intelligent machines equal to or greater in power than the human brain. What do computers, cells, and brains have in common? Computers are electronic devices designed by humans; cells are biological entities crafted by evolution; brains are the containers and creators of our minds. But all are, in one way or another, information-processing devices. The power of the human brain is, so far, unequaled by any existing machine or known living being. Over eons of evolution, the brain has enabled us to develop tools and technology to make our lives easier. Our brains have even allowed us to develop computers that are almost as powerful as the human brain itself. In this book, Arlindo Oliveira describes how advances in science and technology could enable us to create digital minds. Exponential growth is a pattern built deep into the scheme of life, but technological change now promises to outstrip even evolutionary change. Oliveira describes technological and scientific advances that range from the discovery of laws that control the behavior of the electromagnetic fields to the development of computers. He calls natural selection the ultimate algorithm, discusses genetics and the evolution of the central nervous system, and describes the role that computer imaging has played in understanding and modeling the brain. Having considered the behavior of the unique system that creates a mind, he turns to an unavoidable question: Is the human brain the only system that can host a mind? If digital minds come into existence—and, Oliveira says, it is difficult to argue that they will not—what are the social, legal, and ethical implications? Will digital minds be our partners, or our rivals?

We've come so far, so fast. Within a relatively short period of time, we've managed to put enormous computing power in offices and homes around the globe. But before there was an IBM computer, before there were laptops and personal PCs, there were small independent teams of pioneers working on the development of the very first computer. Scattered around the globe and ranging in temperament and talent, they forged the future in basement labs, backyard, workshops, and old horse barns. Tracing the period just after World War II when the first truly modern computers were developed, Electronic Brains chronicles the escapades of the world's first "techies." Some of the initial projects are quite famous and well known, such as "LEO", the Lyons Electronic Office, which was developed by the catering company J. Lyons & Co. in London in the 1940s. Others are a bit more arcane, such as the ABC, which was built in a basement at Iowa State College and was abandoned to obscurity at the beginning of WWII. And then - like the tale of the Rand 409 which wss constructed in a barn in Connecticut under the watchful eye of a stuffed moose - there are the stories that are virtually unknown. All combine to create a fascinating history of a now-ubiquitous technology. Relying on extensive interviews from surviving members of the original teams of hardware jockeys, author Mike Hally recreates the atmosphere of the early days of computing. Rich with provocative and entertaining descriptions, we are introduced go the many eccentric, obsessive, and fiercely loyal men and women who laid the foundations for the computerized world in which we now live. As the acronyms fly fast and furious - UNIVAC, CSIRAC, and MESM, to name just a few - Electronic Brains provides a vivid sense of time, place, and science.

The story of a neural impulse and what it reveals about how our brains work We see the last cookie in the box and think, can I take that? We reach a hand out. In the 2.1 seconds that this impulse travels through our brain, billions of neurons communicate with one another, sending blips of voltage through our sensory and motor regions. Neuroscientists call these blips “spikes.” Spikes enable us to do everything: talk, eat, run, see, plan, and decide. In The Spike, Mark Humphries takes readers on the epic journey of a spike through a single, brief reaction. In vivid language, Humphries tells the story of what happens in our brain, what we know about spikes, and what we still have left to understand about them. Drawing on decades of research in neuroscience, Humphries explores how spikes are born, how they are transmitted, and how they lead us to action. He dives into previously unanswered mysteries: Why are most neurons silent? What causes neurons to fire spikes spontaneously, without input from other neurons or the outside world? Why do most spikes fail to reach any destination? Humphries presents a new vision of the brain, one where fundamental computations are carried out by spontaneous spikes that predict what will happen in the world, helping us to perceive, decide, and react quickly enough for our survival. Traversing neuroscience’s expansive terrain, The Spike follows a single electrical response to illuminate how our extraordinary brains work.

Increasing numbers of parents grapple with children who are acting out without obvious reason. Revved up and irritable, many of these children are diagnosed with ADHD, bipolar illness, autism, or other disorders but don’t respond well to treatment. They are then medicated, often with poor results and unwanted side effects. Based on emerging scientific research and extensive clinical experience, integrative child psychiatrist Dr. Victoria Dunckley has pioneered a four-week program to treat the frequent underlying cause, Electronic Screen Syndrome (ESS). Dr. Dunckley has found that everyday use of interactive screen devices — such as computers, video games, smartphones, and tablets — can easily overstimulate a child’s nervous system, triggering a variety of stubborn symptoms. In contrast, she’s discovered that a strict, extended electronic fast single-handedly improves mood, focus, sleep, and behavior, regardless of the child’s diagnosis. It also reduces the need for medication and renders other treatments more effective. Offered now in this book, this simple intervention can produce a life-changing shift in brain function and help your child get back on track — all without cost or medication. While no one in today’s connected world can completely shun electronic stimuli, Dr. Dunckley provides hope for parents who feel that their child has been misdiagnosed or inappropriately medicated, by presenting an alternative explanation for their child’s difficulties and a concrete plan for treating them.

This book represents the views of one of the greatest mathematicians of the twentieth century on the analogies between computing machines and the living human brain. John von Neumann concludes that the brain operates in part digitally, in part analogically, but uses a peculiar statistical language unlike that employed in the operation of man-made computers. This edition includes a new foreword by two eminent figures in the fields of philosophy, neuroscience, and consciousness.
