The Illusory Boundary

This compelling new book challenges the view that a clear and unwavering boundary exists between nature and technology. Rejecting this dichotomy, the contributors show how the history of each can be united in a constantly shifting panorama where definitions of "nature" and "technology" alter and overlap.

The view of nature and technology inhabiting totally different, even opposite, spheres persists across time and cultures. Most people would consider an English countryside or a Louisiana bayou to be "natural," though each is to an extent the product of technology. Pollution, widely thought to be a purely man-made phenomenon, results partly from natural processes. All around us, things from the natural world are brought into the human world. At what point do we consider them part of culture rather than nature? And does such a distinction illuminate our world or obscure its workings? This compelling new book challenges the view that a clear and unwavering boundary exists between nature and technology. Rejecting this dichotomy, the contributors show how the history of each can be united in a constantly shifting panorama where definitions of "nature" and "technology" alter and overlap. In addition to recognizing the artificial divide between these two concepts, the essays in this book demonstrate how such thinking may affect societies’ ability to survive and prosper. The answers and ideas are as numerous as the landscapes they consider, for there is no single path toward a more harmonious vision of technology and nature. Technologies that work in one place may not in another. Nature that is preserved in one community might become the raw material of technological progress somewhere else. Add to this the fact that the natural world and technology are not passive players, but are profoundly involved in cultural construction. Understanding such dynamics not only reveals a new historical complexity; it prepares us for coping with many of the most difficult and pressing social issues facing us today.

Visual illusions are compelling phenomena that draw attention to the brain's capacity to construct our perceptual world. The Compendium is a collection of over 100 chapters on visual illusions, written by the illusion creators or by vision scientists who have investigated mechanisms underlying the phenomena. --

How does your mind work? How does your brain give rise to your mind? These are questions that all of us have wondered about at some point in our lives, if only because everything that we know is experienced in our minds. They are also very hard questions to answer. After all, how can a mind understand itself? How can you understand something as complex as the tool that is being used to understand it? This book provides an introductory and self-contained description of some of the exciting answers to these questions that modern theories of mind and brain have recently proposed. Stephen Grossberg is broadly acknowledged to be the most important pioneer and current research leader who has, for the past 50 years, modelled how brains give rise to minds, notably how neural circuits in multiple brain regions interact together to generate psychological functions. This research has led to a unified understanding of how, where, and why our brains can consciously see, hear, feel, and know about the world, and effectively plan and act within it. The work embodies revolutionary Principia of Mind that clarify how autonomous adaptive intelligence is achieved. It provides mechanistic explanations of multiple mental disorders, including symptoms of Alzheimer's disease, autism, amnesia, and sleep disorders; biological bases of morality and religion, including why our brains are biased towards the good so that values are not purely relative; perplexing aspects of the human condition, including why many decisions are irrational and self-defeating despite evolution's selection of adaptive behaviors; and solutions to large-scale problems in machine learning, technology, and Artificial Intelligence that provide a blueprint for autonomously intelligent algorithms and robots. Because brains embody a universal developmental code, unifying insights also emerge about shared laws that are found in all living cellular tissues, from the most primitive to the most advanced, notably how the laws governing networks of interacting cells support developmental and learning processes in all species. The fundamental brain design principles of complementarity, uncertainty, and resonance that Grossberg has discovered also reflect laws of the physical world with which our brains ceaselessly interact, and which enable our brains to incrementally learn to understand those laws, thereby enabling humans to understand the world scientifically. Accessibly written, and lavishly illustrated, Conscious Mind/Resonant Brain is the magnum opus of one of the most influential scientists of the past 50 years, and will appeal to a broad readership across the sciences and humanities.

A straightforward and accessible study of personal development and human consciousness, as seen through the lens of Eastern and Western therapeutic traditions A simple yet comprehensive guide to the types of psychologies and therapies available from Eastern and Western sources. Each chapter includes a specific exercise designed to help the reader understand the nature and practice of the specific therapies. Wilber presents an easy-to-use map of human consciousness against which the various therapies are introduced and explained. This edition includes a new preface.

Starting from psychophysics, over the last 50 years, most progress in unravelling the mechanisms of color vision has been made through the study of single cell responses, mainly in LGN and striate cortex. A similar development in the study of form perception may seem to be underway, centred on the study of temporal cortex. However, because of the combinatorial characteristics of form perception, we are also observing the opposite tendency: from single-cell activity to population coding, and from static receptive field structures to system dynamics and integration and, ultimately, a synthetic form of psychophysics of color and form perception. From single cells to system integration: it is this development the present Research Topic wishes to highlight and promote. How does this development affect our views on the various attributes of perception? In particular, we are interested in to what extent evolving knowledge in the field of color perception is relevant within a developing integrative framework of form perception. The goal of this Research Topic is to bring together experimental research encompassing both color and form perception. For this volume, we planned a broad scope of topics – on color in complex scenes, color and form, as well as dynamic aspects of form perception. We expect that the Research Topic will be attractive to the community of researchers whose work straddles the boundary between the two visual perception fields, as well as to the wider community interested in integrative/systems neuroscience.

The Adaptive Brain, II: Vision, Speech, Language, and Motor Control focuses on a unified theoretical analysis and predictions of important psychological and neurological data that illustrate the development of a true theory of mind and brain. The publication first elaborates on the quantized geometry of visual space and neural dynamics of form perception. Discussions focus on reflectance rivalry and spatial frequency detection, figure-ground separation by filling-in barriers, and disinhibitory propagation of functional scaling from boundaries to interiors. The text then takes a look at neural dynamics of perceptual grouping and brightness perception. Topics include simulation of a parametric binocular brightness study, smoothly varying luminance contours versus steps of luminance change, macrocircuit of processing stages, paradoxical percepts as probes of adaptive processes, and analysis of the Beck theory of textural segmentation. The book examines the neural dynamics of speech and language coding and word recognition and recall, including automatic activation and limited-capacity attention, a macrocircuit for the self-organization of recognition and recall, role of intra-list restructuring arid contextual associations, and temporal order information across item representations. The manuscript is a vital source of data for scientists and researchers interested in the development of a true theory of mind and brain.
