With the rise of cognitive science and the revolution in neuroscience, it is now commonplace to assume that the study of a human person—a thinking, feeling, acting subject—is ultimately the study of the human brain. In both Europe and the United States, massive state-funded research is focused on mapping the brain in all its remarkable complexity. The metaphors employed are largely technological: A wiring diagram of synaptic connectivity will lead to a better understanding of human behavior and perhaps insights into the breakdown of human personhood with diseases of the brain such as Alzheimer’s. Alongside this technologized discourse of the brain as locus of human subjectivity we find another perspective, one that emphasizes its essential plasticity—in both the developmental sense and as a response to traumas such as strokes, tumors, or gunshot wounds. This collection of essays brings together a diverse range of scholars to investigate how the “neural subject” of the twenty-first century came to be. Taking approaches both historical and theoretical, they probe the possibilities and limits of neuroscientific understandings of human experience. Topics include landmark studies in the history of neuroscience, the relationship between neural and technological “pathologies,” and analyses of contemporary concepts of plasticity and pathology in cognitive neuroscience. Central to the volume is a critical examination of the relationship between pathology and plasticity. Because pathology is often the occasion for neural reorganization and adaptation, it exists not in opposition to the brain’s “normal” operation but instead as something intimately connected to our ways of being and understanding.

The adult brain is not as hard-wired as traditionally thought. By modifying their small- or large-scale morphology, neurons can make new synaptic connections or break existing ones (structural plasticity). Structural changes accompany memory formation and learning, and are induced by neurogenesis, neurodegeneration and brain injury such as stroke. Exploring the role of structural plasticity in the brain can be greatly assisted by mathematical and computational models, as they enable us to bridge the gap between system-level dynamics and lower level cellular and molecular processes. However, most traditional neural network models have fixed neuronal morphologies and a static connectivity pattern, with plasticity merely arising from changes in the strength of existing synapses (synaptic plasticity). In The Rewiring Brain, the editors bring together for the first time contemporary modeling studies that investigate the implications of structural plasticity for brain function and pathology. Starting with an experimental background on structural plasticity in the adult brain, the book covers computational studies on homeostatic structural plasticity, the impact of structural plasticity on cognition and cortical connectivity, the interaction between synaptic and structural plasticity, neurogenesis-related structural plasticity, and structural plasticity in neurological disorders. Structural plasticity adds a whole new dimension to brain plasticity, and The Rewiring Brain shows how computational approaches may help to gain a better understanding of the full adaptive potential of the adult brain. The book is written for both computational and experimental neuroscientists. - Reviews the current state of knowledge of structural plasticity in the adult brain - Gives a comprehensive overview of computational studies on structural plasticity - Provides insights into the potential driving forces of structural plasticity and the functional implications of structural plasticity for learning and memory - Serves as inspiration for developing novel treatment strategies for stimulating functional repair after brain damage

Brain Oscillations, Synchrony and Plasticity: Basic Principles and Application to Auditory-Related Disorders discusses the role of brain oscillations, especially with respect to the auditory system and how those oscillations are measured, change over the lifespan, and falter leading to a variety of psychiatric and neurological disorders. The book begins with a description of these cortical rhythm oscillations and how they function in both the normal and pathological brain. It explains how these oscillations are important to auditory, executive and attention brain networks and how they relate to the development, production and deterioration of speech and language. In addition, treatment of malfunctioning cortical rhythms are reviewed using neuromodulation, such as transcranial magnetic, direct current, random noise, and alternating current stimulation, as well as focused ultrasound. The book concludes by describing the potential role of oscillations in dyslexia, autism, schizophrenia and Alzheimer's disease. - Introduces readers to brain imaging methods such as structural and functional magnetic resonance imaging, EEG and magnetoencephalography, in the study of brain oscillations, synchrony and networks of the normal and pathological brain - Highlights the role of brain oscillations in perception and cognition, in particular with respect to the auditory system, speech and language - Describes lifespan changes, from preterm to senescence, of brain oscillations, brain networks and how they relate to the development and deterioration of speech and language - Explains the effects of hearing loss on neural network change in the auditory and non-auditory networks such as the default mode-, the salience-, the executive- and attention networks - Illustrates the breakdown of network connections in auditory-related disorders such as tinnitus and in psychiatric disorders with a strong auditory, speech and language component

Catastrophic scenarios dominate our contemporary mindset. Catastrophic events and predictions have spurred new interest in re-examining the history of earlier disasters and the social and conceptual resources they have mobilized. The essays gathered in this volume reconsider the history and theory of different catastrophes and their aftermath. The emphasis is on the need to distance this process of reconsideration from previous teleological representations of catastrophes as an endpoint, and to begin considering their "operative" aspects, which unmask the nature of social and political structures. Among the essays in this volume are analyses, by leading scholars in their respective fields, concerning the role of catastrophes in theology, in the history of industrial accidents, in theory of history, in the history of law, in "catastrophe films", in the history of cybernetics, in post-Holocaust discussions of reparations, and in climate change.

The most recent high-profile advocate for Americans with disabilities, actor Christopher Reeve, has highlighted for the public the economic and social costs of disability and the importance of rehabilitation. Enabling America is a major analysis of the field of rehabilitation science and engineering. The book explains how to achieve recognition for this evolving field of study, how to set priorities, and how to improve the organization and administration of the numerous federal research programs in this area. The committee introduces the "enabling-disability process" model, which enhances the concepts of disability and rehabilitation, and reviews what is known and what research priorities are emerging in the areas of: Pathology and impairment, including differences between children and adults. Functional limitationsâ€"in a person's ability to eat or walk, for example. Disability as the interaction between a person's pathologies, impairments, and functional limitations and the surrounding physical and social environments. This landmark volume will be of special interest to anyone involved in rehabilitation science and engineering: federal policymakers, rehabilitation practitioners and administrators, researchers, and advocates for persons with disabilities.

Two leading neuroscientists examine the current paradigm of the “neural subject” and what we can learn from neurological trauma, pathology, and adaption. With the rise of cognitive science and the revolution in neuroscience, the study of human subjects—thinking, feeling, acting individuals—ultimately focuses on the human brain. In both Europe and the United States, massive state-funded research is focused on mapping the brain in all its remarkable complexity. The metaphors employed are largely technological, using a diagram of synaptic connectivity as a path to understanding human behavior. But alongside this technologized discourse, we find another perspective, one that emphasizes the brain’s essential plasticity, both in development and as a response to traumas such as strokes, tumors, or gunshot wounds. This collection of essays brings together a diverse range of scholars to investigate how the “neural subject” of the twenty-first century came to be. Taking approaches both historical and theoretical, they probe the possibilities and limits of neuroscientific understandings of human experience.

Central to the volume is a critical examination of the relationship between pathology and plasticity.
