Book Description
Rapid corrective actions, termed automatic postural responses, are essential to counter the destabilizing effect of mechanical perturbations during natural behaviors. Previous research has demonstrated that automatic postural responses of the limbs and body share a number of capabilities in adapting to the prevailing circumstances and these abilities reflect contributions from multiple supraspinal pathways, including brainstem nuclei, basal ganglia, and primary motor cortex. However, we do not know the context-dependent contribution from specific generators, whether different neural pathways have a common role across different effectors, and how sensory and central deficits in one pathway are accommodated by those remaining. Bridging these gaps is essential to integrate the diverse set of studies, develop general theories of motor control, and explicate how the nervous system addresses the partially distinct behavioral demands of co-evolved effector system. The considerable flexibility and multiple interacting pathways of automatic postural responses also make it ideal for understanding how powerful formal theories, like optimal feedback control, are achieved by a distributed hierarchical neural network.

Book Description
Neuromechanics of Human Movement, Fifth Edition, draws on the disciplines of neurophysiology and physics to explore how the nervous system controls the actions of muscles to produce human motion. This contemporary approach is much different from the traditional approach, which focuses solely on mechanics and does not consider the role of the sensorimotor system in the control of human movement. Authored by Roger Enoka, a widely recognized and esteemed scholar in neuromechanics, this influential text is an essential resource in biomechanics, motor learning, and applied physiology, making complex information accessible to students. With material based on updated research in the field, this fifth edition provides a scientific foundation to the study of human movement, and as such it uses precise terms and definitions when discussing ideas. An appendix showcases both the base and derived units of the metric system as well as other learning tools, including a glossary of terms and a comprehensive list of the equations presented throughout the text. The text includes 70 practical learning examples, giving students the opportunity to work through a variety of problems and explore current research and applications. Content is visually reinforced with 341 figures, including specific illustrations of the neuromechanics involved in sport and rehabilitation movements. References have been streamlined and moved to the end of each chapter to improve readability. And instructors will benefit from an image bank that includes most of the figures and tables from the text to use in course materials. Significant content updates in the fifth edition present information relevant for both research and clinical environments, including more contemporary examples throughout the text and a new chapter on movement analysis. The following are additional key changes: • New figures that highlight and clarify key points • New information on energy costs • Debunking the concept of motor unit types • Detailed information on the center of mass trajectory • Explanation of neuromodulation • Additional content on PET imaging to help examine activity intensity To encourage a comprehensive learning experience, this updated edition follows a logical progression where each part builds on the material from the previous section. It begins with an introduction to the biomechanical terms and concepts commonly used to describe movement, focusing on the relation between force and motion. Part II deals with the motor system and introduces essential concepts from neurophysiology required for understanding how movement is produced by the nervous system. Part III focuses on adaptability of the motor system, including the acute and chronic changes that can occur in response to deviations in an individual’s level of physical activity. The fifth edition of Neuromechanics of Human Movement provides a scientific basis for the study of human movement while continuing to expand current knowledge in the fields of biomechanics and neurophysiology. By integrating these fields in a unique framework, this text offers professionals and students both valuable clinical information and inspiration to deepen their study of human movement.

Book Description
Studies of human movement have proliferated in recent years, and there have been many studies of spinal pathways in humans, their role in movement, and their dysfunction in neurological disorders. This comprehensive reference surveys the literature related to the control of spinal cord circuits in human subjects, showing how they can be studied, their role in normal movement, and how they malfunction in disease states. Chapters are highly illustrated and consistently organised, reviewing, for each pathway, the experimental background, methodology, organisation and control, role during motor tasks, and changes in patients with CNS lesions. Each chapter concludes with a helpful resume that can be used independently of the main text to provide practical guidance for clinical studies. This will be essential reading for research workers and clinicians involved in the study, treatment and rehabilitation of movement disorders.

Book Description
Recent advances in motor behavior research rely on detailed knowledge of the characteristics of the neurons and networks that generate motor behavior. At the cellular level, Neurons, Networks, and Motor Behavior describes the computational characteristics of individual neurons and how these characteristics are modified by neuromodulators. At the network and behavioral levels, the volume discusses how network structure is dynamically modulated to produce adaptive behavior. Comparisons of model systems throughout the animal kingdom provide insights into general principles of motor control. Contributors describe how networks generate such motor behaviors as walking, swimming, flying, scratching, reaching, breathing, feeding, and chewing. An emerging principle of organization is that nervous systems are remarkably efficient in constructing neural networks that control multiple tasks and dynamically adapt to change.The volume contains six sections: selection and initiation of motor patterns; generation and formation of motor patterns: cellular and systems properties; generation and formation of motor patterns: computational approaches; modulation and reconfiguration; short-term modulation of pattern generating circuits; and sensory modification of motor output to control whole body orientation.

Book Description
Recently, studies on aging processes and age-related changes in behavior have been expanding considerably, probably due to the dramatic changes observed in the demographics. This increase in the overall age and proportion of elderly people has heightened the severity of problems associated with the safety and well-being of elderly persons in everyday life. Many researchers working on motor control have thus focused more intensely on the effects of age on motor control. This new avenue of research has led to programs for alleviating or delaying the specific sensory-motor limitations encountered by the elderly (e.g. falls) in an attempt to make the elderly more autonomous.The aggregation of studies from different perspectives is often fascinating, especially when the same field can serve as a common ground between researchers. Nearly all contributors to this book work on sensory-motor aging; they represent a large range of affiliations and backgrounds including psychology, neurobiology, cognitive sciences, kinesiology, neuropsychology, neuropharmacology, motor performance, physical therapy, exercise science, and human development. Addressing age-related behavioral changes can also furnish some crucial reflections in the debate about motor coordination: aging is the product of both maturational and environmental processes, and studies on aging must determine how the intricate interrelationships between these processes evolve. The study of aging makes it possible to determine how compensatory mechanisms, operating on different subsystems and each aging at its own rate, compensate for biological degenerations and changing external demands. This volume will contribute to demonstrating that the study of the aging process raises important theoretical questions.

Book Description
Computational Intelligence (CI) is a recently emerging area in fundamental and applied research, exploiting a number of advanced information processing technologies that mainly embody neural networks, fuzzy logic and evolutionary computation. With a major concern to exploiting the tolerance for imperfection, uncertainty, and partial truth to achieve tractability, robustness and low solution cost, it becomes evident that composing methods of CI should be working concurrently rather than separately. It is this conviction that research on the synergism of CI paradigms has experienced significant growth in the last decade with some areas nearing maturity while many others remaining unresolved. This book systematically summarizes the latest findings and sheds light on the respective fields that might lead to future breakthroughs.
