A classical view of neural computation is that it can be characterized in terms of convergence to attractor states or sequential transitions among states in a noisy background. After over three decades, is this still a valid model of how brain dynamics implements cognition? This book provides a comprehensive collection of recent theoretical and experimental contributions addressing the question of stable versus transient neural population dynamics from complementary angles. These studies showcase recent efforts for designing a framework that encompasses the multiple facets of metastability in neural responses, one of the most exciting topics currently in systems and computational neuroscience.

This book examines the psychology involved in handling, and responding to, materials in artistic practice, such as oils, charcoal, brushes, canvas, earth, and sand. Artists often work with intuitive, tactile sensations and rhythms that connect them to these materials. Rhythm connects the brain and body to the world, and the world of abstract art. The book features new readings of artworks by Matisse, Pollock, Dubuffet, Tápies, Benglis, Len Lye, Star Gossage, Shannon Novak, Simon Ingram, Lee Mingwei, L. N. Tallur and many others. Such art challenges centuries of philosophical and aesthetic order that has elevated the substance of mind over the substance of matter. This is a multidisciplinary study of different metastable patterns and rhythms: in art, the body, and the brain. This focus on the propagation of rhythm across domains represents a fresh art historical approach and provides important opportunities for art and science to cooperate.

Dance is a multi-sensory and multi-modal form of movement expression, one that stimulates creative potential for innovative action and intersubjective communication. Over the last two decades, results from systematic reviews have shown a spectrum of dance styles to be powerful, non-pharmacological agents in advancing intergenerational health across quality-of-life domains. This Research Topic invites further investigation into the specificity of how the dancing body can access untapped cognitive resources that promote brain health in the elderly. While early findings from dance protocols have been shown to impact positively on structural- and functional neuroplasticity, the link between embodied agency and brain health remains under-researched and under-theorized. Researchers are called to design methodologies that test the eco-validity of dance, explicitly examining the interactive effects of sentient expressive movement with cognitive reserve. One challenge, among many, lies in explicating and differentiating the elements of the dancing body itself, particularly when outcomes correlate with other forms of movement-rich exercise for the elderly.

Non-linear, or chaotic behaviour in real world systems has been reported in electronic circuits and communications systems, chemical reactions, biological behaviour. Applications include solitons, integrable systems, cellular automata, pattern formation, qualitative structure and bifurcation theory, onset of chaos and turbulence, analytic dynamics, and transport phenomena. This book presents important new research in this dynamic field.

How the ubiquitous human tendency to polarize--either or, nature nurture, body mind, yin yang--can be explained in terms of coordination dynamics, a new conception of brain function, and how such polar opposites can be reconciled.

How is free will possible in the light of the physical and chemical underpinnings of brain activity and recent neurobiological experiments? How can the emergence of complexity in hierarchical systems such as the brain, based at the lower levels in physical interactions, lead to something like genuine free will? The nature of our understanding of free will in the light of present-day neuroscience is becoming increasingly important because of remarkable discoveries on the topic being made by neuroscientists at the present time, on the one hand, and its crucial importance for the way we view ourselves as human beings, on the other. A key tool in understanding how free will may arise in this context is the idea of downward causation in complex systems, happening coterminously with bottom up causation, to form an integral whole. Top-down causation is usually neglected, and is therefore emphasized in the other part of the book’s title. The concept is explored in depth, as are the ethical and legal implications of our understanding of free will. This book arises out of a workshop held in California in April of 2007, which was chaired by Dr. Christof Koch. It was unusual in terms of the breadth of people involved: they included physicists, neuroscientists, psychiatrists, philosophers, and theologians. This enabled the meeting, and hence the resulting book, to attain a rather broader perspective on the issue than is often attained at academic symposia. The book includes contributions by Sarah-Jayne Blakemore, George F. R. Ellis , Christopher D. Frith, Mark Hallett, David Hodgson, Owen D. Jones, Alicia Juarrero, J. A. Scott Kelso, Christof Koch, Hans Küng, Hakwan C. Lau, Dean Mobbs, Nancey Murphy, William Newsome, Timothy O’Connor, Sean A.. Spence, and Evan Thompson.

Experimental evidence in humans and other mammalians indicates that complex neurodynamics is crucial for the emergence of higher-level intelligence. Dynamical neural systems with encoding in limit cycle and non-convergent attractors have gained increasing popularity in the past decade. The role of synchronization, desynchronization, and intermittent synchronization on cognition has been studied extensively by various authors, in particular by authors contributing to the present volume. This book addresses dynamical aspects of brain functions and cognition.

Experimental and theoretical approaches to global brain dynamics that draw on the latest research in the field. The consideration of time or dynamics is fundamental for all aspects of mental activity—perception, cognition, and emotion—because the main feature of brain activity is the continuous change of the underlying brain states even in a constant environment. The application of nonlinear dynamics to the study of brain activity began to flourish in the 1990s when combined with empirical observations from modern morphological and physiological observations. This book offers perspectives on brain dynamics that draw on the latest advances in research in the field. It includes contributions from both theoreticians and experimentalists, offering an eclectic treatment of fundamental issues. Topics addressed range from experimental and computational approaches to transient brain dynamics to the free-energy principle as a global brain theory. The book concludes with a short but rigorous guide to modern nonlinear dynamics and their application to neural dynamics.

Complex systems in nature are those with many interacting parts, all capable of influencing global system outcomes. There is a growing body of research that has modeled sport performance from a complexity sciences perspective, studying the behavior of individual athletes and sports teams as emergent phenomena which self-organise under interacting constraints. This book is the first to bring together experts studying complex systems in the context of sport from across the world to collate core theoretical ideas, current methodologies and existing data into one comprehensive resource. It offers new methods of analysis for investigating representative complex sport movements and actions at an individual and team level, exploring the application of methodologies from the complexity sciences in the context of sports performance and the organization of sport practice. Complex Systems in Sport is important reading for any advanced student or researcher working in sport and exercise science, sports coaching, kinesiology or human movement.
