Active Inference


Book Description

The first comprehensive treatment of active inference, an integrative perspective on brain, cognition, and behavior used across multiple disciplines. Active inference is a way of understanding sentient behavior—a theory that characterizes perception, planning, and action in terms of probabilistic inference. Developed by theoretical neuroscientist Karl Friston over years of groundbreaking research, active inference provides an integrated perspective on brain, cognition, and behavior that is increasingly used across multiple disciplines including neuroscience, psychology, and philosophy. Active inference puts the action into perception. This book offers the first comprehensive treatment of active inference, covering theory, applications, and cognitive domains. Active inference is a “first principles” approach to understanding behavior and the brain, framed in terms of a single imperative to minimize free energy. The book emphasizes the implications of the free energy principle for understanding how the brain works. It first introduces active inference both conceptually and formally, contextualizing it within current theories of cognition. It then provides specific examples of computational models that use active inference to explain such cognitive phenomena as perception, attention, memory, and planning.




Dynamic Functional Connectivity in Neuropsychiatric Disorders: Methods and Applications, volume II


Book Description

Neuropsychiatric disorders have a huge impact on individuals, families and societies. However, the neuropathology underlying cognitive deficits in neuropsychiatric disorders remains unclear. Resting-state functional connectivity provides a powerful way to investigate functional alterations underlying cognitive deficits in neuropsychiatric disorders. Traditional FC analysis measures the correlations of signals with an assumption that functional connectivity remains constant during the observation period. In recent years, several studies have demonstrated the feasibility of dynamic methods in characterization of functional brain changes, such as dynamic functional connectivity investigated by a sliding window method. However, selection of window size, window stepsize and window type are open areas of research and an important parameter to capture the resting-state FC dynamics.




Principles of Brain Dynamics


Book Description

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.




Chromatin and Disease


Book Description

This book includes a collection of articles with the broad theme of disease connection to chromatin structure and function. It elaborates on the molecular pharmacology of the drugs targeting chromatin structure and its components. The book contains up-to-date information about the chromatin structure and chromatin related diseases and drug functions. This work is the first endeavor to present different aspects encompassing the above theme.

A Modal Approach to the Space-Time Dynamics of Cognitive Biomarkers


Book Description

This book develops and details a rigorous, canonical modeling approach for analyzing spatio-temporal brain wave dynamics. The nonlinear, nonstationary behavior of brain wave measures and general uncertainty associated with the brain makes it difficult to apply modern system identification techniques to such systems. While there is a substantial amount of literature on the use of stationary analyses for brain waves, relatively less work has considered real-time estimation and imaging of brain waves from noninvasive measurements. This book addresses the issue of modeling and imaging brain waves and biomarkers generally, treating the nonlinear and nonstationary dynamics in near real-time. Using a modal state-space formulation leads to intuitive, physically significant models which are used for analysis and diagnosis. A Modal Approach to the Space-Time Dynamics of Cognitive Biomarkers provides a much-needed reference for practicing researchers in biomarker modeling leveraging the lens of engineering dynamics.




Beyond the Brain


Book Description

Beyond the Brain seriously challenges the existing neurophysiological models of the brain. After three decades of extensive research on those non-ordinary states of consciousness induced by psychedelic drugs and by other means, Grof concludes that our present scientific world view is as inadequate as many of its historical predecessors. In this pioneering work, he proposes a new model of the human psyche that takes account of his findings. Grof includes in his model the recollective level, or the reliving of emotionally relevant memories, a level at which the Freudian framework can be useful. Beyond that is perinatal level in which the human unconscious may be activated to a reliving of biological birth and confrontation with death. How birth experience influences an individual's later development is a central focus of the book. The most serious challenge to contemporary psycho-analytic theory comes from a delineation of the transpersonal level, or the expansion of consciousness beyond the boundaries of time and space. Grof makes a bold argument that understanding of the perinatal and transpersonal levels changes much of how we view both mental illness and mental health. His reinterpretation of some of the most agonizing aspects of human behavior proves thought provoking for both laypersons and professional therapists.




2004 Rumelhart Prize Special Issue Honoring John R. Anderson


Book Description

This special issue of Cognitive Science honors the research and mentorship contributions of Dr. John R. Anderson, the 2004 David E. Rumelhart Prize recipient whose research has provided the field of cognitive psychology with comprehensive and integrative theories, and has had a practical impact on educational practice in the classroom and on student achievement in learning mathematics. The David E. Rumelhart Prize is awarded annually to an individual or collaborative team making a significant contemporary contribution to the formal analysis of human cognition. For three decades, Dr. Anderson has been engaged in a vigorous research program with the goal of developing a computational theory of mind. The diverse articles in this issue feature work by Dr. Anderson's students, colleagues, and collaborators, illustrating that it is possible to impact education with rigorous stimulation of human cognition.
