This book is a comprehensive overview of the main current concepts in brain cognitive activities at the global, collective (or network) level, with a focus on transitions between normal neurophysiology and brain pathological states. It provides a unique approach of linking molecular and cellular aspects of normal and pathological brain functioning with their corresponding network, collective and dynamical manifestations that are subsequently extended to behavioral manifestations of healthy and diseased brains. This book introduces a high-level perspective, searching for simplification amongst the structural and functional complexity of nervous systems by consideration of the distributed interactions that underlie the collective behavior of the system. The authors hope that this approach could promote a global comprehensive understanding of high-level laws behind the elementary biological processes in the neuroscientific community, while, perhaps, introducing elements of biological complexities to the mathematical/computational readership. The title of the book refers to the main point of the monograph: that there is a smooth continuum between distinct brain activities resulting in different behaviors, and that, due to the plastic nature of the brain, the behavior can also alter the brain function, thus rendering artificial the boundaries between the brain and its behavior.

Since 2003, when spontaneous activity in cortical slices was first found to follow scale-free statistical distributions in size and duration, increasing experimental evidences and theoretical models have been reported in the literature supporting the emergence of evidence of scale invariance in the cortex. Although strongly debated, such results refer to many different in vitro and in vivo preparations (awake monkeys, anesthetized rats and cats, in vitro slices and dissociated cultures), suggesting that power law distributions and scale free correlations are a very general and robust feature of cortical activity that has been conserved across species as specific substrate for information storage, transmission and processing. Equally important is that the features reminiscent of scale invariance and criticality are observed at scale spanning from the level of interacting arrays of neurons all the way up to correlations across the entire brain. Thus, if we accept that the brain operates near a critical point, little is known about the causes and/or consequences of a loss of criticality and its relation with brain diseases (e.g. epilepsy). The study of how pathogenetical mechanisms are related to the critical/non-critical behavior of neuronal networks would likely provide new insights into the cellular and synaptic determinants of the emergence of critical-like dynamics and structures in neural systems. At the same time, the relation between the impaired behavior and the disruption of criticality would help clarify its role in normal brain function. The main objective of this Research Topic is to investigate the emergence/disruption of the emergent critical-like states in healthy/impaired neural systems.

The aim of this Research Topic is to discuss the state of the art on the use of Information-based methods in the analysis of neuroimaging data. Information-based methods, typically built as extensions of the Shannon Entropy, are at the basis of model-free approaches which, being based on probability distributions rather than on specific expectations, can account for all possible non-linearities present in the data in a model-independent fashion. Mutual Information-like methods can also be applied on interacting dynamical variables described by time-series, thus addressing the uncertainty reduction (or information) in one variable by conditioning on another set of variables. In the last years, different Information-based methods have been shown to be flexible and powerful tools to analyze neuroimaging data, with a wide range of different methodologies, including formulations-based on bivariate vs multivariate representations, frequency vs time domains, etc. Apart from methodological issues, the information bit as a common unit represents a convenient way to open the road for comparison and integration between different measurements of neuroimaging data in three complementary contexts: Structural Connectivity, Dynamical (Functional and Effective) Connectivity, and Modelling of brain activity. Applications are ubiquitous, starting from resting state in healthy subjects to modulations of consciousness and other aspects of pathophysiology. Mutual Information-based methods have provided new insights about common-principles in brain organization, showing the existence of an active default network when the brain is at rest. It is not clear, however, how this default network is generated, the different modules are intra-interacting, or disappearing in the presence of stimulation. Some of these open-questions at the functional level might find their mechanisms on their structural correlates. A key question is the link between structure and function and the use of structural priors for the understanding of the functional connectivity measures. As effective connectivity is concerned, recently a common framework has been proposed for Transfer Entropy and Granger Causality, a well-established methodology originally based on autoregressive models. This framework can open the way to new theories and applications. This Research Topic brings together contributions from researchers from different backgrounds which are either developing new approaches, or applying existing methodologies to new data, and we hope it will set the basis for discussing the development and validation of new Information-based methodologies for the understanding of brain structure, function, and dynamics.

Many people spend considerable time seeking a sense of purpose in life and, concomitant with that, a sense of personal identity. This book demystifies this search, revealing why this search is a fallacy. The purpose is to inform readers about results in neuroscience and biophysics that may guide us to some liberation needed in the current age of great complexity in life with a diverse burden of chores; a deliverance from some afflictions that prevent individuals from achieving the true purpose of our lives. Among these afflictions we find two primordial concerns: the belief and subsequent attachment to a self, and the conviction that life must have a deep purpose in which we are major players. While this is a scientific text, it can easily be read by a lay audience, written with minimal technical jargon and with references to scientific papers enough to satisfy the curious. We have tried to extract the essence of scientific observations such that we can glimpse at those aforementioned concerns about the self and life, observations which help us comprehend what we are and what we become, the being and becoming of our own selves and natural phenomena around us. Jose Luis Perez Velazquez received a PhD in Molecular Physiology & Biophysics. His research seeks principles of biological organisation. He worked at the Hospital for Sick Children in Toronto and was Professor at the University of Toronto. Currently he is a Research Scholar at the Ronin Institute and lives in the natural paradise of Asturias, in Northern Spain. Vera Nenadovic is a nurse practitioner, neuroscientist and entrepreneur. She has 30 years of experience in healthcare from First Nations communities to intensive care units. Her research focuses on predicting brain injury outcomes. She is a clinician and researcher at Holland Bloorview Kids Rehab Hospital. Her startup company BrainsView is commercializing software that analyzes brainwaves to monitor brain function and recovery after head injury. She is married and lives in Toronto, with her husband and Rottweiler.

In addition to chemical links across synapses, neurons can also form direct connections via electrical gap junctions. These channels play a key role in brain development and intercellular communication. Dere (pathophysiology of cerebral aging, U. Pierre et Marie Curie, Paris; AP-HP Hôpital Charles Foix, Centre de Recherche et Développement, Ivry-sur-Seine, France) introduces types of gap junctions, their structural aspects, expression patterns of connexins (transmembrane proteins), and gap junction-related diseases due to mutations in connexin genes. International researchers working in this emerging field discuss specific connexin genes and their mechanisms of action and function in the developing neocortx, behavior, and neurological and neuropsychiatric diseases. The text includes color and b&w illustrations including schematic representations and models. Academic Press is an imprint of Elsevier. Annotation ©2013 Book News, Inc., Portland, OR (booknews.com).

National Book Award Finalist: “This man’s ideas may be the most influential, not to say controversial, of the second half of the twentieth century.”—Columbus Dispatch At the heart of this classic, seminal book is Julian Jaynes's still-controversial thesis that human consciousness did not begin far back in animal evolution but instead is a learned process that came about only three thousand years ago and is still developing. The implications of this revolutionary scientific paradigm extend into virtually every aspect of our psychology, our history and culture, our religion—and indeed our future. “Don’t be put off by the academic title of Julian Jaynes’s The Origin of Consciousness in the Breakdown of the Bicameral Mind. Its prose is always lucid and often lyrical…he unfolds his case with the utmost intellectual rigor.”—The New York Times “When Julian Jaynes . . . speculates that until late in the twentieth millennium BC men had no consciousness but were automatically obeying the voices of the gods, we are astounded but compelled to follow this remarkable thesis.”—John Updike, The New Yorker “He is as startling as Freud was in The Interpretation of Dreams, and Jaynes is equally as adept at forcing a new view of known human behavior.”—American Journal of Psychiatry

How do we understand mental health problems in their social context? A former BMA Medical Book of the Year award winner, this book provides a sociological analysis of major areas of mental health and illness. The book considers contemporary and historical aspects of sociology, social psychiatry, policy and therapeutic law to help students develop an in-depth and critical approach to this complex subject.New developments for the fifth edition include: Brand new chapter on prisons, criminal justice and mental health Expanded coverage of stigma, class and social networks Updated material on the Mental Capacity Act, Mental Health Act and the Deprivation of Liberty A classic in its field, this well established textbook offers a rich and well-crafted overview of mental health and illness unrivalled by competitors and is essential reading for students and professionals studying a range of medical sociology and health-related courses. It is also highly suitable for trainee mental health workers in the fields of social work, nursing, clinical psychology and psychiatry. "Rogers and Pilgrim go from strength to strength! This fifth edition of their classic text is not only a sociology but also a psychology, a philosophy, a history and a polity. It combines rigorous scholarship with radical argument to produce incisive perspectives on the major contemporary questions concerning mental health and illness. The authors admirably balance judicious presentation of the range of available understandings with clear articulation of their own positions on key issues. This book is essential reading for everyone involved in mental health work." Christopher Dowrick, Professor of Primary Medical Care, University of Liverpool, UK "Pilgrim and Rogers have for the last twenty years given us the key text in the sociology of mental health and illness. Each edition has captured the multi-layered and ever changing landscape of theory and practice around psychiatry and mental health, providing an essential tool for teachers and researchers, and much loved by students for the dexterity in combining scope and accessibility. This latest volume, with its focus on community mental health, user movements criminal justice and the need for inter-agency working, alongside the more classical sociological critiques around social theories and social inequalities, demonstrates more than ever that sociological perspectives are crucial in the understanding and explanation of mental and emotional healthcare and practice, hence its audience extends across the related disciplines to everyone who is involved in this highly controversial and socially relevant arena." Gillian Bendelow, School of Law Politics and Sociology, University of Sussex, UK "From the classic bedrock studies to contemporary sociological perspectives on the current controversy over which scientific organizations will define diagnosis, Rogers and Pilgrim provide a comprehensive, readable and elegant overview of how social factors shape the onset and response to mental health and mental illness. Their sociological vision embraces historical, professional and socio-cultural context and processes as they shape the lives of those in the community and those who provide care; the organizations mandated to deliver services and those that have ended up becoming unsuitable substitutes; and the successful and unsuccessful efforts to improve the lives through science, challenge and law." Bernice Pescosolido, Distinguished Professor of Sociology, Indiana University, USA

The field of psychiatry changed dramatically in the latter half of the nineteenth century, largely by embracing science. The transformation was most evident in Germany, where many psychiatrists began to work concurrently in the clinic and the laboratory. Some researchers sought to discover brain correlates of mental illness, while others looked to experimental psychology for insights into mental dynamics. Featured here, are the lives and works of Emil Kraepelin - often considered the founder of modern scientific psychiatry, his teacher Bernhard Gudden, and his anatomist colleague Franz Nissl. The book describes scientific findings together with the methods used; it explains why diagnoses were then (and are still now) so difficult to make; it also explores mind-brain controversies. The Making of Modern Psychiatry will inform and delight mental health professionals as well as all persons curious about the origins of modern psychiatry. ``Ronald Chase has provided fascinating information about the 19th century scientists' thinking on behavioral disorders: how to identify them, how to treat them, how to understand them ... He is a terrific writer and has compiled very interesting stories that bring to life the thinking of the time and the condition of serious mental illnesses in their first stages of understanding ... The author weaves the work of the 20th to 21st centuries nicely into his story ... gives optimism for a brain-based understanding in the future.''
