This book was released on 2012-12-06 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cortical evoked potentials are of interest primarily as tests of changing neuronal excitabilities accompanying normal brain function. The first three steps in the anal ysis of these complex waveforms are proper placement of electrodes for recording, the proper choice of electrical or sensory stimulus parameters, and the establish ment of behavioral control. The fourth is development of techniques for reliable measurement. Measurement consists of comparison of an unknown entity with a set of standard scales or dimensions having numerical attributes in preassigned degree. A physical object can be described by the dimensions of size, mass, density, etc. In addition there are dimensions such as location, velocity, weight, hardness, etc. Some of these dimensions can be complex (e. g. size depends on three or more subsidiary coordi nates), and some can be interdependent or nonorthogonal (e. g. specification of size and mass may determine density). In each dimension the unit is defined with refer ence to a standard physical entity, e. g. a unit of mass or length, and the result of measurement is expressed as an equivalence between the unknown and the sum of a specified number of units of that entity. The dimensions of a complex waveform are elementary waveforms from which that waveform can be built by simple addition. Any finite single-valued function of time is admissible. They are called basis functions (lO, 15), and they can be expressed in numeric as well as geometric form.
Download or read book How Brains Make Up Their Minds written by Walter J. Freeman and published by Columbia University Press. This book was released on 2000 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: I think, therefore I am. The legendary pronouncement of philosopher René Descartes lingers as accepted wisdom in the Western world nearly four centuries after its author's death. But does thought really come first? Who actually runs the show: we, our thoughts, or the neurons firing within our brains? Walter J. Freeman explores how we control our behavior and make sense of the world around us. Avoiding determinism both in sociobiology, which proposes that persons' genes control their brains' functioning, and in neuroscience, which posits that their brains' disposition is molded by chemistry and environmental forces, Freeman charts a new course--one that gives individuals due credit and responsibility for their actions. Drawing upon his five decades of research in neuroscience, Freeman utilizes the latest advances in his field as well as perspectives from disciplines as diverse as mathematics, psychology, and philosophy to explicate how different human brains act in their chosen diverse ways. He clarifies the implications of brain imaging, by which neural activity can be observed during the course of normal movements, and shows how nonlinear dynamics reveals order within the fecund chaos of brain function.
Download or read book Brain Dynamics written by Erol Başar and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is based on contributions to the second Brain Dynamics Conference, held in Berlin on August 10-14, 1987, as a satellite conference of the Budapest Congress of the International Brain Research Organization. Like the volume resulting from the first conference, Dynamics of Sensory and Cognitive Processing by the Brain, the present work covers new approaches to brain function, with emphasis on electromagnetic fields, EEG, event-related potentials, connectivistic views, and neural networks. Close attention is also paid to research in the emerging field of deterministic chaos and strange attractors. The diversity of this collection of papers reflects a multipronged advance in a hitherto relatively neglected domain, i. e., the study of signs of dynamic processes in organized neural tissue in order both to explain them and to exploit them for clues to system function. The need is greater than ever for new windows. This volume reflects a historical moment, the moment when a relatively neglected field of basic research into available signs of dynamic processes ongoing in organized neural tissue is expanding almost explosively to complement other approaches. From the topics treated, this book should appeal, as did its predecessor, to neuroscientists, neurologists, scientists studying complex systems, artificial intelligence, and neural networks, psychobiologists, and all basic and clinical investigators concerned with new techniques of monitoring and analyzing the brain's electromagnetic activity.

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.
Download or read book Global Perspectives in Professional Reasoning written by Marilyn B. Cole and published by Taylor & Francis. This book was released on 2024-06-01 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global Perspectives in Professional Reasoning is the first text of its kind to address the broader scope of occupational therapy practice and the different types of professional reasoning that can be employed, including strategic, political, nonlinear, creative, and social reasoning. This text encompasses a wide range of thinking skills and cognitive processes used by occupational therapists, from reflecting on practice to solving problems, and from reasoning in the clinic to reasoning in the wider political, social, and cultural worlds. Marilyn B. Cole and Jennifer Creek and their contributors are therapists, educators, and scholars who have explored new areas of professional practice and written about the thought processes that reinforced their actions. The authors come from around the world, providing a global perspective while also demonstrating that occupational therapists within different cultures serve remarkably similar human needs: to be included in their communities, to have occupational choices, and to determine their own life course. Many of the contributors in Global Perspectives in Professional Reasoning have identified and analyzed their own thought processes as they tackled complex and challenging tasks, often in unfamiliar contexts. These challenging tasks have produced several entirely original conceptualizations of professional reasoning, such as development and spiritual reasoning. The contributors start by observing what is going on, try to make sense of the situation, and then work out what to do. Other contributors are fascinated by a theory, a policy, or an approach; study it; and then look for ways to utilize it in practice. Most of the time, contributors focus their attention on the process of reasoning rather than on the specific types of reasoning they are employing or on desired outcomes. Inside Global Perspectives in Professional Reasoning, each chapter charts the learning process that contributors went through as they extended their thinking skills and processes to meet the challenges they encountered. All the chapters describe reasoning in practice and all of them utilize theory. A broad and fresh take on professional reasoning in occupational therapy practice, Global Perspectives in Professional Reasoning is the perfect resource for occupational therapy students and clinicians who want to utilize reasoning to tackle the most complex and challenging of tasks.

Download or read book The Dynamic Brain written by Mingzhou Ding, PhD and published by Oxford University Press. This book was released on 2011-01-18 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: It is a well-known fact of neurophysiology that neuronal responses to identically presented stimuli are extremely variable. This variability has in the past often been regarded as "noise." At the single neuron level, interspike interval (ISI) histograms constructed during either spontaneous or stimulus evoked activity reveal a Poisson type distribution. These observations have been taken as evidence that neurons are intrinsically "noisy" in their firing properties. In fact, the use of averaging techniques, like post-stimulus time histograms (PSTH) or event-related potentials (ERPs) have largely been justified based on the presence of what was believed to be noise in the neuronal responses. More recent attempts to measure the information content of single neuron spike trains have revealed that a surprising amount of information can be coded in spike trains even in the presence of trial-to-trial variability. Multiple single unit recording experiments have suggested that variability formerly attributed to noise in single cell recordings may instead simply reflect system-wide changes in cellular response properties. These observations raise the possibility that, at least at the level of neuronal coding, the variability seen in single neuron responses may not simply reflect an underlying noisy process. They further raise the very distinct possibility that noise may in fact contain real, meaningful information which is available for the nervous system in information processing. To understand how neurons work in concert to bring about coherent behavior and its breakdown in disease, neuroscientists now routinely record simultaneously from hundreds of different neurons and from different brain areas, and then attempt to evaluate the network activities by computing various interdependence measures, including cross correlation, phase synchronization and spectral coherence. This book examines neuronal variability from theoretical, experimental and clinical perspectives.

Download or read book Micro Meso and Macro Dynamics of the Brain written by György Buzsáki and published by Springer. This book was released on 2016-05-02 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together leading investigators who represent various aspects of brain dynamics with the goal of presenting state-of-the-art current progress and address future developments. The individual chapters cover several fascinating facets of contemporary neuroscience from elementary computation of neurons, mesoscopic network oscillations, internally generated assembly sequences in the service of cognition, large-scale neuronal interactions within and across systems, the impact of sleep on cognition, memory, motor-sensory integration, spatial navigation, large-scale computation and consciousness. Each of these topics require appropriate levels of analyses with sufficiently high temporal and spatial resolution of neuronal activity in both local and global networks, supplemented by models and theories to explain how different levels of brain dynamics interact with each other and how the failure of such interactions results in neurologic and mental disease. While such complex questions cannot be answered exhaustively by a dozen or so chapters, this volume offers a nice synthesis of current thinking and work-in-progress on micro-, meso- and macro- dynamics of the brain.

Download or read book The Neurodynamic Soul written by Grant Gillett and published by Springer Nature. This book was released on 2023-12-19 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an analysis and discussion of the soul as a psychophysical process and its role in mental representation, meaning, understanding and agency. Grant Gillett and Walter Glannon combine contemporary neuroscience and philosophy to address fundamental issues about human existence and living and acting in the world. Based in part on Aristotle's hylomorphism and model of the psyche, their approach is informed by a neuroscientific model of the brain as a dynamic organ in which patterns of neural oscillation and synchronization are shaped by biological, social and cultural factors inside and outside of it. The authors provide a richer and more robust account of the soul, or mind, than other accounts by framing it in neuroscientific and philosophical terms that do not explain it away but explain it as something that is shaped by how it responds to the natural and social environment in enabling flexible and adaptive behavior.
Download or read book Free Will written by Uri Maoz and published by Oxford University Press. This book was released on 2022 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: "What is free will? Can it exist in a determined universe? How can we determine who, if anyone, possesses it? Philosophers have been debating these questions for millennia. In recent decades neuroscientists have joined the fray with questions of their own. Which neural mechanisms could enable conscious control of action? What are intentional actions? Do contemporary developments in neuroscience rule out free will or, instead, illuminate how it works? Over the past few years, neuroscientists and philosophers have increasingly come to understand that both fields can make substantive contributions to the free-will debate, so working together is the best path forward to understanding whether, when, and how our choices might be free. We therefore asked leading philosophers and neuroscientists which questions related to free will they would most like the other field to answer. Those experts then voted on the 15 most important questions for each field to answer. This book is a collection of the answers to those questions along with follow-up questions from world experts in the neuroscience and philosophy of free will. These varied perspectives will fascinate, illuminate, and stimulate students from both fields along with anyone who wants to be brought up to date on these profound issues"--

Download or read book Micro Meso Macro written by Hans Liljenstrm and published by World Scientific. This book was released on 2005 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the domain of science concerned with systems structure and behavior, the issue of the relationship between the micro and the macro level is of key importance. This book concentrates on the interplay between these levels and has a special focus on the level ?in between? ? the meso level.An investigation of those links is made through a number of cases from different domains of science, including physics, chemistry, ecology, social science, economics and technology. What is evident is that there are facets regarding meso-level issues that are similar between cases, but also that the domains differ in various ways. This is particularly exemplified by the differences in perspectives from which the natural and social sciences deal with scaling issues. The various examples provided in this book mirror its overriding theme: systems complexity.
Download or read book Imaging Brain Function With EEG written by Walter Freeman and published by Springer Science & Business Media. This book was released on 2012-10-28 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scalp and cortex lie like pages of an open book on which the cortex enciphers vast quantities of information and knowledge. They are recorded and analyzed as temporal and spatial patterns in the electroencephalogram and electrocorticogram. This book describes basic tools and concepts needed to measure and decipher the patterns extracted from the EEG and ECoG. This book emphasizes the need for single trial analysis using new methods and paradigms, as well as large, high-density spatial arrays of electrodes for pattern sampling. The deciphered patterns reveal neural mechanisms by which brains process sensory information into precepts and concepts. It describes the brain as a thermodynamic system that uses chemical energy to construct knowledge. The results are intended for use in the search for the neural correlates of intention, attention, perception and learning; in the design of human brain-computer interfaces enabling mental control of machines; and in exploring and explaining the physicochemical foundation of biological intelligence.
