A unified treatment of the generation and analysis of brain-generated electromagnetic fields. In Brain Signals, Risto Ilmoniemi and Jukka Sarvas present the basic physical and mathematical principles of magnetoencephalography (MEG) and electroencephalography (EEG), describing what kind of information is available in the neuroelectromagnetic field and how the measured MEG and EEG signals can be analyzed. Unlike most previous works on these topics, which have been collections of writings by different authors using different conventions, this book presents the material in a unified manner, providing the reader with a thorough understanding of basic principles and a firm basis for analyzing data...
Covers the diagnostic and clinical applications of transcranial magnetic stimulation (TMS) and offers cutting-edge, in-depth guidance on the use of TMS to study brain physiology and pathophysiology as well as its current and future therapeutic uses. Readers will find the essential up-to-date information they need to make the most of this dynamic method. Delivers a detailed analysis of the physics of magnetic stimulation as well as basic mechanisms of how magnetic stimulation activates neural tissue. Presents expert guidance on the clinical uses of TMS as well as its therapeutic and research applications.
There is a perceived tension between empirical and theoretical approaches to the study of language. Many recent works in the discipline emphasise that linguistics is an 'empirical science'. This volume argues for a nuanced view, highlighting that theory and practice necessarily and as a matter of fact complement each other in linguistic research. Its contributions ranging from experimental studies in psychology via linguistic fieldwork and cross-linguistic comparisons to the application of formal and logical approaches to language exemplify the mutual relationship between empirical and theoretical work. The volume illustrates how selected topics are addressed by different contributions and methodological stances. Topics include the cognitive grounding of language, social cognition and the construction of meaning in interaction, and, closely related, pragmatics from a typological perspective and beyond. Anyone interested in these topics and more generally in meta-theoretical considerations will find great value in this volume.
Recent concerns over the possible hazards of electrical and magnetic fields in the home and workplace are comprehensively addressed within this book. The chapters contain detailed research on the biological effects of electric and magnetic fields, and evidence for and against any interaction of electromagnetic fields (EMFs) and the biological systems. - The relative risk of exposure to EMFs - Putative behavioral and neural effects of EMFs - EMF effects on cells
The 1987 landmark publications by G. Lakoff and M. Johnson made image schema one of the cornerstone concepts of the emerging experientialist paradigm of Cognitive Linguistics, a framework founded upon the rejection of the mind-body dichotomy and stressing the fundamentally embodied nature of meaning, imagination and reason - hence language. Conceived of as the pre-linguistic, dynamic and highly schematic gestalts arising directly from motor movement, object manipulation, and perceptual interaction, image schemas served to anchor abstract reasoning and imagination to sensori-motor patterns in the conceptual theory of metaphor. Being itself informed by preceding crosslinguistic work on semanti...
Transcranial stimulation encompasses noninvasive methods that transmit physical fields-such as magnetic, electric, ultrasound, and light-to the brain to modulate its function. The most widespread approach, transcranial magnetic stimulation (TMS), has emerged as an important tool in several areas of neuroscience as well as in clinical applications in psychiatry and neurology. Originally envisioned as a way to measure the responsiveness and conduction speed of neurons and synapses in the brain and spinal cord, TMS has also become an important tool for changing the activity of brain neurons and the functions they subserve as well as an causal adjunct to brain imaging and mapping techniques. Alo...
Magnetoencephalography (MEG) is an invaluable functional brain imaging technique that provides direct, real-time monitoring of neuronal activity necessary for gaining insight into dynamic cortical networks. Our intentions with this book are to cover the richness and transdisciplinary nature of the MEG field, make it more accessible to newcomers and experienced researchers and to stimulate growth in the MEG area. The book presents a comprehensive overview of MEG basics and the latest developments in methodological, empirical and clinical research, directed toward master and doctoral students, as well as researchers. There are three levels of contributions: 1) tutorials on instrumentation, mea...
Fifty Years of Magnetoencephalography celebrates the discovery and evolution of the newest method for imaging the activity of the human brain--magnetoencephalography, or MEG. This volume reveals the degree to which particular brain areas, revealed through MEG, contribute to different behavioral and psychological functions like sensation, motor behavior, and language. It also details current clinical applications of this technology in epilepsy surgery and indicates what the future applications are most likely to be.
With a foreword by well-known neuroscientist Alain Berthoz, The Style of Gestures convincingly makes the case that embodied cognition is essential to the reception, understanding, and enjoyment of art and literature.
The global spread of science and technology expertise and the growing commercial access to advanced technologies with possible military application are creating potentially serious threats to the technological superiority underpinning U.S. military strength. Key to dealing with this situation is the ability of the U.S. intelligence community to be able to provide adequate and effective warning of evolving, critical technologies. To assist in performing this task, the Technology Warning Division of the Defense Intelligence Agency (DIA) asked the National Research Council (NRC) to undertake a study examining technology warning issues. This report provides the first part of that study. It presents an assessment of critical, evolving technologies; postulates ways potential adversaries could disrupt these technologies; and provides indicators for the intelligence community to determine if such methods are under development. The intention of this report is to establish the foundation for a long-term relationship with the technology warning community to support the examination of technology warning issues.
