Book Synopsis Adaptive Spatial Filters for Electromagnetic Brain Imaging by : Kensuke Sekihara
Download or read book Adaptive Spatial Filters for Electromagnetic Brain Imaging written by Kensuke Sekihara and published by Springer. This book was released on 2008-06-06 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neural activity in the human brain generates coherent synaptic and intracellular currents in cortical columns that create electromagnetic signals which can be measured outside the head using magnetoencephalography (MEG) and electroencephalography (EEG). Electromagnetic brain imaging refers to techniques that reconstruct neural activity from MEG and EEG signals. Electromagnetic brain imaging is unique among functional imaging techniques for its ability to provide spatio-temporal brain activation profiles that reflect not only where the activity occurs in the brain but also when this activity occurs in relation to external and internal cognitive events, as well as to activity in other brain regions. Adaptive spatial filters are powerful algorithms for electromagnetic brain imaging that enable high-fidelity reconstruction of neuronal activity. This book describes the technical advances of adaptive spatial filters for electromagnetic brain imaging by integrating and synthesizing available information and describes various factors that affect its performance. The intended audience include graduate students and researchers interested in the methodological aspects of electromagnetic brain imaging.

Book Synopsis Magnetic Source Imaging of the Human Brain by : Zhong-Lin Lu
Download or read book Magnetic Source Imaging of the Human Brain written by Zhong-Lin Lu and published by Psychology Press. This book was released on 2003-10-17 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is designed to acquaint serious students, scientists, and clinicians with magnetic source imaging (MSI)--a brain imaging technique of proven importance that promises even more important advances. The technique permits spatial resolution of neural events on a scale measured in millimeters and temporal resolution measured in milliseconds. Although widely mentioned in literature dealing with cognitive neuroscience and functional brain imaging, there is no single book describing both the foundations and actual methods of magnetoencephalopgraphy and its underlying science, neuromagnetism. This volume fills a long-standing need, as it is accessible to scientists and students having no special background in the field, and makes it possible for them to understand this literature and undertake their own research. A self-contained unit, this book covers MSI from beginning to end, including its relationship to allied technologies, such as electroencephalography and modern functional imaging modalities. In addition, the book: *introduces the field to the non-specialist, providing a framework for the rest of the book; *provides a thorough review of the physiological basis of MSI; *describes the mathematical bases of MSI--the forward and inverse problems; *outlines new signal processing methods that extract information from single-trial MEG; *depicts the early, as well as the most recent versions of MSI technology; *compares MSI with other imaging methodologies; *describes new paradigms and analysis techniques in applying MSI to study human perception and cognition, which are also applicable to EEG; and *reviews some of the most important results in MSI from the most prominent researchers and laboratories around the world.
Book Synopsis Electromagnetics in Magnetic Resonance Imaging by : Christopher M. Collins
Download or read book Electromagnetics in Magnetic Resonance Imaging written by Christopher M. Collins and published by Morgan & Claypool Publishers. This book was released on 2016-03-01 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past few decades, Magnetic Resonance Imaging (MRI) has become an indispensable tool in modern medicine, with MRI systems now available at every major hospital in the developed world. But for all its utility and prevalence, it is much less commonly understood and less readily explained than other common medical imaging techniques. Unlike optical, ultrasonic, X-ray (including CT), and nuclear medicine-based imaging, MRI does not rely primarily on simple transmission and/or reflection of energy, and the highest achievable resolution in MRI is orders of magnitude smaller that the smallest wavelength involved. In this book, MRI will be explained with emphasis on the magnetic fields required, their generation, their concomitant electric fields, the various interactions of all these fields with the subject being imaged, and the implications of these interactions to image quality and patient safety. Classical electromagnetics will be used to describe aspects from the fundamental phenomenon of nuclear precession through signal detection and MRI safety. Simple explanations and Illustrations combined with pertinent equations are designed to help the reader rapidly gain a fundamental understanding and an appreciation of this technology as it is used today, as well as ongoing advances that will increase its value in the future. Numerous references are included to facilitate further study with an emphasis on areas most directly related to electromagnetics.

Book Synopsis Electromagnetic Inverse Applications for Functional Brain Imaging by :
Download or read book Electromagnetic Inverse Applications for Functional Brain Imaging written by and published by . This book was released on 1997 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the final report of a one-year, Laboratory Directed Research and Development (LDRD) project at Los Alamos National Laboratory (LANL). This project addresses an important mathematical and computational problem in functional brain imaging, namely the electromagnetic {open_quotes}inverse problem.{close_quotes} Electromagnetic brain imaging techniques, magnetoencephalography (MEG) and electroencephalography (EEG), are based on measurements of electrical potentials and magnetic fields at hundreds of locations outside the human head. The inverse problem is the estimation of the locations, magnitudes, and time-sources of electrical currents in the brain from surface measurements. This project extends recent progress on the inverse problem by combining the use of anatomical constraints derived from magnetic resonance imaging (MRI) with Bayesian and other novel algorithmic approaches. The results suggest that we can achieve significant improvements in the accuracy and robustness of inverse solutions by these two approaches.

Download or read book Brain Stimulation written by Ji Hyun Ko and published by Elsevier Inc. Chapters. This book was released on 2013-11-11 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of functional brain imaging techniques, including positron emission tomography (PET), single-photon emission computed tomography (SPECT), and functional magnetic resonance imaging (fMRI), has allowed for monitoring neuronal and neurochemical activities in the living human brain and identifying abnormal changes in various neurological and psychiatric diseases. Combining these methods with techniques such as deep brain stimulation (DBS) and transcranial magnetic stimulation (TMS) has greatly advanced our understanding of the effects of such treatment on brain activity at targeted regions as well as specific disease-related networks. Indeed, recent network-level analysis focusing on inter-regional covarying activities in data interpretation has unveiled several key mechanisms underlying the therapeutic effects of brain stimulation. However, non-negligible discrepancies have been reported in the literature, attributable in part to the heterogeneity of both imaging and brain stimulation techniques. This chapter summarizes recent studies that combine brain imaging and brain stimulation, and includes discussion of future direction in these lines of research.
Book Synopsis Electroconvulsive and Neuromodulation Therapies by : Conrad M. Swartz
Download or read book Electroconvulsive and Neuromodulation Therapies written by Conrad M. Swartz and published by Cambridge University Press. This book was released on 2009-03-02 with total page 619 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electroconvulsive therapy (ECT) is a psychiatric treatment involving the induction of a seizure through the transmission of electricity in the brain. Because of exploitation movies and greatly heightened drug company promotional activities ECT was used less frequently in the 1980s and 1990s. Eventually these movies were understood as unrealistic. Now these drugs are increasingly recognized as dangers to body health. Because of recent refinements and a far better scientific understanding of the clinical procedures and mechanisms underpinning ECT, this treatment modality has seen a resurgence in use and widespread appreciation of its safety. This book is the new definitive reference on electroconvulsive and neuromodulation therapies. It comprehensively covers the scientific basis and clinical practice of ECT as well as comparisons between ECT and medication therapies including the new generation of antipsychotic drugs. It also provides readers with administrative perspectives and specific details for the management of this modality in clinical practice. The new forms of nonconvulsive electrical and magnetic brain stimulation therapy are also covered in detail, in a separate section. The chapter authors are leading scholars and clinicians.

Download or read book Looking Inside the Brain written by Denis Le Bihan and published by Princeton University Press. This book was released on 2014-11-30 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: The remarkable story of how today's brain scanning techniques were developed, told by one of the field's pioneers It is now possible to witness human brain activity while we are talking, reading, or thinking, thanks to revolutionary neuroimaging techniques like magnetic resonance imaging (MRI). These groundbreaking advances have opened infinite fields of investigation—into such areas as musical perception, brain development in utero, and faulty brain connections leading to psychiatric disorders—and have raised unprecedented ethical issues. In Looking Inside the Brain, one of the leading pioneers of the field, Denis Le Bihan, offers an engaging account of the sophisticated interdisciplinary research in physics, neuroscience, and medicine that have led to the remarkable neuroimaging methods that give us a detailed look into the human brain. Introducing neurological anatomy and physiology, Le Bihan walks readers through the historical evolution of imaging technology—from the x-ray and CT scan to the PET scan and MRI—and he explains how neuroimaging uncovers afflictions like stroke or cancer and the workings of higher-order brain activities, such as language skills. Le Bihan also takes readers on a behind-the-scenes journey through NeuroSpin, his state-of-the-art neuroimaging laboratory, and goes over the cutting-edge scanning devices currently being developed. Considering what we see when we look at brain images, Le Bihan weighs what might be revealed about our thoughts and unconscious, and discusses how far this technology might go in the future. Beautifully illustrated in color, Looking Inside the Brain presents the trailblazing story of the scanning techniques that provide keys to previously unimagined knowledge of our brains and our selves.
