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.
Download or read book MEG written by Peter Hansen and published by Oxford University Press. This book was released on 2010-07-01 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetoencephalography (MEG) is an exciting brain imaging technology that allows real-time tracking of neural activity, making it an invaluable tool for advancing our understanding of brain function. In this comprehensive introduction to MEG, Peter Hansen, Morten Kringelbach, and Riitta Salmelin have brought together the leading researchers to provide the basic tools for planning and executing MEG experiments, as well as analyzing and interpreting the resulting data. Chapters on the basics describe the fundamentals of MEG and its instrumentation, and provide guidelines for designing experiments and performing successful measurements. Chapters on data analysis present it in detail, from general concepts and assumptions to analysis of evoked responses and oscillatory background activity. Chapters on solutions propose potential solutions to the inverse problem using techniques such as minimum norm estimates, spatial filters and beamformers. Chapters on combinations elucidate how MEG can be used to complement other neuroimaging techniques. Chapters on applications provide practical examples of how to use MEG to study sensory processing and cognitive tasks, and how MEG can be used in a clinical setting. These chapters form a complete basic reference source for those interested in exploring or already using MEG that will hopefully inspire them to try to develop new, exciting approaches to designing and analyzing their own studies. This book will be a valuable resource for researchers from diverse fields, including neuroimaging, cognitive neuroscience, medical imaging, computer modelling, as well as for clinical practitioners.

Download or read book Magnetoencephalography an emerging neuroimaging tool for studying normal and abnormal human brain development written by Christos Papadelis and published by Frontiers Media SA. This book was released on 2015-10-12 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on the human brain development has seen an upturn in the past years mostly due to novel neuroimaging tools that became available to study the anatomy and function of the developing brain. Magnetic Resonance Imaging (MRI) and Diffusion Tensor Imaging (DTI) are beginning to be used more frequently in children to determine the gross anatomy and structural connectivity of their brain. Functional MRI and Near-Infrared Spectroscopy (NIRS) determine the hemodynamics and electroencephalography (EEG) the electrophysiological functions of the developing human brain. Magnetoencephalography (MEG) complements EEG as the only other technique capable of directly measuring the developing brain electrophysiology. Although MEG is still being used relatively rarely in pediatric studies, the recent development in this technology is beginning to demonstrate its utility in both basic and clinical neurosciences. MEG seems to be quite attractive for pediatric use, since it measures the human brain activity in an entirely passive manner without possessing any conceivable risk to the developing tissue. MEG sessions generally require minimal patient preparation, and the recordings are extremely well tolerated from children. Biomagnetic techniques also offer an indirect way to assess the functional brain and heart activity of fetuses in humans in utero by measuring the magnetic field outside the maternal abdomen. Magnetic field produced by the electrical activity in the heart and brain of the fetus is not attenuated by the vernix, a waxy film covering its entire skin. A biomagnetic instrument specifically designed for fetal studies has been developed for this purpose. Fetal MEG studies using such a system have shown that both spontaneous brain activity and evoked cortical activity can be measured from outside the abdomen of pregnant mothers. Fetal MEG may become clinically very useful for implementation and evaluation of intervention programs in at-risk populations. Biomagnetic instruments have also been developed for specifically measuring the brain activity in newborns, infants and older children. MEG studies have shown the usefulness of MEG for localizing active regions in the brain and also for tracking the longitudinal maturation of various sensory systems. Studies of pediatric patients are beginning to show interesting functional pathology in autism spectrum disorder, cerebral palsy, epilepsy and other types of neurological and psychiatric disorders (Down syndrome, traumatic brain injury, Tourette syndrome, hearing deficits, childhood migraine). In this eBook, we compile the state of the art MEG and other neuroimaging studies focused on pediatric population in both health and disease. We believe a review of the recent studies of human brain development using MEG is quite timely, since we are witnessing advances not only in the instrumentation optimized for the pediatric population, but also in the research based on various types of MEG systems designed for both human fetuses in utero and neonates and older children.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work the response of the human brain to tactile finger stimulation was studied by means of magnetoencephalography (MEG). Spatio-temporal source imaging was applied to map the temporal evolution of activity in the primary (SI) and secondary (SII) somatosensory cortex with focus directed to SII. A method combining sequential dipole fitting and source seeding from standardized magnetic resonance images was developed for the analysis of data obtained from several subjects and applied in three different studies. First, a combined measurement of electroencephalogram (EEG) and MEG revealed two distinct generators of activity in the vicinity of SII. MEG was less contaminated with background brain activity and, therefore, proved more appropriate to image SII activity than EEG. In the second study, attention to stimulus location and intensity was shown to enhance SII activity around 80 ms by 52% and 64%, respectively. This effect was partly due to decelerated response decrement with persisting stimulation. The third study on simultanous stimulation of two fingers revealed significant suppressive interaction in SII of stimuli presented to one or two hands. During bilateral stimulation, both hemispheres appeared to specialize in the processing of the contralateral input and to suppress ipsilateral input.

Available in PDF, EPUB and Kindle. Book excerpt: "In the fifty years since magnetoencephalography (MEG) was invented, various clinical and research applications of it have been attempted with considerable success. This is most notable in the area of epilepsy and pre-surgical functioning mapping. However, the best way to apply MEG and interpret the findings still remains conjectural. As such, this book assesses the new clinical and research applications of MEG, especially for markers of neuropsychiatric and other disorders. It also evaluates the new instruments and analytic procedures that have been recently developed. Ultimately, the book may serve as a standard of clinical practice and as a source of ideas for expanding the applications of MEG"--
