Book Description
Functional magnetic resonance imaging (fMRI) and Electronecephalography (EEG) are very important and complementary modalities since fMRI offers high spatial resolution and EEG is a direct measurement of neuronal activity with high temporal resolution. Interest in the integration of both types of data is growing rapidly as it promises to provide important new insights into human brain activity as it has already done so in the field of epilepsy. The availability of good quality instrumentation capable of providing interference-free data in both modalities means that electrophysiological and haemodynamic characteristics of individual brain events can be captured for the first time. Consequently, it seems certain that the integration of fMRI and EEG will play an increasing role in neuroscience and of the clinical study of brain disorders such as epilepsy. The proposed book will discuss in detail the physiological principles, practical aspects of measurement, artefact reduction and analysis and also applications of the integration of fMRI and EEG. All applications, which are mainly in the fields of sleep research, cognitive neuroscience and clinical use in neurology and psychiatry will be reviewed.

Book Description
One of the major challenges in science is to study and understand the human brain. Numerous methods examining different aspects of brain functions have been developed and employed. To study systemic interactions brain networks in vivo, non-invasive methods such as electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) have been used with great success. However, each of these methods can map only certain, quite selective aspects of brain function while missing others; and the inferences on neuronal processes and information flow are often rather indirect. To overcome these shortcomings of single methods, researchers have attempted to combine methods in order to make optimal use of their advantages while compensating their disadvantages. Hence, it is not surprising that soon after the introduction of fMRI as a neuroimaging method the possibilities of combinations with EEG have been explored. This book is intended to aid researchers who plan to set up a simultaneous EEG-fMRI laboratory and those who are interested in integrating electrophysiological and hemodynamic data. As will be obvious from the different chapters, this is a dynamically developing field in which several approaches are being tested, validated and compared. Currently, there is no one best solution for all problems available, but many promising techniques are emerging. This book shall give a comprehensive overview of these techniques. In addition, it points to open questions and directions for future research.

Book Description
This book provides the most up-to-date and comprehensive source of information on all aspects of EEG-fMRI, a neuroimaging technique for synchronous acquisition of electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) data. The reader will find in-depth information on the physiological principles of the EEG and fMRI signals, practical aspects of data measurement, artifact reduction, data analysis, and applications. All the main areas of the technique’s application are the subject of one or multiple chapters: sleep research, cognitive neuroscience, and clinical neurology and psychiatry. In addition to providing a thorough update, this second edition offers five entirely new chapters covering important areas of research that have emerged during the past 5 years, including noninvasive brain stimulation during fMRI, resting-state functional connectivity, real-time fMRI, and neurofeedback. Written by the most prestigious experts in the field, the text is enhanced by numerous high-quality illustrations. This book will be valuable for neuroradiologists, neuroscientists, physicists, engineers, electrophysiologists, (neuro) medical scientists, neurologists, and neurophysiologists.

Book Description
Simultaneous acquisition of Electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) enables studying of brain function with high spatial resolution of fMRI and high temporal resolution of EEG. The complementary characteristics of the two modalities have made simultaneous EEG-fMRI into a rapidly growing neuroimaging technique with a wide range of cognitive and clinical applications. This thesis uses simultaneous EEG-fMRI to investigate the relationship between electrophysiological activity of the brain and the corresponding hemodynamic response during sensory processing of auditory and visual stimuli. Despite major improvements during the short history of EEG-fMRI, several technical and methodological challenges still remain. The main challenge in EEG-fMRI is the compromised EEG data quality. EEG data recorded inside the MR scanner is contaminated by artifacts caused by the MR magnetic fields. This thesis provides a comparative evaluation of the existing EEG artifact removal methods and proposes new analysis approaches to improve the EEG data quality. Another open question in the field of EEG-fMRI is the optimal choice of measures and techniques for data integration. This thesis proposes a new multivariate approach for EEG-fMRI data integration, which enables taking advantage of the full spectrum of the data available in two modalities. The proposed multivariate technique as well as conventional univariate methods are then used to explore the relationship between various aspects of the brainâ s electrophysiological activity (i.e. the transient evoked activity, oscillatory evoked activity and spontaneous oscillatory activity) and the associated hemodynamic response in auditory and visual cortices.

Book Description
Over the past two decades, fMRI has evolved into an invaluable clinical tool for routine brain imaging. This book provides a state of the art overview of fMRI and its use in clinical practice. Experts in the field share their knowledge and explain how to overcome diverse potential technical barriers and problems. Starting from the very basics on the origin of the BOLD signal, the book covers technical issues, anatomical landmarks, the full range of clinical applications, methods of statistical analysis, and special issues in various clinical fields. Comparisons are made with other brain mapping techniques, such as DTI, PET, TMS, EEG, and MEG, and their combined use with fMRI is also discussed. Since the first edition, original chapters have been updated and new chapters added, covering both novel aspects of analysis and further important clinical applications.

Book Description
The second, revised edition of this successful textbook provides an up-to-date description of the use of preoperative fMRI in patients with brain tumors and epilepsies. State of the art fMRI procedures are presented, with detailed consideration of practical aspects, imaging and data processing, normal and pathological findings, and diagnostic possibilities and limitations. Relevant information on brain physiology, functional neuroanatomy, imaging technique, and methodology is provided by recognized experts in these fields. Compared with the first edition, chapters have been updated to reflect the latest developments and in particular the current use of diffusion tensor imaging (DTI) and resting-state fMRI. Entirely new chapters are included on resting-state presurgical fMRI and the role of DTI and tractography in brain tumor surgery. Further chapters address multimodality functional neuroimaging, brain plasticity, and pitfalls, tips, and tricks.
