MEG-EEG Primer presents the basic A-to-Z of two non-invasive human electrophysiological methods, magnetoencephalography (MEG) and electroencephalography (EEG). These methods are used to study human brain dynamics, tracking the brain's responses to sensory, cognitive, and social stimuli. This book, now in its second edition, remains the only volume of its kind that discusses both MEG and EEG side-by-side, for an integrated understanding of brain function. In 22 chapters with almost two hundred color figures, the book covers the basic physical and physiological foundations of these two methods, the historical background and development of their implementation, instrumentation, recording techniques, data analysis, and interpretation.
