Both methods are totally noninvasive and can track with millisecond temporal resolution spontaneous brain activity, evoked responses to various sensory stimuli, as well as signals associated with the performance of motor, cognitive and affective tasks.MEG records the magnetic fields, and EEG the potentials associated with the same neuronal currents, which however are differentially weighted due to the physical and physiological differences between the methods. MEG is rather selective to activity in the walls of cortical folds, whereas EEG senses currents from the cortex (and brain) more widely, making it harder to pinpoint the locations of the source currents in the brain. Another important difference between the methods is that skull and scalp dampen and smear EEG signals, but do not affect MEG. Hence, to fully understand brain function, \u003cbr\u003e\u003cbr\u003e\u003cb\u003eTrade Review\u003c\/b\u003e\u003cbr\u003eThis Primer fulfills a gap in the human neurophysiology literature where no book exists dealing with MEG and EEG in equal terms. This is important since both methodologies are, in essence, complementary and jointly can be used to answer specific scientific questions with respect to a variety of brain functions. Special attention is paid to comparisons of findings obtained using both MEG and EEG modalities, what can yield important new insights, particularly in the growing field of cognitive neuroscience. Written in an appealing style, this Primer embraces the whole field of human neurophysiology.\" -Fernando Lopes Da Silva, MD, PhD, Emeritus Professor, Center of Neuroscience, Swammerdam Institute for Life Sciences, Amsterdam, The Netherlands\u003cbr\u003e\u003cbr\u003e\u003cb\u003eTable of Contents\u003c\/b\u003e\u003cbr\u003ePREFACE   PREAMBLE   SECTION 1 CHAPTER 1: INTRODUCTION  MEG and EEG Setups  Comparison of MEG and EEG  Structure of this Primer   CHAPTER 2: INSIGHTS INTO THE HUMAN BRAIN  Overview of the Human Brain  How to Obtain Information About Brain Function  Timing in Human Behavior  Functional Structure of the Human Cerebral Cortex  Communication Between Brain Areas  Thalamocortical Connections  Intra-Brain Connectivity  Electric Signaling in Neurons  Membrane Potential  Action Potentials  Postsynaptic Potentials   CHAPTER 3: BASIC PHYSICS AND PHYSIOLOGY OF MEG AND EEG  An Overview of MEG and EEG Signal Generation  Charges and Electric Current  Ohm's and Kirchoff's Laws  Relationship Between Current and Magnetic Field  Superconductivity  Inverse Problem  Source Currents  Primary Current  Layers, Open Fields, and Closed Fields  Intracortical Cancellation  Volume Conduction  Spherical Head Model  Some General Points About Source Localization   CHAPTER 4: AN OVERVIEW OF EEG AND MEG  Historical Aspects  Early EEG Recordings  Early MEG Recordings  Brain Rhythms  Evoked and Event-Related Responses   SECTION 2 CHAPTER 5: INSTRUMENTATION FOR MEG AND EEG  EEG Instrumentation  Electrodes  EEG Amplifiers  Differential Amplifiers, Common Mode Rejection, and Amplifier Input Impedances  Standard Electrode Positions  Effects of Reference Electrode on Potential Distribution  Re-Referencing Relative to an Average Reference  MEG Instrumentation  Squids and Squid Electronics  Flux Transformers and Their Configuration  Shielding  Other Means to Maintain a Noise-Free Environment  Stimulators and Monitoring Devices  Auditory Stimulators  Visual Stimulators  Somatosensory Stimulators  Stimulators for Inducing Acute Pain  Passive-Movement Stimulators (Proprioception Stimulation)  Monitoring Devices  Future Developments of EEG and MEG Instrumentation  Developments in EEG  Developments in MEG  CHAPTER 6.
