摘要: Publisher Summary This chapter discusses megnetocephalography and magnetic source imaging. Neuromagnetic recordings offer several advantages over alternative noninvasive imaging modalities. Magnetoencephalography (MEG), as with electroencephalography (EEG), provides for real-time, direct assessment of brain electrophysiology. MEG, therefore, an important complement to structural modalities such computed tomography (CT) resonance (MRI) hemodynamic metabolic techniques functional MRI (fMRI), positron emission (PET), single-photon (SPECT). MEG affords certain EEG. The most salient these is that neuromagnetic signals penetrate the skull scalp without significant distortion. spatial resolution higher than EEG, mathematical analyses pattern field can accurate localization neurons responsible generating signals. Of available neuroimaging techniques, best balance temporal sensitivity physiology.
