Magnetoencephalography (MEG) is a non-invasive procedure similar to EEG in terms of basic principles and analysis. Instead of scalp electrodes, MEG uses superconducting quantum interference devices (SQUIDs) as sensors to detect the magnetic field pattern produced by brain activity. Beamforming, source modeling and dipole techniques can be used to estimate and localize brain activity in 3D. Sspatial localization of current sources with whole head MEG is on the order of 2-3 mm at a temporal resolution better than 1 ms. MEG forms a complementary modality to fMRI that allows a more refined study of temporal dynamics and network interaction. The MEG Core operates a 275 channel MEG system that is state of the art for whole head MEG systems. The mission of the Core is to provide all necessary support for a PI to successfully design and implement an MEG based project. This will usually include detailed experimental design discussion, software and hardware design and testing, training in data collection and system instruction, and in signal processing and data analysis.
