What is a common non-invasive technology used alongside MEG to gain complementary data?

Electroencephalography (EEG) is a common non-invasive technology used alongside Magnetoencephalography (MEG) to gather complementary data due to its ability to record electrical activity in the brain over time. MEG measures the magnetic fields produced by neuronal activity, providing precise spatial resolution, while EEG offers excellent temporal resolution by capturing rapid changes in electrical activity.

The combination of MEG and EEG allows researchers and clinicians to obtain a comprehensive view of brain function, where MEG provides detailed information about the localization of brain activity and EEG captures the timing and dynamics of electrical events. This synergy is particularly valuable in clinical contexts, such as pre-surgical mapping for epilepsy or brain tumors, where understanding both the spatial and temporal aspects of brain activity is crucial for effective intervention.

Other imaging modalities, while valuable in their own right, serve different purposes and do not provide the same complementary benefits in terms of direct measurement of brain activity alongside MEG.
