Event-related functional magnetic resonance imaging

Event-related functional magnetic resonance imaging

Event-related functional magnetic resonance imaging (efMRI) is a form of functional Magnetic Resonance Imaging (fMRI) in which a series of fMRI images are time-locked to a stimulus presentation and averaged together. The relationship of the technique to fMRI is analogous to the relationship between ERP (Event-Related Potential) data and EEG (Electroencephalogram) data. Some have suggested using this technique in conjunction with ERP measurements to localize the structural origins of an ERP wave.
