Abstract

Functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) are noninvasive techniques used to measure neural activity in the human brain. fMRI measures the magnetic resonance signal associated with hemodynamic changes driven by neural activity and has a good spatial resolution (2–3 mm isotropic) and low temporal resolution (1–3 s). Whereas EEG is used to record electrical activity in the brain with a millisecond-level temporal resolution but has a limited spatial resolution. By combining fMRI and EEG, it is possible to generate a high spatiotemporal resolution map of human brain function, which is critical for understanding complex dynamics of the human brain. Furthermore, EEG recordings during fMRI can be used to identify the sources of abnormal electrical activity in the brain (e.g., during epileptic seizures). This chapter discusses recent advances in the simultaneous recording of fMRI and EEG in humans. It focuses on the challenges of recording fMRI and EEG simultaneously, techniques for removing artifacts, experimental designs for fMRI and EEG studies, and methods for integrating fMRI and EEG data.
