The purpose of this study was to develop a method for obtaining simultaneous electrophysiological and functional magnetic resonance imaging data. Using phantom experiments and tests on several of the investigators, a method for obtaining simultaneous electrophysiological and fMRI data was developed and then tested in three volunteers including two task activation experiments. It was then applied in a sleep experiment (n = 12). Current limiting resistance and low‐pass filtering were added to the… 
Real-time artifact filtering in continuous VEPs/fMRI recording
Recording of the event‐related potentials during functional MRI at 3.0 Tesla field strength
TLDR
The feasibility of recording event‐related potentials (ERP) during functional MRI (fMRI) scanning was studied using an alternating checkerboard stimulus in a blocked presentation and artifacts overlaid on the electrophysiological recordings were corrected by post hoc filtering methods presented here.

TLDR
By merging these two recording methods, it is likely that the authors will gain a more detailed understanding of not only the areas involved in certain physiologic events, e.g. focal epilepsy or cognitive processing, but also on the sequencing of the activation of the various participating regions.
Acquiring simultaneous EEG and functional MRI
EEG recording during fMRI experiments: Image quality
TLDR
It was concluded that concurrent EEG and fMRI could be performed without compromising the image quality significantly if suitable equipment is used and the image noise originating from the EEG recording equipment was identified as coherent noise and could be eliminated by appropriate shielding of the EEG equipment.
Simultaneous Electromyography and Functional Magnetic Resonance Imaging of Skeletal Muscle
TLDR
The proposed method combines both techniques in simultaneous data acquisition to provide greater muscle physiological information during exercise, and both techniques are non-invasive making repeated measurements feasible.
Physical modeling of pulse artefact sources in simultaneous EEG/fMRI
TLDR
Of these two sources, head rotation was shown to be the most likely source of the PA with simulated magnitudes being generated at 3 T, similar to the in vivo PA magnitudes, for an angular velocity of just 0.5°/s.

Adaptation of activity in human auditory cortex was shown to reveal long-term features with a paradigm that compared response amplitudes for three tones randomly presented, showing the locations of neuronal sources for different tone frequencies could be obtained without moving the recording instrument.
Processing strategies for time‐course data sets in functional mri of the human brain
TLDR
The most effective method for image processing involves thresholding by shape as characterized by the correlation coefficient of the data with respect to a reference waveform followed by formation of a cross‐correlation image.
