This paper describes a method for collecting and analyzing electroencephalography (EEG) data during concurrent transcranial magnetic stimulation (TMS) guided by activations revealed with functional magnetic resonance imaging (fMRI). A method for TMS artifact removal and extraction of event related potentials is described as well as considerations in paradigm design and experimental setup.

Simultaneous electroencephalography (EEG) and functional Magnetic Resonance imaging (fMRI) is a powerful neuroimaging tool. However, the inside of an MRI scanner forms a difficult environment for EEG data recording and safety must be considered whenever operating EEG equipment inside a scanner. Here, we present an optimised EEG-fMRI data acquisition protocol.

Neurophysiology is broadly defined as the study of nervous system function. In this field, scientists investigate the central and peripheral nervous systems at the level of whole organs, cellular networks, single cells, or even subcellular compartments. A unifying feature of this wide-ranging discipline is an interest in the mechanisms that lead to the generation and propagation of electrical impulses within and between neurons. This subject is important not only for our understanding of the...

Method for Simultaneous fMRI/EEG Data Collection during a Focused Attention Suggestion for Differential Thermal Sensation

We present a protocol for concurrent collection of EEG/fMRI data, and synchronized MR clock signal recording. We demonstrate this method using a unique paradigm whereby subjects receive ‘cold glove’ instructions during scanning, and EEG/fMRI data are recorded along with hand temperature measurements both before and after hypnotic induction.

Synchronization establishes temporal correspondence between the two measurements. EEG events can be aligned with slower fMRI blood-oxygenation changes, allowing investigators to examine which brain regions and networks are engaged when a transient neural event occurs. This alignment supports interpretation of the modalities as complementary measurements during behaviorally relevant tasks or periods of rest.
The combination addresses different measurement strengths. EEG distinguishes rapid changes in neural activity, whereas fMRI identifies the spatial distribution of associated brain responses. Considering both dimensions can show how quickly neural events unfold and where distributed systems are involved, producing a more comprehensive account of behavioral processes than either recording approach can provide independently.
The fMRI signal supplies spatial and network-level context for activity that EEG captures primarily through its rapid timing. Relating a transient EEG event to blood-oxygenation changes helps researchers determine which regions or distributed networks accompany that event. This connection is especially useful when studying how localized and widespread brain systems contribute to behavior.
These recordings can support studies of attention, perception, learning, and decision-making, as well as investigations of brain states during tasks or rest. By relating transient neural events to hemodynamic responses, researchers can examine how distributed neural systems accompany behavior across different experimental contexts in a unified analysis.
A typical study acquires EEG and fMRI simultaneously while participants perform a behavioral task or remain at rest. The EEG record supplies the timing of neural events, while the fMRI record identifies associated blood-oxygenation changes across regions and networks. Researchers then relate the two signals to the task or behavioral context to interpret coordinated brain activity.
The recordings can reveal relationships between moment-to-moment neural dynamics and the brain regions or networks associated with them. In behavioral research, this may clarify how distributed systems support attention, perception, learning, decision-making, or resting brain states. The resulting interpretation links observed behavior with both the timing and spatial organization of neural activity.
