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.

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.

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.

EEG is a non-invasive technique that can measure brain activity. The neural activity generates electrical signals that are recorded by EEG electrodes placed on the scalp. When an individual is engaged in performing a cognitive task, brain activity changes and these changes can be recorded on the EEG graph. Therefore, it is a powerful tool for cognitive scientist aiming to better understand the neural correlates associated with different aspects of cognition, which will ultimately help them...
FAQs
Synchronization establishes a shared temporal reference for the two signal streams, allowing an EEG event to be related to a corresponding fMRI BOLD change. This matters because the measurements differ in temporal behavior: EEG captures rapid electrical fluctuations, whereas BOLD changes provide spatially resolved information. In behavioral experiments, alignment supports interpretation of when activity occurs and where it is associated.
MRI-related artifacts must be corrected before interpreting the EEG record. The scanning environment can introduce signals that are not part of the brain’s electrical activity, potentially obscuring millisecond-scale fluctuations. Artifact correction therefore protects the temporal information that makes EEG useful, while the fMRI stream retains its role in identifying spatially localized BOLD changes. Synchronization and correction are both necessary for meaningful integration.
EEG contributes precise information about the timing of neural electrical activity, while fMRI contributes detailed information about the location of associated blood-flow changes. Combining them helps researchers relate rapid events to their spatially distributed brain correlates rather than examining timing or location in isolation. This complementary view can support more complete models of brain function during behavior.
The combined recordings can be used to investigate attention, perception, learning, and decision-making by linking behavioral processes with both the timing and location of neural activity. This connection helps researchers examine how brain responses unfold during a task and where those responses are associated with BOLD changes, providing a multimodal basis for studying behavior.
Researchers must coordinate EEG recording, fMRI acquisition, signal synchronization, and correction of MRI-related artifacts. EEG electrodes collect the electrical signal while the scanner measures BOLD changes, but the resulting streams are useful together only when their timing is aligned and contamination in the EEG data is addressed. These coordinated steps produce data suitable for multimodal behavioral analysis.
These recordings can improve models of brain function by connecting fast neural events with spatially resolved brain responses. The approach also supports research on neurological and psychiatric conditions, where understanding both when activity occurs and where it is associated may be informative. Its value extends beyond a single task because the same logic applies across multiple forms of behavior.
