Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that has shown initial therapeutic effects in several neurological conditions. The main mechanism underlying these therapeutic effects is the modulation of cortical excitability. Therefore, online monitoring of cortical excitability would help guide stimulation parameters and optimize its therapeutic effects. In the present article we review the use of a novel device that combines simultaneous tDCS and...

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.

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...

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.
FAQs
The two techniques provide complementary information within the same session. EEG tracks neural activity as it unfolds, while tDCS modifies cortical excitability during that period. Comparing EEG responses across stimulation conditions can show whether tDCS changes oscillations or event-related signals, helping researchers connect stimulation-related neural changes with concurrent behavioral effects.
This approach can assess changes in brain oscillations and event-related signals, which are neural responses associated with particular events or task moments. Examining both types of activity helps distinguish ongoing changes in brain dynamics from responses linked to attention, learning, decision-making, or motor control. The resulting measures can clarify how stimulation relates to behavior.
Because stimulation is delivered while neural activity and behavior are examined, researchers can test whether altering cortical excitability changes a measured brain signal and a behavioral function at the same time. This design goes beyond observing correlations alone, supporting more direct evaluation of whether neural activity contributes to attention, learning, decision-making, or motor control.
EEG alone measures electrical brain activity without applying stimulation, whereas tDCS alone modulates cortical excitability without simultaneously tracking neural responses. Combining them links the intervention to immediate neural measurements within one session. That integration helps researchers evaluate how stimulation changes brain signals and whether those changes correspond to behavioral outcomes.
Researchers record EEG while applying tDCS through scalp electrodes, allowing neural responses to be monitored during stimulation rather than only before or afterward. They can then examine oscillations, event-related signals, and behavioral measures collected in the same experimental context. This workflow connects the stimulation condition, brain response, and observed task performance.
The method is valuable when a study asks how modulating cortical excitability affects a measurable behavior and the neural activity associated with it. Applications include investigations of attention, learning, decision-making, and motor control. Findings can also guide the development and refinement of noninvasive neuromodulation protocols by relating stimulation effects to neural and behavioral outcomes.
