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...

Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation technique. It has successfully been used in basic research and clinical settings to modulate brain function in humans. This article describes the implementation of tDCS and simultaneous functional magnetic resonance imaging (fMRI), to investigate the neural basis of tDCS effects.
FAQs
The approach aligns changes in cortical excitability with performance during an active task rather than examining neural modulation in isolation. Because participants respond to visual, motor, or cognitive events while stimulation occurs, researchers can investigate how altered cortical state interacts with behavior. This design is especially relevant when the goal is to connect neural effects with task performance.
Applying stimulation at the same time as the interactive activity creates a shared experimental period in which neural modulation and task engagement occur together. This temporal pairing allows researchers to examine their interaction under controlled conditions. It also supports studies that ask whether a changed cortical state is associated with performance during motor learning or cognitive activity.
The VR environment can present visual, motor, or cognitive activities, giving the method a broader task range than a single fixed behavioral paradigm. Researchers may therefore examine motor learning, cognitive performance, or neurorehabilitation-related behavior. The selected activity determines which behavioral responses can be studied while cortical excitability is being altered.
VR provides an immersive, interactive environment that can represent experiences with greater ecological relevance than a purely abstract task, while still allowing the activity to be repeated in a controlled way. This combination helps researchers study behavior in meaningful task settings without giving up experimental consistency across participants or sessions.
A session pairs scalp electrodes delivering low-amplitude direct current with a selected VR activity, and the participant performs that activity while stimulation is applied. The essential procedural feature is synchronization: stimulation and task engagement occupy the same application period. Researchers can then examine behavioral responses in relation to the concurrent neural modulation and task demands.
Researchers would choose the combined approach when they need to examine neural modulation during an interactive, task-based experience. It is suited to questions about how altered cortical excitability relates to motor learning, cognitive performance, or neurorehabilitation activities. Studying both elements together preserves the controlled stimulation component while adding a repeatable and ecologically relevant behavioral context.
