EEG + fNIRS

This multimodal approach combines EEG's excellent temporal resolution for measuring electrical brain activity with functional Near-Infrared Spectroscopy (fNIRS), which measures changes in brain oxygenation (hemodynamic response). By combining these two, researchers gain a more complete picture of brain function, simultaneously capturing both neural electrical activity and the metabolic demands associated with it. A special feature of this integration is its ability to overcome the limitations of each modality individually, providing complementary information with good spatial resolution from fNIRS and excellent temporal resolution from EEG, particularly useful for studying brain activity in more natural, mobile environments.

  • Complementary Information: Combines electrical activity (EEG) with hemodynamic responses (fNIRS) for a comprehensive view of brain function.
  • Improved Spatial Resolution (fNIRS): Offers better localization of activity than standalone EEG.
  • Portability & Mobility (fNIRS): Can be used in more naturalistic and active settings than fMRI.
  • Overcomes Modality Limitations: Addresses the spatial limitations of EEG and the temporal limitations of fNIRS when used separately.
