fNIRS EEG features
The combination of EEG and NIRS offers complementary information about brain function, giving you the ability to measure both neural and hemodynamic activity simultaneously.
intergrated fnirs eeg holderWith our new NIRS-EEG packages, we went one step further than other companies in this market: we truly integrated the optode holders and EEG holders into one holder as well as the software. In this way, we can provide full head coverage, and all data is integrated and synchronized within our proprietary recording software, OxySoft. This enables you to conveniently measure EEG and NIRS with automatic event synchronization.
MobilityOur wearable NIRS-EEG packages provide the perfect solution for any lab experiment where subject mobility is needed. They also let you measure real-world behavior like walking, biking, driving a car, and more.
Our packages are also ideal for on-site measurements outside of the lab environment since the equipment fits in a small backpack and can easily be brought to a school, a workplace, the home of an immobile individual, or any other place you can think of.
Software OxySoft, our proprietary recording software has native support for the TMSi SAGA device and can record EEG data from the Neuroelectrics devices received via the Lab Streaming Layer. In this way, all data is conveniently integrated and synchronized within OxySoft with automatic event synchronization.
OxySoft is able to analyze your data or export it to a wide variety of toolboxes (e.g. HOMER2/3, NIRS-SPM, Fieldtrip, EEGLAB, Brainstorm/NIRSTORM).

Why combine fNIRS and EEG?
The combination of EEG and NIRS gives you the ability to measure both neural and hemodynamic activity simultaneously, providing complementary information about brain function.
EEG measures the electromagnetic field created when neurons in the brain fire. With fNIRS, you measure the hemodynamic response, which is the adjustment of oxygen in the blood when a brain region is active. By combining EEG and fNIRS, you are provided with a complete picture of brain activity: activation of neurons and energy demand of neurons. Moreover, EEG and NIRS have complementary spatial and temporal resolution. While EEG is a spatially imprecise recording technique due to volume conduction, meaning that even activation several centimeters away is recorded by electrodes, NIRS measures very precisely right under the location of the sensors.
Despite the spatial imprecision, EEG is a very useful technique as it records at a very high sample rate of up to several Kilohertz and can detect rapidly changing brain processes. The hemodynamic response is a slower response, taking a few seconds to initiate and then smearing out over several seconds. Combining EEG and NIRS, therefore, makes it possible to monitor the brain at multiple timescales, various spatial resolutions, and through distinct underlying physiological processes.

When simultaneously measuring fNIRS and EEG, placement of both devices should ideally ensure proper coverage of the desired measurement location, minimize interference and take into account (technical) characteristics and basic of both techniques. Read this blog post to learn more about relevance of these points and further recommendations for integrating fNIRS and EEG on one head.
