Explore cortical haemodynamics with a setup designed for your regions of interest, participants and recording conditions.
Gaze Intelligence supports cortical coverage, optode setup, signal quality and acquisition planning. We also assess combinations with EEG, eye tracking and other physiological measurements.
Synchronisation, markers and export formats are part of protocol preparation. Describe regions of interest, population and movement constraints to discuss the required setup and support.
Let's discuss your fNIRS project →fNIRS uses light sources and detectors on the scalp. Absorption changes estimate oxygenated (HbO) and deoxygenated (HbR) haemoglobin concentration changes. This haemodynamic measurement is indirectly related to neural activity; it is not electrical recording.
The setup determines sampled areas. Optical contact, hair, movement and superficial physiology affect data. Theoretical channel count alone cannot compare configurations.
MOBILITYPortable platform with Aurora fNIRS acquisition. The manufacturer describes 8- or 16-source configurations, detector options, USB or Wi-Fi and standalone recording. Options depend on the chosen configuration.

MODULARITYModular platform to adapt coverage and optical options. Dedicated setups may combine EEG, TMS or MRI. Required equipment must be defined for each modality.

fNIRS AND fMRIA fibre-optic configuration for fNIRS in MRI, associated with NIRSport2. Accessories and installation conditions are integral to the project.
Discuss a Borealis configuration with Gaze Intelligence →Screen studies, motor tasks and interpersonal interactions have different equipment needs. For movement, we assess mounting, freedom of movement and quality monitoring. Hyperscanning also requires participant and event synchronisation planning.
The research platforms shown here are not offered as diagnostic tools. In combined projects, compatibility must cover the whole configuration, not just the amplifier.
NIRSport2 documentation mentions SNIRF and NIRS and synchronisation via LSL or trigger input. Aurora handles acquisition; Satori and Turbo-Satori serve different analysis uses depending on licences and needs.
We suggest checking a sample file in your analysis pipeline before deployment. Keep setup, events and settings too: a readable file may still be hard to interpret without them. Compare fNIRS and EEG. Prepare multimodal acquisition.
