Wireless data transfer allows participants to move freely while data is both stored on the device and streamed in real time. The NIRSport2 platform and the NIRxWINGS2 provide a combined LSL stream, ensuring seamless integration for multimodal research.

NIRxWINGS2 Advantages

The ideal in fNIRS research is that we measure only the evoked hemodynamic response. In reality, non-evoked, systemic activity is also present. To ensure we completely isolate the metabolic brain activity (i.e., HbO and HbR) due to the task we are interested in, we can measure peripheral physiological data (e.g., heart rate, respiration, tonic/phasic skin conductance, SpO₂). These additional signals help explain more variance in the fNIRS signal, improving research outcomes.

With NIRxWINGS2, you can move outside the lab into complex, dynamic, and multi-sensory real-world environments to conduct Systemic Physiology-Augmented fNIRS (SPA-fNIRS). The system enables new experimental paradigms and the creation of high-quality research databases.

New Feature: The NIRx BioLinkThe NIRx BioLink allows full customization of your sensor setup. It integrates sensor types RESP, ExG, EDA, and TEMP into a single sensor port, streamlining data collection while maintaining flexibility for your research needs.

FAQ

What physiological signals does the NIRxWINGS2 measure?

The NIRxWINGS2 is a physiological sensor module that measures peripheral signals including heart rate, respiration, tonic and phasic skin conductance (EDA/GSR), and SpO₂. These signals help account for systemic, non-neural activity in fNIRS recordings.

Why is measuring peripheral physiology important for fNIRS research?

fNIRS signals contain both evoked brain activity and non-evoked systemic noise. By simultaneously recording peripheral physiological data, researchers can statistically regress out systemic contributions, improving the signal quality and specificity of the neural hemodynamic response.

How does the NIRxWINGS2 connect to the NIRSport2?

The NIRxWINGS2 is designed to work natively with the NIRSport2 platform. Together they provide a combined LSL (Lab Streaming Layer) stream, ensuring seamless temporal synchronization between physiological and fNIRS data for multimodal analysis.

Does the participant remain wireless during recording?

Yes. Wireless data transfer allows participants to move freely throughout the recording session. Data is simultaneously stored on the device and streamed in real time, ensuring no data loss during mobile use.

Can the NIRxWINGS2 be used with other NIRx systems?

The NIRxWINGS2 is optimized for use with the NIRSport2 platform. Please contact NBT to confirm compatibility with other NIRx system configurations and to discuss your specific multimodal research requirements.
