Motion artefacts in (f)NIRS — Not a problem, but not to be overlooked
Due to its portability and ease of use, fNIRS is applied in a variety of research fields, especially in study designs involving movement. Although fNIRS is relatively insensitive to motion artefacts, they still can occur and might influence signal quality. In this first part of our blogpost series on motion artefacts in NIRS, we explain what movement artefacts are and how they can be recognized.
Non-cerebral physiological interference in functional Near-Infrared Spectroscopy (fNIRS), a CURSE or BLESSING?
Our fNIRS devices offer a high sampling rate, enabling extraction of additional physiological parameters, including respiratory rate (RR). These parameters can provide important additional information that can be used as adjunction to cerebral activity measures. In this blogpost, the possibility of RR estimation from fNIRS in a resting state is discussed in the form of a case study.
Multimodal fNIRS-EEG measurements — Analysis approaches
When it comes to deciding on an appropriate data analysis approach in multimodal fNIRS-EEG measurements, the soundest consideration factors ultimately depend on the research question at hand. Therefore, the analysis steps may vary from one study to another. Nonetheless, they can broadly be classified into two strategies: parallel data analysis and informed data analysis.

OxySoft 4.0 unlocks easy export of NIRS data to .snirf format
The shared near-infrared file format (.snirf) is a standardized data format that was developed by (f)NIRS researchers to facilitate the exchange and sharing of NIRS data. Read this blog post to learn more about the .snirf format and how to export your data directly to .snirf in our latest software OxySoft 4.0!
Assessing NIRS signal quality – Implementation of the Signal Quality Index (SQI)
Achieving good signal quality is crucial for (f)NIRS data acquisition and analysis, but often difficult to determine. Therefore, we developed an algorithm named SQI (Signal Quality Index) which rates NIRS signal quality. Read this blogpost to learn more on how this SQI is specified and how it can be implemented in your research.
How to: Start a measurement and do a short analysis
