Motion artefacts in (f)NIRS — Hot to best detect them
Although fNIRS is relatively insensitive for motion artefacts, they cannot be completely prevented. Fortunately, there are various ways to detect motion artefacts. In this second part of our blogpost series on motion artefacts, we explain different methods of detections and elaborate on their advantages and disadvantages.
Artinis and NIRx join forces to accelerate innovation in brain imaging
Artinis Medical Systems, a pioneer in functional Near-Infrared Spectroscopy (fNIRS), is pleased to announce a strategic partnership with NIRx Medical Technologies. With the support of healthcare investor Gilde Healthcare, this collaboration marks a significant milestone in Artinis’ mission to advance neuroscience through accessible, high-impact neuroimaging solutions.
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.
Multimodal fNIRS-EEG measurements: Ensuring high-quality EEG recordings in integrated fNIRS-EEG setups
Combining fNIRS and EEG is gaining increasing popularity in neuroscience, allowing for the best of both worlds to be combined. One challenge in multimodality measurements can be interference (also known as crosstalk), especially when fNIRS optodes and EEG electrodes are placed close to each other. In this blog post, we demonstrate that it is possible to achieve high-quality EEG recordings without interference during simultaneous measurements with the Brite (fNIRS) and APEX (EEG) devices.
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.
Which experimental designs to use in fNIRS — Event-related design
Event-related study design is frequently used in fNIRS experiments, especially in naturalistic settings or multimodality setups. In this blogpost, we explain what event-related study design is, and dive into its advantages and considerations, as well as recommendations on how to best set up an event-related fNIRS study.
Comparison of fNIRS with other neuroimaging modalities – fNIRS vs. fMRI
fMRI is widely used and seen as the gold standard in non-invasive in-vivo brain imaging. However, due to its technology, it is comes with certain limitations in participant groups and experiments. fNIRS is portable, easy to use and can be applied in subjects of all ages. Hence, it can provide a valid alternative to fMRI in many applications. In this blogpost we discuss advantages that fNIRS has over fMRI, considerations that should be kept in mind and we highlight literature using fNIRS and fMRI to compare, or get complementary information.
Using a customized Brite during diving - a blogpost interview with Triton Systems, Inc.
As it is portable, customizable and easy to use, fNIRS can be applied to measure brain activity in various and unusual applications. In this blogpost, we interview Triton Systems, Inc., who modified the Brite to make it waterproof and use it to get insights on brain oxygenation during deep water diving. They explain challenges they faced during modification, and give insights into first results of applying fNIRS during diving.
Publication overview 2024 - mNIRS studies with our devices
In 2024, an increasing number of exciting papers measuring muscle NIRS with our devices have been published. In this blogpost, we depict application fields and purposes of using NIRS to measure muscle oxygenation, and highlight relevant studies published in the last year using Artinis devices per category. Further, we show recent publications targeting to assess reproducibility in muscle NIRS.
Publication overview 2024 - fNIRS studies with our devices
In 2024, an increasing number of relevant literature measuring brain activity with our fNIRS devices have been published. In this blogpost, we discuss application fields and purposes of using fNIRS to measure in the brain, and highlight exciting studies published in the last year with Artinis devices per category. Further, we show recent publications using our devices in naturalistic settings outside of the lab.
The Advantages of Combining fNIRS and EEG for Brain Monitoring
It is widely recognized that combining fNIRS and EEG can lead to a better understanding of brain activity by improving temporal and spatial resolution. However, the positive effects of simultaneously using both modalities go way beyond this advantage. In this blogpost, we highlight further benefits of applying the fNIRS-EEG combination to assess brain function in cognitive states.
Publication overview 2024 - Studies measuring brain and muscle oxygenation simultaneously using our devices
NIRS can be used to measure brain and muscle oxygenation at the same time to get a complete picture on oxygen status in the body. We are happy that in 2024 an increased number of studies using NIRS on brain and muscle simultaneously in various application fields was released. Read this blogpost to learn more about application areas of NIRS to assess cerebral and muscular oxygenation, and highlighted publications of last year per category.
