Publication Overview with our NIRS devices in 2022 – Muscle
We are proud that several papers using our NIRS devices to measure muscle oxygenation from different body parts and in various application fields were published in 2022. Read this blog post to get an overview of application areas NIRS can be used in, and which devices can be applied. Also, find highlighted publications per category that were performed with our devices in 2022.
Set up the PortaMon in 6 steps - NIRS device for muscle oxygenation measurements
With the PortaMon, it is possible to perform both online measurements easily through Bluetooth connection, as well as offline measurements over a larger distance, as data can be stored on the device and downloaded afterward. Watch our newest video and discover how to correctly set up the PortaMon in only six easy steps!
Exploring the infant brain with fNIRS
Testing young babies, between 0 and 2 years of age, is definitely fun, but it also comes with challenges. We asked several developmental researchers to point out the main difficulties they typically encounter and what features an infant-friendly NIRS should have. So, what are these challenges and what can researchers and technology do to overcome them?
Brite MKII: Wearable, Highly-Flexible, Optimized, Accurate NIRS!
Meet the latest Artinis wearable NIRS system, designed for brain imaging in a wide range of settings and populations. Optical imaging was never so easy!
Heart rate extraction from NIRS signal
A commonly asked question is “What are the advantages of NIRS over EEG?”. NIRS signals are, in general, less susceptible to artifacts like motion artifacts or electrical noises. There are, however, also physiological components such as heartbeat, breathing, and Mayer-waves present in the signal. Although not an artifact, these components are usually filtered out since they are not useful in determining the pure hemodynamic response signal of the brain. Nevertheless, there is interesting information in the heartbeat. In this blog, we talk about taking advantage of the heartbeat in the NIRS signals and extracting the heart rate signal from them.
How to clean your Artinis NIRS systems and accessories?
COVID-19 has had a major impact on all of us. For a while, Universities were closed and research was put on hold. Now slowly but surely, we are going back to the labs and starting our experiments again. NIRS experiments include contact with patients and research participants, we therefore find it important to inform you about how to clean the Artinis NIRS devices.
The importance of being precise: using PsychoPy for stimulus presentation and OxySoft for triggering
You’ve got your NIRS device ready and have already thought of the protocol for your next experiment. You have a clear picture of it in your head: you can see the subjects with the NIRS cap on facing a PC monitor showing each of the instructions and stimuli at the exact timing you were aiming for. Timestamps for each event are automatically saved and once the session is over, you are ready to go for the analysis. Sounds nice, right? How simple is it, though? Well, turns out it’s quite simple, actually. You just need the right tools, and the combination of PsychoPy and Oxysoft is a perfect match!
Artinis Literature Overview 2019 - Exercise physiology
From a classical perspective, we at Artinis separate the publications into the domain of functional brain monitoring and muscle research. ‘Brain’ - and ‘Sports’ people. This review will highlight a handful of publications in the domain of movement science published in 2019’s.
Exercise Physiology integrating NIRS, ECG, and EMG as a learning tool
Innovations travel back and forth between different departments within Artinis. Application Specialists give insight in customer requests, Research and Development find new measurement methods, Design and Engineering constantly look for further improvement of the equipment and Sales and Support find new ways to support every single customer. Especially for new employees, hands-on experience throughout the company is crucial in their development and no better way to do this than to set up a study.
Submersible NIRS: a very wet lab...
In 2016 dr. Chris McKnight approached Artinis with the idea to measure NIRS under water on wild animals. Initially there was some skepticism, since our devices are not intended to be taken underwater, let alone on a wild animal. However, we really liked the challenge and together with the Sea Mammal Research Unit (SMRU) of the University of St. Andrews we created a submersible NIRS-sensor specifically for the seals.
Can restricting blood flow improve sports and exercise performance?
The artificial induction of ischemia (from Greek, meaning stopping/keeping back blood) was first shown to help protect cardiac muscle from injury in later occurring episodes of ischemia by Charles Murry and colleagues in 1986[1]. This technique came to be called ischemic preconditioning (IPC).
