At Artinis we consider ultimate success to be good publications by our customers. To see how we are doing we have systematically searched Google Scholar for NIRS and fNIRS publications using a custom-made Matlab script. This resulted in a total of 46 NIRS devices from 16 different manufacturers. Any publication with the term NIRS, fNIRS or near-infrared spectroscopy was included. Subsequently, all articles were scanned for used device and manufacturer. The results are amazing, thanks to our customers we are proud to be world leading in (portable) NIRS research publications, with over 100 publications in 2016!

As an application Specialist at Artinis Medical Systems I get asked a lot what the differences are between lasers and LEDs. So, therefore a small blog to answer this question once and for all. Both laser and LED have their specific pros and cons. It depends very much on your research requirements what technique is best for you. I have broken down the differences in measuring depth, portability, pricing, wavelengths and safety in this blog.
Watch how easy setting up your Brite is!
The Brite is the only wearable fNIRS device worldwide that can measure the oxy-, deoxy- and total hemoglobin in every part of the head, e.g. prefrontal cortex, motor cortex, or visual cortex.
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. This technique came to be called ischemic preconditioning (IPC).
EEG and fNIRS are complementary measuring techniques. EEG measures electrophysiological brain activation, that is the electromagnetic field created when neurons in the brain are firing. fNIRS measures the hemodynamic response, that is the change of oxygen in the blood when a brain region becomes active. By combining EEG and fNIRS, a more complete picture of brain activity is obtained: activation of neurons and energy demand of neurons.
Over the years we have developed both hardware-based and software-based options for data synchronization. In this blog we will explore the different options and discuss the advantages and disadvantages of each.
A common question we get from our customers is what is a baseline and how to use it. Generally with fNIRS, the absolute values are arbitrary. The period before a stimulus is often referred to as the baseline. In this blog we will describe the do's and don'ts of baselines.
