Last week Artinis was present at the 2016 2f-NIRS conference in Montpellier, France. This two-day conference, titled NIRS signal: from acquisition to analysis, provided us with a great platform to not only display our products, but also to live demo the OctaMon and our new 3D software extension in a practical fNIRS workshop.
For the workshop we were set the challenge of performing a hyperscanning task: the mirror game. The results were very interesting.
For the mirror game task two participants were asked to slide a handle along a string. Participant 1, the follower, was asked to follow the movements of participant 2, the leader. The leader was told to move the handle in such a way that the follower would lose track of the leader. Two OctaMon were used in the experiment and the NIRS data was recorded by our software, OxySoft.
In the data you can clearly see that the leader shows more prefrontal activation than the follower. We saw similar results in all our experiments that day, 4 in total. It appears that improvising and creating new movements from scratch (the leader) is more demanding for the prefrontal cortex than to simply follow (follower).
We would like to thank Prof. Stephane Perrey and the organizing committee for organizing the 3rd 2f-NIRS conference and providing us with a great opportunity to demonstrate our products, the OctaMon and the 3D extension of OxySoft. We were delighted by the active participation of the researchers in our practical fNIRS workshop and were very pleased with the results. The OctaMon proved to be a very convenient device for hyperscanning experiments.

Imagine a person wearing a Brite and playing a demanding video game. This video game is difficult, and the mental workload is increasing drastically. Changes in blood volume, or hemodynamic changes, which are associated with the increase in workload is registered using the Brite. This blog will expand on how a NIRS-based BCI works and what researchers have made possible using NIRS-based BCI.
The third Artinis NIRS Symposium was a big success with valuable participants & fascinating NIRS discussions. Keep informed for ARTscientific 2019 impressions here and on our social media pages and see you at the next ARTscientific!
We like to incorporate the user from the very first beginning in our development process. Talking with researchers and clinicians, we get to know what’s driving them and what their expectations and suggestions are for our devices. We are constantly trying to understand their feelings and see the world from their perspective to optimize our NIRS devices. One way of doing this is observing and questioning the user that is working with the device, and subject that is wearing the NIRS device. This way, we are trying to gain new insights for existing and future NIRS products.
In this project we will focus on one of the most disabling symptoms of Parkinson’s disease, freezing of gait – episodic absence or reduction in the ability to produce an effective stepping in spite of the intention to walk (Nutt et al., 2011).
Short separation channels are the new trend in fNIRS. However, what is the functionality of such a short separation channel in brain oxygenation research?
A special thanks to our customers who published so many articles with our (f)NIRS devices and we hope you will keep on publishing in the future!
The Sophia Bus was an idea pitched by researchers from the Department of Child and Adolescent Psychiatry and Psychology within Erasmus MC-Sophia Children’s Hospital. As a national expertise center for many rare neurodevelopmental syndromes, children all over the Netherlands need to travel all the way to Rotterdam frequently to participate in research studies. The Sophia bus minimizes the burden for these patients by offering the solution to this problem: a mobile research lab that carries researchers to the patients’ doorstep.
fNIRS, as a neuroimaging method, was introduced more than two decades ago. Innovation in equipment, tools, and methods based on related-neuroimaging methods is increasing thanks to several companies and academic laboratories. The use of fNIRS in future research practices will aid in advancing modern investigations of human brain function. Connectivity measures will contribute to the field of neuroscience and a multimodal imaging approach is likely required.
Thanks to the very generous gifts of local companies and private individuals during the ‘Lichtjesactie’ (translates as ‘Candles project’) that was organized during Christmas time last year by the Stichting Vrienden van Sophia, the Sophia Childrens hospital were able to buy a camper van, which has been remodeled and transformed into a mobile research lab under close guidance of dr. Sabine Mous.
We offer the full spectrum of (f)NIRS devices, and all our devices can be mixed and matched to create your optimal setup within the same software. To aid you in finding the right device for your research we have drafted this comparative table below with the most important specifications for each device.
