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).
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.
You can win a Brite system for your research project! What do you need to do? We ask you to write a short proposal, 2 pages maximum, of your research project. The most outstanding proposal will win Artinis Brite for the entire duration of your data collection period.
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.
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.
How do we know that the most active channels are located over the brain region of interest and not somewhere else? Of course, an experienced researcher just knows where to place the optodes, but is that enough to convince a potential highly-critical reviewer or fellow scientist?
Dr. Marc van Wanrooij and his team from the Hearing and Implants lab used a 48-channel OxyMon to study temporal cortical activation as represented by concentration changes of oxy- and deoxy-hemoglobin in 48, easy-to-apply optical fNIRS channels.
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 give a mirror game workshop with two OctaMon devices.
Food is important for a healthy development of body and brain. But how do we get an insight into what nutrition is good for us? Artinis will provide a user-friendly, plug-and-play device to measure the effect of cognitive interventions on children using the NIRS technique.
