Prof. Martin Burtscher and Prof. Robert Koch from the University of Innsbruck (Austria) put their knowledge on hypoxia research into practice when climbing the highest volcano of the world (Ojos del Salado, 6893 m) situated in the Atacama desert in Chile (South America).
Due to an optimized acclimatization program (amongst other supported by PortaLite measurements) they were able to perform the overall travel within just 14 days. Pre-acclimatization has been started in the Alps and the hypoxia chamber of the University of Innsbruck; acclimatization has been continued in the region around Putre (Lauca national park, 3650 – 5700 m). Then they climbed within 5 days by car and by foot from Copiapó (383 m) close to 7000 m.
Due to their experience and repeated measurements of various physiological parameters (including cerebral oxygenation measured by NIRS with the PortaLite), they controlled acclimatization on an individual basis and were able to perform this high-altitude sojourn without any symptoms of acute mountain sickness.
While being used in a challenging environment and at the same time facing low temperatures, the application of the PortaLite proved to be very successful throughout the research.
Next to quality equipment, according to the Professors an appropriate fitness level and climbing skills, adequate diet and good luck with the weather are also essential to perform a successful high-altitude research.
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.
