A New Frontier for Neuroergonomics
We are happy to announce that the University of L’Aquila (Italy) research group utilized the 20-channel Oxymon in an important study for neuroergonomics (Carrieri M, Petracca A, Lancia S, Basso Moro S, Brigadoi S, Spezialetti M, Ferrari M, Placidi G and Quaresima V, 2016):
Prefrontal Cortex Activation Upon a Demanding Virtual Hand-Controlled Task: A New Frontier for Neuroergonomics.
Neuroergonomics is an interdisciplinary area of research which involves the intersection of two disciplines: neuroscience and ergonomics.
The study investigated the prefrontal cortex during the execution of a novel virtual hand-controlled task. The hand movements were captured by a 3D hand-sensing device, the LEAP motion controller, a gesture-based control interface that could be used in virtual reality for tele-operated applications such as driving robots, rovers and other devices remotely in a critical environment. The results showed the bilateral involvement of a specific cortical region, the ventrolateral prefrontal cortex, in response to the hand-controlled task.
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 animals. 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.
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.
