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.
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.
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.
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.
