How NIRS is used in brain-computer interfaces

How NIRS is used in brain-computer interfaces

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.

User insight: Observing NIRS research with the Artinis PortaLite on elderly

User insight: Observing NIRS research with the Artinis PortaLite on elderly

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.

PROMPT project: towards personalized treatment of mobility dysfunction

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).

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!

A research lab on wheels: unveiling the Sophia Bus

A research lab on wheels: unveiling the Sophia Bus

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.

A research lab on wheels: an interview with Dr. Sabine Mous

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.

The Brite is the only wearable fNIRS device worldwide that can measure the oxy-, deoxy- and total hemoglobin in every part of the head, e.g. prefrontal cortex, motor cortex, or visual cortex.

Combining the world of NIRS and EEG

Combining the world of NIRS and EEG

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.

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.
