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.
On May 11th-13th, 2017 we will organize the first Artinis symposium in the Netherlands. Our aim is to create an open platform for both experienced and novice researchers, scientist and academic students. During this 2,5 day course we offer lots of hands-on experience, (NIRS) workshops, social events and possibilities to share your experiences with us and other attendees.
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.
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 while using the PortaLite.
