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.
The artificial induction of ischemia (from Greek, meaning stopping/keeping back blood) was first shown to help protect cardiac muscle from injury in later occurring episodes of ischemia by Charles Murry and colleagues in 1986. This technique came to be called ischemic preconditioning (IPC).
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.
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.
