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.
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.
At Artinis we consider ultimate success to be good publications by our customers. To see how we are doing we have systematically searched Google Scholar for NIRS and fNIRS publications.
