functional Near Infrared Spectroscopy

At the Cognitive Systems Lab, we use functional Near Infrared Spectroscopy (fNIRS) to build innovative user interfaces. The fNIRS technologie uses light in the near infrared part of the electromagnetic spectrum to measure oxygen concentrations in cortex areas of the brain. The technolgoe is portable and quickly mounted on the head.

Public data corpus

 

Single trial analysis of fNIRS data is still a very young field and there are almost no publicly available datasets. Therefore, we share the data that was recorded for our n-back study.

The paper titled "Mental workload during n-back task—quantified in the prefrontal cortex using fNIRS" can be found here.
