Measuring brain activity during playing a competitive checker game – a fNIRS hyperscanning mini study

In hyperscanning, brain activity and connectivity of multiple subjects are measured simultaneously during social interaction, for instance in competitive situations. fNIRS is often used as neuroimaging technology for hyperscanning in cognitive studies due to its portability and relative insensitivity to movement artifacts. In an internal mini-study, we tested the use of Brite Frontal to perform hyperscanning while participants played a competitive game of checker.

Exploring the infant brain with fNIRS

Testing young babies, between 0 and 2 years of age, is definitely fun, but it also comes with challenges. We asked several developmental researchers to point out the main difficulties they typically encounter and what features an infant-friendly NIRS should have. So, what are these challenges and what can researchers and technology do to overcome them?

fNIRS analysis toolbox series – Homer

Here we present Homer3, an open-source MATLAB toolbox for analysis of fNIRS data and for creating maps of brain activation. In this blog post, we present the basic principle of Homer3 and show a simple example of how to read in data, preprocess the data (filtering only), average over trials as well as over subjects, and plot the final result in a graph.

fNIRS analysis toolbox series – FieldTrip

Here we present FieldTrip, which is a MATLAB analysis toolbox that was originally designed for electrophysiological data analysis. However, FieldTrip supports fNIRS data analysis as well. It contains high-level functions that can be combined in a MATLAB script. It aims at researchers with a background in neuroscience, engineering, optics and physics.

fNIRS analysis toolbox series – NIRSTORM

Here we present NIRSTORM, a NIRS analysis plugin for the MATLAB-based MEEG Brainstorm toolbox. It is aimed at researchers with a background in neuroscience, engineering, optics and physics. Here, we present the basic principle of NIRSTORM and show a simple example of how to go from raw data to a visualisation of the average response over trials and sessions.

fNIRS analysis toolbox series – OxySoft

OxySoft is our proprietary, and dedicated, NIRS software used to collect, store, view, and analyze all necessary data. Here, we present the basic principle of data analysis within OxySoft itself and show a simple example of how to read in data, preprocess the data (filtering only), average over trials and over subjects and plot the final result in a graph. Finally, we will show how to get the data into a format suited for statistical analysis.
