Hi I’m a computer science student but I want to measure EEG asymmetry in people’s reaction in a VR scene. I’m using Muse 2016 (one of the only devices that fit with a VR headset), and using Muse Monitor for exporting data.
I have several questions:
Which frequency band should I look at? I’ve seen people using alpha, beta, gamma, but still not sure about it.
Is the change in frontal asymmetry time-related? Is it visible on the graph upon the onset of a stimulus? If not, should I compute the mean or median value of the entire duration of the experiment? (currently I visualized beta band but the graph looks very random to me.)
How should I preprocess the data from Muse Monitor (compute baseline, de-noise)? Is there any method or algorithm I can implement by hand? Since the Muse band is not a scientific tool, I can’t find any toolbox (for Matlab, for example) to process the data.
Sorry I’m a Computer Science student and just started learning about EEG so any advice on how to make the most of the data from the Muse device will be great help to me!
