I am a student in electrical and electronics engineering. I just started working with EEG. I perform a stress test on subjects and record EEG activities with a 5-sensor headset. I use Matlab for analysis. I'm wondering if anyone can tell me the best method for data analysis. Do we expect the signal to be localized at a certain frequency range in the EEG data under stress stimulus? If so, what is the frequency range? Which filter should be applied to the EEG signal for the stress stimulus?

    $\begingroup$ Hi, welcome at CogSci. It very much depends on what you exactly are studying (e.g. ERPs, spectral power, coherence) and what kind of stress ( mental workload, physical straining, scare reflex) . Could you share some initial research you have done yourself about the matter, and perhaps explain a bit more about what you're studying. Otherwise, the question is too broad to receive a satisfying answer. $\endgroup$ – Robin Kramer Jul 12 '17 at 13:27
