I'm trying to find good documentation on using PsychoPy to measure Event-Related Potentials. In particular, I want to measure and compare the amplitude of the N170, a face-sensitive ERP, when presenting neutral versus threatening faces. I would be using the Emotiv Epoc EEG headset, whose validity for research on the N170 has been documented.

    $\begingroup$ Well I don't know for sure that it can do exactly what I want but I do know at least two things: 1/ there is a tutorial in the book "EEG Methods for the Psychological Sciences" on how to design an "EEG experiment" in PsychoPy. I don't have this book though. 2/ There is a discussion in the PsychoPy discussion group on how to make EPOC's software work with PsychoPy and the consensus is that it "should be feasible" by sending event code via a COM port. However, I couldn't find any confirmation that it has been done. $\endgroup$ – EsoEsMiNombre Mar 13 '16 at 2:49
  • $\begingroup$ @Seanny123, That said, I am open to any suggestion. It's possible that my solution is not very well thought out. $\endgroup$ – EsoEsMiNombre Mar 13 '16 at 3:00

    $\begingroup$ Psychopo can be easily used for presenting experimental stimuli for EEG/ERP experiments, including for N170 research. You usually send triggers to the recording computer to synchronize EEG recording and stimulus presentation. $\endgroup$ – jona Mar 15 '16 at 12:25

    $\begingroup$ Yes, PsychoPy can be used for administering an EEG/ERP experiment -- I've done it. However, I didn't use the Epoc system -- I used the BrainVision system. $\endgroup$ – Russell Richie Mar 23 '16 at 22:17

A collection of classic EEG experiments implemented in Python and Jupyter notebooks. Currently, all experiments are implemented for the Muse EEG device and using psychopy lib for stimulus presentation. Classification is made offline though. But I'll post very soon an online tutorial: https://github.com/NeuroTechX/eeg-notebooks/tree/master/notebooks

You can buy the book in particular Chapter 18: Building an EEG study. There is also the PsychoPy forum with 50+ questions about EEG. You could also go to the lead developers OSF page and steal some code there from his EEG experiments.
