Do you know any good tutorial on designing EEG experiments with PsychoPy? 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.
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:
