Hi all from an extreme BEGINNER :sweat:, I’ll be doing a MMN (Mismatch Negativity) experiment in which silent short videos are accompanied by sequences of auditory stimuli interrupted by odd/deviant sounds. This is my first experiment using PsychoPy and I’ve noticed that to add EEG triggers, one n…

Hardware wise, how are you connecting the computer running PsychoPy to the Brain Products amplifier? You might want to consider Cedrus’ c-pod or StimTracker products. The pyxid2 library needed to communicate with them ships with PsychoPy.

Hi from a different lab. I have a similar issue. Our computer and the BrianProduct amplifier is connected with a parallel port, and our script is created using a mix of builder and coder. I have looked at this BrainProducts — PsychoPy v2021.2.4 but I am unsure how and where to add parts of this co…

You will need a custom cable. It will have a DB25 connector on the parallel port side. On the other side, it’s either a DB9 for actiCHamp or a HD DB26. Of you can buy a ready-to-go c-pod for Brain Products . It connects to the computer’s USB port.

Thank you very much. I found that we have a c-pod in a cupboard, so I’m trying that now.

Thanks a lot @ingeborg.ribu … I’ll give it another look
