Subject: Re: [AUDITORY] EEG - what hardware do you use to record triggers? From: Nike gnanateja <nikegnanateja@xxxxxxxx> Date: Sat, 5 Aug 2023 00:41:09 -0500--0000000000009033f6060226766a Content-Type: text/plain; charset="UTF-8" Hi Abby, I have a Biosemi too. I use neurobehavioral systems' presentation software for triggering. I use a startech parallel port pci card for the TTL trigger. Plus I have a creative labs audigy pci audio card. My triggers are pretty precise with this setup. Additionally, as a backup, I record the audio stimulus as an additional channel in the EEG. This gives me the ground truth of the audio in case for some reason the TTL triggers fail. I am happy to share any other specific details if you are interested.
