David,

Thank you for posting this! What is needed to connect this cable to the computer?

Do I need a DAQ box of some sort? If so, is there one you all would recommend?

Thank you!

@sjwest , I had assumed you already had BNC outputs from psychoPy or whatever software you already used for stim control. Can you detail what you currently do for stim presentation and synchronization of the stim presentation with data collection?

I have primarily used ePrime in my fMRI work and beyond programming the events our MRI tech handled the rest in terms of the hardware, so I am unsure of what set up they use. The NIRSport set up I have experience with used this sort of system: https://cedrus.com/support/m-pod/tn1872_nirx.htm - I just recently made the switch to psychoPy to make things more open source, but it effectively works the same way as ePrime in terms of presentation.

Each event has a set duration (or a known variable duration such as 2.5s/5s/7.5s) at which times trigger pulses are sent to the MRI. We create stimulus onset files on the back end in order to indicate the timing of presentation for the subsequent analyses.

I have the funds to purchase this, I am just wanting to make sure I select the correct interface.

Here is a simple part from Biopac that will give you analog outputs from ePrime.

I can look to see if I find something similar that works with psychoPy, but have to run now. More later.
