Cedrus Lumina Serial Emulator

The scanner at UCSB is always busy, leaving precious little time to get in and test your new experiment. You could stay late or come in during the weekend to get a turn on the magnet, or you can debug your experiment at your desk with a response emulator. This page on the prefrontal.org wiki has a set of instructions for creating your own emulator to provide a facsimile of the output provided by the Cedrus Lumina LP-400 box. It provides scanner trigger events every 2000ms with artificial subject responses following 250ms after each trigger.

I used this device extensively when I was programming some Psychtoolbox scripts. By getting all the big bugs out of your experiment before ‘going live’ and testing on a MR phantom you can save a lot of time, energy, and frustration.
