<p>We now use both STIM2 via chaning a jumpter cable on our old (STIM1) Stim box and purchasing STIM2 software that has the major advantage of precise timing of events. We also are successfully using EPrime and have also used SuperLab. These later programs
have substantial delays between stimulus presentation computer and the actual data display (on Scan Acquire) so it is especially important to check the difference between the stimulus computer command and the actual display on the Scan EEG signal. For visual
stimuli, this can easily be done using a photo-resistor positioned between a high ohm resistor (e.g., 100K) and a low ohm resistor (e.g., 2K). You then add a 1.5 V battery attached to the an end of high ohm resistor and the other end on the distal end of the
low ohm resistor. You then tap the reduced (roughly 30 uV voltage that is produced across the two sides of the low-ohm resistor and input one of these leads into input box ground and the other into an active EEG channel. With changes in the stimulus presentation
luminosity the voltage will increase or decrease in a nearly instantaneous manner. </p>

<p>I was wondering if anyone could recommend a good open-source presentation software that is compatible with Neuroscan. We are looking to move away from STIM, but need a program that would be compatible with the Neuroscan/STIM hardware so we can properly send
out triggers. </p>

<p>Thank you for your advice!</p>
