Stimulus frequency #47

Open iampalop opened 2 years ago

iampalop commented 2 years ago

Hello, I am trying to make the presentation (selection matrix) to looks like no stimuli blink. So, I think I should change the stimulus frequency to a higher frequency, am I correct? Can I change the stimulus frequency?

Thank you so much in advance for your help.

Best, Pop

Hi Pop, Thanks for your question. Indeed, you can make the stimuli look like they are not flickering (even though they are) by increasing the stimulus frequency. However, at the moment the stimuli are running at the full frame-rate of your display (assumed to be 60Hz), so to make them go faster you will need a display with a faster refresh rate. For example, if you have your display set to refresh at 140Hz then the stimuli will automatically run at that speed.

I hope this answers your question -- and good luck with your neuro-hacking.
