I am a student working on a project which deals with Steady State Visually-Evoked Potentials (SSVEP) Stimuator. Does anybody know where can I find stimuli (checkerboard or single graphic) as a video file? It's very difficult to find these files on the Internet. I am not allowed to use videos from youtube.
Researchers are often willing to share their stimuli. If you know of a paper that uses the same kind of stimuli that you want to use, you could try emailing the authors. A friendly request with a brief explanation of why you want the stimuli usually works.
