P300 picture. When a rare and relevant stimulus appears, a P300 potential is elicited around 250 ms after the stimulus (Target). Otherwise, no particular brain response is observed (Non target). Here, due to our pipeline, another P300 response is elicited. Because the flashes are not strictly rare, the magnitude of the P300 is quite low. Finally, the difference between both conditions is depicted for information. The relatively small magnitude of the P300 peak is likely due to the non-rare occurrence of the target.
