Question

Quizplus · Accepted Answer

Persistence of vision is the phenomenon where an image continues to be processed by the brain even after the visual stimulus that caused the image has been removed. This allows us to see the light trail of the sparkler even after it has moved beyond our field of view. Option B, end-stopped neurons, are neurons that respond only to specific points or endpoints within a visual stimulus, and are not relevant to the question. Options C and D, bottom-up and top-down processing, refer to the ways in which we process and interpret visual information, but are not specifically related to the ability to see the light trail of the sparkler.
