Question

Quizplus · Accepted Answer

The ability to see the light trail after the initial stimulus of the sparkler is facilitated by persistence of vision. This refers to the way that the retina retains an image for a brief moment after it has disappeared, allowing the brain to perceive a continuous stream of light even when the actual stimulus is intermittent, such as with the sparkler drawing. End-stopped neurons, bottom-up processing, and top-down processing are not relevant to this phenomenon.
