Hjulopphenget

Hjulopphenget, also known as the wheel phenomenon or the wheel illusion, is an optical illusion that creates the perception of a spinning wheel. It is a type of motion aftereffect, where the perception of movement persists after the actual stimulus has stopped. The illusion is typically demonstrated using a spinning wheel or a series of rotating images. When the wheel stops, the perception of motion continues for a brief period, causing the viewer to see the wheel spinning in the opposite direction. This illusion is often used in studies of visual perception and motion processing in the brain. The hjulopphenget is a fascinating example of how the brain interprets and processes visual information, even when the actual stimulus is no longer present.
