motion aftereffect
The motion aftereffect is a phenomenon where, after observing motion in one direction for a prolonged period, a stationary object appears to move in the opposite direction when you look away. This happens because the visual neurons that detect motion become fatigued. When you shift your gaze, the fatigued neurons respond less, while the neurons for the opposite motion remain active, creating a perception of reverse motion. It's a fascinating example of how our brain processes visual information and adapts to stimuli in our environment.

The Motion Aftereffect (MAE) is a visual phenomenon where, after watching a moving object for a while, stationary objects appear to move in the opposite direction. For example, if you observe a waterfall for several minutes and then look at the rocks nearby, they might seem to flow upward. This occurs due to the way our brain processes motion. When we focus on a specific direction, the cells in our visual system that detect that motion become less responsive. Once the stimulus is removed, the opposing motion is perceived, leading to this intriguing aftereffect.

The motion aftereffect, also known as the "waterfall effect," is a visual phenomenon where, after staring at a moving object for a while, stationary objects seem to move in the opposite direction when you look away. This occurs because the neurons in our visual system become fatigued from processing the constant motion. When you shift your gaze, those neurons recover, causing a temporary imbalance in perception. This fascinating effect illustrates how our brain interprets motion and highlights the complex workings of our visual system.
