Motion perception is the ability of the visual system to detect and interpret movement in the environment. This process involves specialized cells in the brain that respond to changes in position and speed of objects. Motion perception helps us navigate our surroundings, avoid obstacles, and interact with moving objects. The brain uses various cues to perceive motion, including optical flow, which refers to the pattern of visual changes as we move, and motion parallax, where objects closer to us appear to move faster than those farther away. These mechanisms work together to create a coherent understanding of motion in our visual field.
