Stabilized images

Stabilized Images are images that remain immobile on the retina. Under natural viewing conditions, the eyes are always in motion. Small eye movements continually occur even when attempting to maintain steady gaze on a single point. Experiments by Riggs and Ratliff in the early 1950s established the remarkable finding that stabilized images result in the fading and disappearance of the visual percept.^[1] Some think that this demonstrates retinal adaptation to a stationary field^{[citation needed]}, but it may have a more profound involvement in the functioning of neural cliques, cell assemblies (cf. Hebbian theory) and patterns for memory^{[citation needed]}. More recently, work from Michele Rucci's laboratory at Boston University has indicated that stabilizing vision between saccades selectively impairs vision of fine spatial detail.^[2]^[3]

Images can be stabilized mechanically with optics mounted on the eye itself, or the image can be continually updated on a display to counteract the effects of eye movements.^[4] Because no existing method creates perfect image stabilization, this leaves open the question of whether all perfectly stabilized images disappear completely.^[5]
