Despiteprogress in elucidating theperceptual and neuronal effects offixational instabilities in specific, The significance of the miniature eye movements that we make during visual fixation has been intensely debated for the last 80 years. Recent studies have revealed that these motions of the eyes fulfill an important functional role: helping to extract useful information from natural scenes.
