During gaze fixation, tiny eye movements, including slow ocular drifts, tremors, and microsaccades, continuously occur. Even though these eye movements have been known to exist for several decades, both their mechanisms of generation and their impacts on vision, perception, and cognition remain to be heavily under-investigated. Our aim is to explore such mechanisms with an emphasis on brainstem contributions.
