Neuronal control of fixation and fixational eye movements
WebFeb 27, 2017 · Abstract. Ocular fixation is a dynamic process that is actively controlled by many of the same brain structures involved in the control of eye movements, including the superior colliculus, cerebellum and reticular formation. In this article, we review several aspects of this active control.
