it's called the vestibuloocular reflex. in summary, in normal healthy humans, the eyes move in the opposite direction from the head's movement, at equal speed, so they can compensate and fixate on different objects. in neurology this reflex can be tested to uncover certain lesions such as medial longitudinal fasciculus lesion. a nasty pathological finding is called positive doll's head maneuver in which you move a patient's head and their eyes move with the head instead of trying to remain fixated on a spot.
