vestibulo-ocular reflex 전정안근반사
두위(頭位)의 변화는 전정기관(前庭器官)에서 검지되어, 대상성안위의 변화가 일어나, 시선을 일정하게 유지하도록 한다. 이것을 전정안근반사라고 한다.

"The VOR does not depend on visual input and works even in total darkness or when the eyes are closed."
"The vestibulo-ocular reflex needs to be fast: for clear vision, head movement must be compensated almost immediately; otherwise, vision corresponds to a photograph taken with a shaky hand. To achieve clear vision, signals from the semicircular canals are sent as directly as possible to the eye muscles: the connection involves only three neurons, and is correspondingly called the three neuron arc. Using these direct connections, eye movements lag the head movements by less than 10 ms, and thus the vestibulo-ocular reflex is one of the fastest reflexes in the human body."
