Visual localization with eye movements: a review.

This paper reviews and discusses the most popular theories which have been proposed to account for the stability of the visual environment during eye movements. The subject is discussed chiefly from the stand-point of phylogeny rather than its contemporary treatment which attempts to explain neural mechanism by analogy with robotic systems or models. Certain conclusions are formed, and it is postulated that the constancy of egocentric directions following an eye movement is affected by the same mechanism that serves to retain the positional constancy of objects during the operation of the primitive postural reflex.
