Summary
Whether we are riding in a car or walking, our internal
map of the environment must be continuously up-
dated to maintain spatial constancy. Using a memory
eye movement task, we examined whether nonhuman
primates can keep track of changes in the distance of
nearby objects when moved toward or away from
them. We report that memory-guided eye movements
take into account the change in distance traveled, il-
lustrating that monkeys can update retinal disparity
information in order to reconstruct three-dimensional
visual space during motion in depth. This ability was
compromised after destruction of the vestibular laby-
