Abstract--Spatial updating is the means by which we keep
track of the locations of objects in space even as we move.
Four decades of research have shown that humans and non-
human primates can take the amplitude and direction of in-
tervening movements into account, including saccades (both
head-fixed and head-free), pursuit, whole-body rotations
and translations. At the neuronal level, spatial updating is
thought to be maintained by receptive field locations that
shift with changes in gaze, and evidence for such shifts has
been shown in several cortical areas. These regions receive
information about the intervening movement from several
sources including motor efference copies when a voluntary
movement is made and vestibular/somatosensory signals
