“…Changes in RFs are likely to warp visual space during saccades. Psychophysical studies in monkeys have suggested that RF shifts/ expansions may underlie saccadic mislocalization [6]. Human studies are consistent with findings on remapping in monkeys (see [7] for review).…”

Visual perception is based on both incoming sensory signals and information about ongoing actions. Recordings from single neurons have shown that corollary discharge signals can influence visual representations in parietal, frontal and extrastriate visual cortex, as well as the superior colliculus (SC). In each of these areas, visual representations are remapped in conjunction with eye movements. Remapping provides a mechanism for creating a stable, eye-centred map of salient locations. Temporal and spatial aspects of remapping are highly variable from cell to cell and area to area. Most neurons in the lateral intraparietal area remap stimulus traces, as do many neurons in closely allied areas such as the frontal eye fields the SC and extrastriate area V3A. Remapping is not purely a cortical phenomenon. Stimulus traces are remapped from one hemifield to the other even when direct cortico-cortical connections are removed. The neural circuitry that produces remapping is distinguished by significant plasticity, suggesting that updating of salient stimuli is fundamental for spatial stability and visuospatial behaviour. These findings provide new evidence that a unified and stable representation of visual space is constructed by redundant circuitry, comprising cortical and subcortical pathways, with a remarkable capacity for reorganization.

“…The perisaccadic shift also depends on flash duration (Jeffries et al, 2007;Van Wetter and Van Opstal, 2008). The main effect in the experimental data of Van Wetter and Van Opstal (2008) is that the localization error diminishes for longerlasting stimuli right at saccade onset (Fig.…”

Spatial perception, the localization of stimuli in space, can rely on visual reference stimuli or on egocentric factors such as a stimulus position relative to eye gaze. In total darkness, only an egocentric reference frame provides sufficient information. When stimuli are briefly flashed around saccades, the localization error reveals potential mechanisms of updating such reference frames as described in several theories and computational models. Recent novel experimental evidence, however, showed that the maximum amount of mislocalization does not scale linearly with saccade amplitude but rather stays below 13°even for long saccades, which is different from predicted by present models. We proposeanewmodelofperisaccadicmislocalizationincompletedarknesstoaccountforthisobservation.Accordingtothismodel,mislocalizationarises not on the motor side by comparing a retinal position signal with an extraretinal eye position related signal but by updating stimulus position in visual areas through a combination of proprioceptive eye position and corollary discharge. Simulations with realistic input signals and temporal dynamics show that both signals together are used for spatial updating and in turn bring about perisaccadic mislocalization.

“…Since little actual movement of the extraocular muscles took place, it is unclear why a largely stable retinal image should contradict the inflow signal and lead to perceived external motion. In addition, certain localization errors have been found to arise just prior to a saccade, before the eyes actually begin to move (e.g., Jeffries, Kusunoki, Bisley, Cohen, & Goldberg, 2007;see Ross, Morrone, Goldberg, & Burr, 2001 for a relevant review). This may suggest a slight temporal misalignment of corollary discharge with actual eye position (Honda, 1995;Matin, Matin, & Pearce, 1969;.…”

While our frequent saccades allow us to sample the complex visual environment in a highly efficient manner, they also raise certain challenges for interpreting and acting upon visual input. In the present, selective review, we discuss key findings from the domains of cognitive psychology, visual perception, and neuroscience concerning two such challenges: (1) maintaining the phenomenal experience of visual stability despite our rapidly shifting gaze, and (2) integrating visual information across discrete fixations. In the first two sections of the article, we focus primarily on behavioral findings. Next, we examine the possibility that a neural phenomenon known as predictive remapping may provide an explanation for aspects of transsaccadic processing. In this section of the article, we delineate and critically evaluate multiple proposals about the potential role of predictive remapping in light of both theoretical principles and empirical findings.Keywords Eye movements . Predictive remapping . Saccades . Transsaccadic integration . Transsaccadic perception . Transsaccadic processing . Visual stability During waking hours, our eyes dart from one location to the next about three times every second (Schiller, 1998). These fast, darting movements called saccades take place in alternating sequence with short periods known as fixations when the eyes remain relatively still. It is during fixations that we obtain useful information from the visual world, viewing a sort of 'snapshot' of the scene from the current vantage point (Neisser, 1967). Because only the fovea, a central region of the retina spanning about 2°of visual angle, is specialized for high acuity processing, we acquire detailed visual information from only a small part of the world during any given fixation (Jones & Higgins, 1947).Saccades allow the proximal stimulus of vision, the retinal image, to be selected quickly and efficiently based on processing requirements. Both the locations we fixate and the durations of our fixations reflect online selection of critical information from the visual environment (for reviews, see Rayner, 1998Rayner, , 2009). This seems an enormously beneficial attribute of the system. Our continually shifting gaze, however, also raises potential challenges for interpreting and acting upon the information acquired.First, the mobility of the eye raises the question of how we plan actions based on visual position information. Because our eyes move frequently about, a given retinal location does not map onto a unique location in space relative to the arms, legs, or other motor effectors. Therefore, some means of tracking the eye's current position relative to the effectors seems important for calculating the appropriate movement vector at any given moment. While this is a critical issue, it lies somewhat beyond the scope of the present article, which focuses more narrowly on how we perceive and represent the visual world across saccades (for reviews focusing on transsaccadic updating for motor control, see Klier & Angelaki...
