“…However, it was demonstrated that the TAE decreased gradually at the present, presaccadic location of the adaptor and simultaneously increased at the future, postsaccadic location of the adaptor when observers were about to make a saccade. Similar findings were reported for the motion after-effect [16], and this apparent presaccadic transfer of visual after-effects has been interpreted within the predictive remapping framework. In other words, immediately before saccade onset, RFs of the adapted neuronal population are thought to shift along a vector equal to the impending saccade, and thus a decreased after-effect is observed at the presaccadic adaptor location.…”

Saccadic eye movements cause frequent and substantial displacements of the retinal image, but those displacements go unnoticed. It has been widely assumed that this perceived stability emerges from the shifting of visual receptive fields from their current, presaccadic locations to their future, postsaccadic locations in anticipation of the retinal consequences of saccades. Although evidence consistent with this anticipatory remapping has accumulated over the years, more recent work suggests an alternative view. In this opinion article, we examine the evidence of presaccadic receptive field shifts and their relationship to the perceptual changes that accompany saccades. We argue that both reflect the selection of targets for saccades rather than the anticipation of a displaced retinal image.

“…At the same time, interestingly, the aftereffect for stimuli presented at the fovea-the retinal location previously occupied by the adaptor-declined from previous levels. Biber and Ilg (2011) reported similar findings using adaptation to motion rather than tilted gratings. These findings have been proposed as evidence that predictive remapping affects perceptual experience.…”

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...

“…Turi and Burr (2012) showed that two forms of motion aftereffects (MAEs), which probably act at different neural levels of processing, are observed in different reference frames. In other words, when saccades are involved between adaptation and test stimuli, lower-level adaptation such as the classic MAE, in which prolonged exposure to a moving stimulus makes a stationary stimulus viewed subsequently appear to move in the opposite direction, is strictly encoded in retinotopic coordinates that shift with each eye movement (Biber & Ilg, 2011;Boi, Ogmen, & Herzog, 2011;Cavanagh et al, 2010;Knapen et al, 2009;Wenderoth & Wiese, 2008). In contrast, higher-level adaptation such as the positional MAE, in which the apparent position changes by adaptation to motion, is encoded in spatiotopic screen-based coordinates.…”

Effect of light level on the reference frames of visual motion processing

It is empirically known that some action-related visual tasks, which may rely on the construction of spatiotopic coordinates, are not well conducted under mesopic vision. The aim of this study was to clarify the effect of light level on the reference frame, such as retinotopic and spatiotopic coordinate bases, associated with visual motion processing. For this purpose, we used a phenomenon called visual motion priming in which the perceived direction of a directionally ambiguous test stimulus is influenced by the moving direction of a priming stimulus. Previous studies have shown that negative and positive motion priming are conspicuously observed in retinotopic and spatiotopic coordinates, respectively. In the experiments, participants made a saccade after the termination of the priming stimulus and judged the perceived direction of the test stimulus presented subsequently in retinotopic or spatiotopic coordinates at different light levels. We found that in retinotopic coordinates, negative motion priming was observed at all light levels. In spatiotopic coordinates, positive motion priming was observed at photopic and scotopic light levels, whereas the strength of motion priming was greatly reduced at mesopic light levels. These results were robust to the change in the luminance contrast or the saccadic eye movement per se. Different spatiotemporal properties of cones and rods at mesopic light levels may disturb the construction of a spatiotopic representation of motion, which leads to the disappearance of visual motion priming in spatiotopic coordinates during mesopic vision.
