“…Their results demonstrate that saccadic suppression is strongest for the low spatial frequencies (below 1 cycle per degree), while higher spatial frequencies remain largely unaffected (Wolf et al, 1978(Wolf et al, , 1980Burr et al, 1994). This selectivity of suppression to the magnocellular pathway strongly suggests that this type of suppression is specific to motion signals (see, e.g., Ross et al, 2001).…”

Why and how people perceive the visual world as continuous and stable, despite the gross changes of its retinal projection that occur with each saccade, is one of the classic problems in perception. In the present paper, we argue that an important factor of visual stability and transsaccadic perception is formed by the reafferent visual information, i.e., the visual display that is present when the eyes land. After a review of some of the relevant theoretical, behavioural and physiological research on space constancy, saccadic suppression and transsaccadic memory, three experiments are presented. In a first experiment, we study the effect of an extended horizontal bar covering the target area for a short period after the saccade on saccadic suppression of image displacement. The results show that the bar acts just like a temporary blanking of the saccade target, leading to a strong reduction of saccadic suppression. In the second experiment, we show that any object that is present immediately after the saccade can establish a spatial reference, even if it is dissimilar to the saccade target. In a third experiment we study, with a similar approach, the effect of blanking and postsaccadic information on transsaccadic integration of form information. The data demonstrate that a localized postsaccadic object tends to replace the content of transsaccadic memory.

“…While it as been speculated that other phenomena, such as a translation in cortical coordinates [107] or a stretching [108] or jumping [84] of receptive fields, could also account for mislocalization of visual stimuli towards the saccade target, the spatial re-entry model seems so far the most comprehensive account for the data of peri-saccadic compression. As it stands, the model explains the above-mentioned effects in a retinocentric frame of reference.…”

Perceptual phenomena that occur around the time of a saccade, such as peri-saccadic mislocalization or saccadic suppression of displacement, have often been linked to mechanisms of spatial stability. These phenomena are usually regarded as errors in processes of trans-saccadic spatial transformations and they provide important tools to study these processes. However, a true understanding of the underlying brain processes that participate in the preparation for a saccade and in the transfer of information across it requires a closer, more quantitative approach that links different perceptual phenomena with each other and with the functional requirements of ensuring spatial stability. We review a number of computational models of peri-saccadic spatial perception that provide steps in that direction. Although most models are concerned with only specific phenomena, some generalization and interconnection between them can be obtained from a comparison. Our analysis shows how different perceptual effects can coherently be brought together and linked back to neuronal mechanisms on the way to explaining vision across saccades.

“…Our recording and inactivation findings therefore indicate that a major function of the SC-MD-FEF pathway is to convey corollary discharge (for critical evaluation of this study by others, see [56,57]). This corollary discharge contributes to coordinating sequential saccades and may help to stabilize the perceived visual scene across saccades by warning the visual system about imminent retinal rotations [58,59].…”

Two characteristics of the thalamus -its apparently simple relay function and its daunting multinuclear structure -have been customarily viewed as good reasons to study something else. Yet, now that many other brain regions have been explored and neurophysiologists are turning to questions of how larger circuits operate, these two characteristics are starting to seem more attractive. First, the relay nature of thalamic neurons means that recording from them, like tapping into a wire, can reveal the signals carried by specific circuits. Second, the concentration of like relay neurons into nuclei means that inactivating or stimulating them can efficiently test the functions of the circuits. Recent studies implementing these principles have revealed pathways through the thalamus that contribute to generating movements and to monitoring one's own actions (corollary discharge).
