Summary: Saccadic suppression is attenuated during learning on a visual detection task, eventually being effectively silenced. The changes in sensitivity during learning are accompanied by a systematic impact of saccades on performance. This silencing of suppression is not explained by changes in saccade characteristics, and it generalizes to untrained retinal locations and stimulus orientations.

Summary: The study found that visual disturbances in schizophrenia patients were not related to saccadic suppression, but were related to saccade amplitudes. Patients showed reduced saccade amplitudes in the saccadic suppression task, possibly due to cognitive load.

Summary: Visual perception remains stable across saccades because of the reduction in visual sensitivity known as saccadic suppression. This suppression is achieved through three independent mechanisms in the retina.

Summary: This research examines the effects of saccadic suppression on neural subpopulations in visual area V4. The study shows subpopulation-specific differences in peri-saccadic modulation and identifies the involvement of inhibitory interneurons in saccadic suppression. A computational model is used to demonstrate how eye movement signaling interacts with cortical circuitry to maintain visual stability.

Summary: Visual stability during eye movements requires discerning self-generated motion from external motion. In the laboratory, researchers often study visual stability by asking observers to discriminate the direction of target displacements during saccades. It is well-established that performance in this paradigm is usually poor. This study found that participants mislocalized the pre-saccadic target to the physical position of the post-saccadic target, but only after backward displacements.

Summary: The processing of visual information in the central and peripheral visual field varies, and the visual system compensates for these differences by introducing subtle changes during eye movements, leading to an impact on the bias towards circularity increase in change-discrimination tasks.

Summary: The perception of brief visual stimuli is strongly diminished across saccades, with suppression potentially starting in the retina. The strength of saccadic suppression is influenced by background luminance and flash luminance polarity. This suggests that perceptual saccadic suppression may be fundamentally a visual phenomenon.

Summary: Saccadic eye movements modulate visual perception by initiating and terminating high acuity vision at specific locations, but also causing a temporary decrease in visual contrast sensitivity. This study found that saccadic suppression for luminance and color is present in most participants independent of age, with a slight age-related increase in suppression strength observed only for luminance.

Summary: It is unclear how facilitation and suppression processes interact for target selection during covert and pre-saccadic attentional shifts. A recent study found greater suppression at unattended locations during trials with saccades compared to trials without saccades. However, it is unknown whether this finding is restricted to countermanding paradigms that involve inhibitory processes.

Summary: How does the brain maintain an accurate visual representation of external space? Movement errors following saccade execution provide sufficient information to recalibrate motor and visual space. We investigated whether spatial information for vision and saccades is processed in shared or separate resources, and found that the recalibration processes for saccades and visual space are separate.

Summary: This study evaluates 16 differentiation methods by designing an experiment using synthetic saccadic electrooculograms, generated from parametric models of healthy subjects and subjects suffering from SCA2, to determine the best fitting method for saccade identification and saccade biomarker computing tasks.

Summary: Drosophila uses smooth optomotor movements to stabilize gaze and impulsive saccades to pursue vertical bars, with T4 and T5 cells providing inputs for gaze stabilization and T3 cells driving bar tracking body saccades. Silencing T3 reduces tracking saccades, while optogenetic manipulation affects saccade rate. Smooth optomotor responses remain unaffected. Parallel neural pathways coordinate gaze stabilization and saccadic bar tracking behavior in flight.

Summary: Trans-saccadic memory involves tracking object locations and features across saccades, with limited resources and attentional involvement. Previous research showed that recognition of post-saccadic objects is impaired when pre-saccadic objects are relevant. This study investigated how abrupt post-saccadic changes affect pre-saccadic memory, finding that attentional facilitation to pre-saccadic objects can mitigate disruption caused by post-saccadic changes.

Summary: This study is based on a part of the saccadic model and introduces a differentiable new model by using the Naka-Rushton function. The novel system is transformed into a discrete model using the forward Euler method, and its dynamical features are described using center manifold theory. Analytical and numerical simulations are used to investigate the period-doubling bifurcation in the saccadic model based on numerical parameters.

Summary: Patients with migraine, both with and without aura, show increased saccade latency specifically in the anti-task, suggesting a specific deficit in generating correct anti-saccades potentially related to cortical networks. This finding may provide insights into the understanding of how different brain regions are involved in the pathophysiology of migraine.
