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: 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: 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: 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: Drawing on Conservation of Resources theory and its notion of resource passageways, this study investigates the relationship between resilience and workability, and examines how differences in perception between leaders and employees about the use of pressure or rational persuasion as influence tactics affect this relationship. Using a two-wave time-lagged survey design with a sample of 146 leader-follower dyads, the findings suggest that leader-follower perceptual differences about the use of pressure as an influence tactic buffer the positive resilience-workability relationship of followers, while no similar effect was found for rational persuasion.

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: Land surface utilization in the Indian subcontinent has significant impacts on the region's monsoon rainfall. An increase in forest cover generally leads to more precipitation in India, but the relationship is not linear due to spatial heterogeneity. The consequences of land surface alterations act through evaporation, net energy input, and moist stability, with different mechanisms dominating different regions. The findings have broader implications for other forcings and scenarios.

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 study found that individuals with higher HIV-1 envelope gene diversity have higher neutralizing titers against a global HIV-1 reference panel, but limited neutralization against autologous viruses. The inducible reservoir is relatively resistant to autologous antibodies, but sensitive to broadly neutralizing antibodies (bNAbs). Individuals with limited virus variation in the env gene, such as those who start ART early in infection, are more likely to be sensitive to bNAb treatment.

Summary: The study found that the amplitude of prestimulus alpha oscillations is significantly higher before stimuli that remain subjectively visible compared to those that become perceptually suppressed. Additionally, individual prestimulus alpha amplitudes are strongly correlated with trial-to-trial variability quenching following motion stimulus onset, indicating a close relationship between prestimulus alpha activity and variability quenching in the visual cortex.

Summary: This study evaluated the effects of water span and the number of building levels on human recovery, security, and overall experience. The wider the water span, the lower the perception of security. Low and multi-storey buildings had the best effects on human recovery quality, security, and overall experience. Including birdsong in waterfront high-rise settings is desirable.

Summary: Through experiments and neuroimaging, it has been found that alpha and beta oscillations in specific brain regions in humans are associated with the accumulation of sensory evidence and motor preparation, respectively.

Summary: The article introduces a simple evaluation methodology for assessing ships' stability, called SEMIS, which is validated through deriving empirical formulas and comparing them with principal calculation methods. The study shows that SEMIS efficiently evaluates ships' stability using only GM.

Summary: Progressive addition lenses introduce distortions in the peripheral visual field. This study investigates how our peripheral visual field adapts to complex distortions. The environment can tune perceived object trajectories and adaptation to geometrical distortions affects the double-drift illusion.

Summary: Through a frequency-tagging paradigm, this study investigated how sustained visual-spatial attention modulates steady-state visual evoked potentials. The results showed that participants selectively attended to the cued visual hemifield, and when attending to visual stimuli, there were larger second harmonic SSVEPs with no attentional modulation of the first harmonics.

Summary: This study observed that people make large dynamic overshoots when making a saccadic eye movement within a blink but their eyes are back on target by the time the eyelids are open. We used electrooculography (EOG) to measure eye movements even when the lid is down and introduced a novel procedure to subtract blink-related EOG components. These findings challenge the current view that within-blink saccades are programmed as slow but straight saccades.

Summary: Eye movements are closely related to human cognitive processing, but current methods cannot measure all possible eye movements. This study introduces a new automated method using real-time magnetic resonance imaging for eye tracking, which can measure both rotational and translational eye movements with high temporal resolution. This method provides new opportunities for studying ocular motility and its disorders.
