Summary: Reliable and noninvasive biomarkers are important for neurological diagnoses. Microsaccades, small eye movements, have been proposed as a biomarker for attention, but their direction may not accurately reflect covert spatial attention in complex viewing conditions.

Summary: The study found that exogenous attention transiently modulates visual detail in the foveola, enhancing detail discrimination ability at the cued location without extending to nearby locations. On a longer timescale, an inverse effect was observed, with sharper acuity at unattended locations resembling inhibition of return at larger eccentricities.

Summary: Scan pattern analysis has been discussed as a promising tool in real-time gaze-based applications, with research evaluating active information storage as a novel approach to quantifying predictability. Results from a driving simulator experiment showed that some observers exhibited temporal correlations beyond a single past fixation, with the length of correlation varying between observers.

Summary: The computational model presented is based on the Active Efficient Coding framework and is capable of developing disparity tuned neurons and precise eye control under normal rearing conditions, as well as reproducing experimental results under altered conditions. The model predicts how altered rearing conditions affect the learning of precise eye control, and also reveals a surprising effect on the statistics of orientation tuning in visual cortical neurons when vergence control is impaired.

Summary: Research shows that drivers tend to look further ahead when under automated vehicle control, but gaze patterns remain consistent across manual and automated driving modes with similar waypoint-tracking gaze patterns.

Summary: Learning to categorize involves attending to relevant features and ignoring irrelevant features, with feature variability across objects aiding in inferring category membership rules. While participants' categorization accuracy improved with practice, their attentional focus did not show improvement. Despite eyes being a salient feature attracting attention, participants gradually learned to ignore them during the learning process.

Summary: When fixating an object, our eyes do not remain stationary but constantly drift, and it was previously believed that this drift was random and involuntary. However, a recent study has found that the direction of eye drift is not random but is influenced by task demands to enhance performance.

Summary: This study tracks the hand movements of participants during a shape recognition task and identifies two dominant strategies: contour following and scanning. These strategies are specific to the sensed object and are influenced by the physiological parameters of the perceiver.

Summary: Research shows that microsaccade dynamics contribute to Troxler fading and intensification, even when viewing representational art. Observers' eye movements play a role in the cornerstone of Impressionism.

Summary: By training adults to perceive remote objects through their fingers using a sensory substitution device, participants quickly learned and maintained a high level of performance for over 20 months. Both sighted and blind participants showed almost complete transfer of performance from 2D images to 3D objects, with perceptual accuracy and speed using the device improving significantly.

Summary: This study found that damage to the primary visual cortex (V1) can result in loss of conscious perception but does not necessarily affect unconscious abilities. Patients with V1 damage were still able to perform accurate saccades and automatically track target motion in their intact fields, but not in their blind fields.

Summary: In this study, we investigated the modulation of auditory duration perception by task-irrelevant visual apparent motion. We found that the speed and temporal frequency of the apparent motion had an impact on the perception of auditory duration. Slow apparent motion led to overestimation of auditory duration, while fast apparent motion did not have this effect. Additionally, the temporal frequency of the apparent motion influenced auditory duration perception, with fast apparent motion and the actual motion frequency resulting in underestimation of auditory duration.

Summary: The primate superior colliculus plays a crucial role in small eye movements and visual processing, particularly at the foveal scale. It integrates visual and movement signals, regulates eye positioning and microeye movements, while also showing sensitivity enhancement and suppression effects in the periphery.

Summary: The study found that the intervention can reduce ipsilesional exploration bias in patients with spatial neglect, and similar effects were seen in healthy participants. Modifying the intervention method can impact the results, with the original version showing more significant and long-lasting effects. This intervention shows promise for successful application in treating patients with spatial neglect.
