Summary: Grouping by common fate plays an important role in how human observers perceive environmental objects. This study found that younger adults outperformed older adults in utilizing common fate to perceive objects. It was also observed that age systematically affects the ability of older adults to detect and visually perceive objects defined by common fate.

Summary: Smooth eye movements are essential for natural visual processes, and they can be guided by both visual cues and extraretinal signals. This study focuses on how the brain processes and integrates these signals during smooth pursuit eye movements. The researchers investigate the responses of neurons in the MSTd area of rhesus monkeys and find that most neurons have preferences for the direction of eye rotation based on both visual and extraretinal signals. This suggests that area MSTd plays a crucial role in integrating these signals and representing the velocity of smooth eye movements.

Summary: Recent studies have found a central tendency in the perception of physical features, but this does not apply to heading perception. However, perceived headings are generally biased towards the left side.

Summary: The method aims to estimate the depth of dynamic scenes from ordinary videos using a new test-time training framework, which recursively unrolls the scene-flow prediction MLP to impose local smooth motion priors and multi-view consistency constraints, resulting in accurate and coherent results.

Summary: Human heading perception is accurate for directions close to the straight-ahead, but systematic biases emerge in the periphery. A weak-to-moderate overrepresentation of peripheral headings in the MSTd model demonstrated high accuracy and precision. Physiological tuning characteristics play a crucial role in shaping the accuracy and precision of neural heading signals.

Summary: The study revealed that patients with Parkinson's disease showed lower accuracy in vestibular perception compared to healthy controls, but significant improvement was observed after deep brain stimulation treatment. However, there were no significant differences in visual heading perception between patients and controls.

Summary: This study explores the unsupervised learning of depth from monocular videos using photometric errors and introduces outlier masking technique and efficient weighted multi-scale scheme to improve the accuracy of depth learning. Extensive experiments demonstrate the effectiveness of the proposed approach on depth or ego-motion estimation, as well as separate evaluation on dynamic objects and static background regions for both supervised and unsupervised methods.

Summary: Psychophysical studies have found that heading perception from optic flow involves perceptual and post-perceptual stages, including working memory. This study examined the involvement of working memory in heading perception by recording scalp EEG while participants performed a heading perception task. The results showed that previous headings could be decoded from the EEG data when the blank display was presented, indicating the involvement of working memory in heading perception.

Summary: Multi-sensory decision making (MSDM) is crucial for making accurate decisions in complex environments. Recent research in computational theory, psychophysical behavior, and neurophysiology has made significant progress in understanding MSDM. By studying a visuo-vestibular heading model system, researchers have uncovered the complex temporal dynamics of vestibular signals in various brain regions, challenging the brain's ability to integrate cues across time and sensory modalities. Moreover, new evidence from higher-level decision-related areas has revised our understanding of how signals from different sensory modalities are processed and accumulated to form a unified perceptual decision.

Summary: This study reexamined the serial dependence in heading perception and found that it occurs at both perceptual and postperceptual stages. The results also showed that observers can optimally combine their perceptual observations and prior information to estimate heading.

Summary: The proposed backprojection-based SAR processing approach allows for fast and accurate imaging of moving objects and stationary background. By utilizing two algorithms, the method is able to efficiently detect moving objects, estimate their positions and velocities, and overlay their focused images over the stationary background. The approach demonstrates a tradeoff between complexity and performance, with a full 4-D phase space imaging algorithm optimized for low signal-to-clutter conditions and an adaptive detection and imaging algorithm reducing complexity in more favorable scenarios.

Summary: When interacting with the dynamic world, the brain compensates for neural delays in processing moving objects by predictively encoding their past trajectories. However, delays still accumulate in later stages of cortical processing. This was demonstrated in a study using high temporal resolution electroencephalographic data, which tracked neural position representations of moving objects at different stages of visual processing.

Summary: This paper introduces a new compressed data structure ContaCT for storing trajectories of moving objects, which enables constant-time access to compressed trajectories. Experimental results show that ContaCT outperforms the MVR-tree and compressed representation in terms of space occupancy and time performance.

Summary: The study found that microsaccadic characteristics, such as duration, peak velocity, and rate, were significantly modulated by optic flow stimuli and trial sequence. In standing conditions, microsaccades showed non-uniform directions in the upper-left quadrant of the visual field, while in sitting conditions, the directions were uniform. Additionally, microsaccade rate increased from trial 1 to trial 5 in all conditions.
