Summary: Humans use different spatial reference frames for navigation with specific brain regions being activated. Environmental space shows stronger activation in certain brain regions compared to vista space, and allocentric reference frame also displays stronger activation in some areas.

Summary: The study found that alignment effects in spatial memory primarily stem from organization along reference directions rather than relation encoding. Data from both tasks indicated that only a single direction is encoded in memory.

Summary: This study compared the effective connectivity of dorsal pulvinar (dPul) and lateral intraparietal area (LIP) and found overlapping and distinct patterns of thalamocortical and corticocortical connections between the two regions, with LIP showing more extensive activation along the intraparietal sulcus. Task-specific correlations between spatial selectivity and stimulation effects were observed, and the modulation of task-related activity by stimulation was best fitted by an additive model scaled down by the initial response amplitude.

Summary: Performing working memory tasks require maintenance and transformation of information. Delay-period activity recorded from prefrontal neurons showed a gradual change from sensory to motor information during the delay period. Individual prefrontal neurons were found to encode and adjust cue directions by referencing retinotopic or saccade-based coordinate frames. Manipulating the reference frame allows for the transformation of visual-to-motor information.

Summary: Recently, memory-based methods have made remarkable progress in video object segmentation. However, their performance is still limited by error accumulation and redundant memory. To address these issues, we propose an efficient and effective segmentation method called IMSFR. It utilizes isogenous memory sampling and frame-relation mining to minimize the semantic gap and preserve contextual information. Extensive experiments show that IMSFR achieves state-of-the-art performance and exhibits strong robustness against frame sampling.

Summary: This study examined the object constancy abilities and object-picture recognition of goldfish by presenting them with photographs of plastic turtles and frogs at different viewing angles. The results showed that goldfish were able to successfully distinguish between the different photographs, demonstrating both viewpoint independence and viewpoint-dependent representations. The study also found that goldfish performed better with color photographs compared to black and white photographs, suggesting that they rely on color cues. Further research is needed to understand the conditions under which goldfish succeed in object constancy tasks and perceive photographs as representations of real-world objects.

Summary: The study found that children with autism spectrum disorder have poorer chunking abilities in spatial working memory but rely more on reference frames. Providing more clues or references may strengthen their adaptability, while guiding them to integrate information can improve basic cognitive processing efficiency.

Summary: This study investigated the factors causing individuals to switch their preferred spatial strategy in active and passive navigation by examining brain dynamics. Results showed that navigation involved specific brain areas and individuals' behaviors were influenced by the turning angle of paths.

Summary: The current understanding of cognitive development is based on the assumption that infants can individuate objects early on. However, the object-first account fails to explain empirical findings in object individuation tasks, while alternative explanations exist. This paper proposes that children initially think in terms of features and cannot individuate objects, but they can learn this ability through spatial indexicals. The paper also critically discusses two accounts of object cognition that do not rely on symbolic capacities.

Summary: Object constancy is a crucial mechanism in the human visual system that allows for invariant object recognition across different viewpoints. Research suggests that the ventral visual stream plays a role in processing various object stimuli and may contain regions sensitive to the orientation of objects in space. Experiments with stroke patients and fMRI studies with healthy participants demonstrate greater neuronal activity and specific activation patterns in certain brain regions for objects in demanding viewing conditions, highlighting the contributions of these areas to visual object constancy.

Summary: Serial dependence is a phenomenon where our perception is often attracted to what we have seen before. This study found that serial dependence is substantially modulated by the correspondence in relative coordinates, but not by that in absolute coordinates, suggesting that spatial correspondence in relative space plays a more effective role in maintaining stable perception in dynamic situations.

Summary: The study reveals that the transcriptional coregulator CtBP2 is specifically expressed in the dorsal CA3 region and regulates calcium permeable AMPA receptors through the CtBP2/GluR2 pathway, thereby affecting spatial reference memory.

Summary: Object size perception and neural representation are attracted towards recently viewed sizes, revealing effects on neural response preferences that may underlie context dependence of object size perception. This context-dependent object size representation shows that object size perception is influenced by the range of recently viewed object sizes.

Summary: Spatial cognitive abilities are crucial for foraging animals, and encoding the location of an object in relation to another object is essential for successful foraging. Bees predominantly use egocentric information to encode spatial information, but they exhibit an allocentric strategy in the context of relational similarity, suggesting that egocentric representations may not be evolutionary ancestral.

Summary: This article introduces a vision-based detection and spatial localization scheme for forest fires, developed on an unmanned aerial vehicle (UAV) with an OAK-D camera. The scheme includes a lightweight detector, NanoDet, for identifying and locating fires, as well as techniques for depth map calculation and coordinate conversion. Experimental results demonstrate that the system can effectively detect flame targets and meet precision requirements.

Summary: This study aimed to differentiate noise-induced hearing loss (NIHL) from age-related hearing loss by examining the characteristics of distortion product otoacoustic emissions (DPOAEs). The results showed that DPOAEs and DPOAE signal-to-noise ratios (SNRs) were correlated with age at all frequencies, and were correlated with both age and noise exposure at 2 kHz, 3 kHz, 4 kHz, and 6 kHz. The difference between DPOAE SNRs at 1 kHz and 3 kHz showed significant correlation with noise exposure but not with age.

Summary: This study investigates whether diabetes affects the daily rhythm of gene expression in the retina. The results show that diabetic mice exhibited phase advancement in the expression of certain genes compared to non-diabetic mice. The study also identified oxygen-sensing mechanisms and HIF1alpha as potential upstream regulators. These findings provide important insights into the development of diabetic retinopathy.

Summary: Visual stimuli presented around the time of a saccade can be perceived differently by the visual system, including a reduction in the harmful impact of flankers. This study investigated the effects of microsaccades on crowded stimuli placed 20 arc minutes from the center of gaze. The findings suggest two separate pre-saccadic benefits, one that regularizes the crowding zone and another that specifically benefits microsaccade targets surrounded by tangential flankers.

Summary: This study revealed that less than one-third of adults with normal binocular vision were able to successfully free-fuse random-dot image pairs and identify the embedded stereoscopic shapes. The successful participants showed a dissociation of vergence and accommodative responses, while the unsuccessful ones either exhibited strong vergence and accommodation or weak vergence and strong accommodation. Task performance of the unsuccessful cluster improved significantly with pharmacological paralysis of accommodation. A minority of participants also learned to dissociate one direction of their vergence and accommodation crosslinks with repeated free-fusion trials, optimizing their task performance.
