Summary: This study measured occipital activity in different spatial regions during the processing of visual displays and found that goal-directed attention and salience jointly modulate activity distribution in the occipital cortex, with involvement of multiple functional paths and interactions.

Summary: This study demonstrates that processing visuospatial information automatically activates the manual motor system, but the timing and direction of this effect vary depending on the type of stimulus.

Summary: This study found that processing visuospatial information automatically activates the manual motor system, but the effects vary depending on the type of stimulus. Lateralized objects and central arrows led to a larger increase of grip force in the ipsilateral hand, while words resulted in the opposite pattern.

Summary: The study found that statistical regularities and salience signals both modulate occipital activity in a spatially specific manner, but their integration into attentional processing priorities relies on dissociable brain mechanisms.

Summary: Conscious visual perception is associated with early processing in stimulus-specific sensory brain areas and occipitotemporal processes, while task-related processes lead to widespread brain activations, including late frontoparietal activity.

Summary: Covert attention, both endogenous and exogenous, improves performance by enhancing gain in all orientations without changing tuning width. In the spatial frequency dimension, endogenous attention enhances gain both above and below target frequency, whereas exogenous attention only enhances gain above. Exogenous attention also shifts peak sensitivity to frequencies above target, while endogenous attention does not.

Summary: This study demonstrates the similarity in mechanisms between visual and auditory spatial attention in the brain, using alpha power modulation for top-down suppression of distractors and its close relationship with oculomotor action.

Summary: Grain pest classification is important for grain storage and protection. This study addresses limitations in current research by collecting a high-quality dataset and proposing a novel triple-attention network (FcsNet) that achieves good performance in image classification.

Summary: This study utilized hybrid methods combining regional topographic models and residual kriging for mapping SOC density, evaluating the effects of different sampling designs on final map quality. Results indicated that spatial coverage sampling with close-pairs inclusions can generate maps with smaller variation in quality, while stratified random sampling can provide unbiased mean estimates for the area of interest.

Summary: The study explored visual-spatial and verbal remote associations through CRRAT and CCRAT, finding significant differences in brain mechanisms between the two types of associations. Different brain regions were activated during visual-spatial and verbal associations, indicating distinct cognitive processes involved in each.

Summary: The study found that reward cues can selectively modulate the Frontal Eye Field (FEF) during attentional shifts, especially after high-predictive cueing to invalid locations. Reward information also modulated FEF connectivity to superior colliculus, striatum, and visual cortex.

Summary: Working memory can flexibly store information based on behavioral goals. A study found that in a visual working memory task, there was less information about remembered spatial position in early visual and parietal regions when the required response was known, while a representation of the planned motor action emerged in primary somatosensory, primary motor, and premotor cortex.

Summary: Studies comparing exogenous and endogenous attention found that the latter is slower but sustained, and attention deployment takes longer at distant locations compared to nearby ones.

Summary: Person re-identification achieves higher accuracy by learning self-attention among different parts of a person's image. This approach uses CNN-based deep architectures and self-attention modules, combined with self-context mapping modules, to capture global associations in person images effectively.
