Visuospatial working memory is cortically enabled through veridical, categorical and semantic representations

The paper shows that visual working memory uses different cortical representations, including categorical, semantic, and spatial formats, across multiple brain regions.

Sensory modality- and load-dependent changes across cortical representations for working memory storage

The paper shows that increasing visual load during working memory tasks reduces decodable information in visual cortex but not as much in frontoparietal areas, suggesting shared labor between these regions.

Dynamic regulation of neural variability during working memory reflects dopamine, functional integration, and decision-making

This study examines how neural variability during working memory is regulated by dopamine, functional integration, and decision-making using PET and fMRI data.

Effects of non-invasive brain stimulation on visual perspective taking: A meta-analytic study

This study meta-analyzes the effects of non-invasive brain stimulation on visual perspective taking, finding small effects and no strong evidence for higher-level mental rotation tasks.
