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

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.

The paper shows that categorical coding of color stimuli occurs in extrastriate visual cortex during working memory, not perception.

The paper investigates whether working memory signals in early visual cortex depend on visual imagery, finding that reconstruction quality is similar for strong and weak imagers.
