[HTML][HTML] Working memory representations in visual cortex mediate distraction effects
Although the contents of working memory can be decoded from visual cortex activity, these
representations may play a limited role if they are not robust to distraction. We used model …

Flexible coding of visual working memory representations during distraction
Visual working memory (VWM) recruits a broad network of brain regions, including
prefrontal, parietal, and visual cortices. Recent evidence supports a “sensory recruitment” …

A matter of availability: sharper tuning for memorized than for perceived stimulus features
Our visual environment is relatively stable over time. An optimized visual system could
capitalize on this by devoting less representational resources to objects that are physically …
