Delay-Period Activity of the Parietal Cortex As a Representation of Context Binding Processes in Working Memory

This study further investigated the role of IPS in context-binding for spatial WM. Human subjects (n = 13) performed a dual-serial retro-cueing task (DSR) during fMRI scanning where content (location) and context (orientation) was manipulated. Results suggest that IPS is essential in processing context rather than representing task difficulties.
