Attentional orienting to mnemonic representations: Reduction of load-sensitive maintenance-related activity in the intraparietal sulcus

► Attention-related reduction of BOLD response in posterior and anterior IPS. ► Data suggest that attention operates via reduction of unattended representations. ►A confound with expectation/anticipatory effects can be excluded. ► Selection efficiency is facilitated with sequential stimulus presentation. ► Functional subdivision in IPS according to attentional and mnemonic properties.
