Contextual knowledge configures attentional control networks
NE DiQuattro, JJ Geng - Journal of Neuroscience, 2011 - Soc Neuroscience
Contextual cues are predictive and provide behaviorally relevant information; they are not
the main objective of the current task but can make behavior more efficient. Using fMRI, we …

Effective connectivity within the frontoparietal control network differentiates cognitive control and working memory
Cognitive control and working memory rely upon a common fronto-parietal network that

Frontoparietal representations of task context support the flexible control of goal-directed cognition
Cognitive control allows stimulus-response processing to be aligned with internal goals and
is thus central to intelligent, purposeful behavior. Control is thought to depend in part on the …
