Endogenous and Stimulus-driven Mechanisms of Task Control

Shulman, Gordon L, Corbetta, Maurizio·2004·Functional Neuroimaging of Visual Cognition

Abstract

While cognitive processes can be prepared to carry out pre-specified tasks, they must be sufficiently flexible to respond to new contingencies. We propose that this flexibility is achieved through the interaction of two sets of regions in the human brain. One set is concerned with the endogenous control of tasks and primarily involves dorsolateral prefrontal cortex, intraparietal sulcus (IPs), and frontal eye field (FEF). These regions are active during task preparation, generating signals for selecting task-relevant stimuli and linking them to responses, and maintain these signals during task performance. The other set is recruited by behaviorally important stimuli and involves the temporal–parietal junction (TPJ) and prefrontal cortex.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A functional interaction between the dorsal and ventral attention systems has been proposed such that task-relevant signals from the dorsal system filter stimulus-driven signals in the ventral system, whereas stimulus-driven circuit-breaking signals from the ventral system provide an interrupt to the dorsal system, reorienting it toward salient stimuli.

    “A functional interaction between the dorsal and ventral system has been proposed such that task-relevant signals from the dorsal system ''filter'' stimulus-driven signals in the ventral system, whereas stimulus-driven ''circuit-breaking'' signals from the ventral system provide an interrupt to the dorsal system, reorienting it toward salient stimuli (4,21).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
