Integration of diverse information in working memory within the frontal lobe

Prabhakaran, V., Narayanan, K., Zhao, Z., Gabrieli, J. D. E.·2000·Nature Neuroscience

Abstract

Ability to integrate diverse forms of information in current thought, or working memory, is essential for human reasoning and problem solving. We used functional imaging to identify brain regions preferentially involved in maintaining integrated versus unintegrated information in working memory. For equal amounts of verbal and spatial information, activation of prefrontal cortex was greater for maintaining integrated rather than unintegrated representations. Posterior brain regions showed the opposite pattern. These results demonstrate frontal-lobe specialization in maintaining working-memory representations that integrate verbal and spatial information. The role of prefrontal cortex in integrating multiple forms of information in working memory may underlie its unique contribution to high-level cognition that demands flexible mental representations.

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?

  • ADHD is associated with underdevelopment or hypoactivation in right frontal/prefrontal and temporoparietal regions thought to support cross-modality binding in adults.

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.
