Multiple gates on working memory
Open accessAbstract
The contexts for action may be only transiently visible, accessible, and relevant. The corticobasal ganglia (BG) circuit addresses these demands by allowing the right motor plans to drive action at the right times, via a BG-mediated gate on motor representations. A long-standing hypothesis posits these same circuits are replicated in more rostral brain regions to support gating of cognitive representations. Key evidence now supports the prediction that BG can act as a gate on the input to working memory, as a gate on its output, and as a means of reallocating working memory representations rendered irrelevant by recent events. These discoveries validate key tenets of many computational models, circumscribe motor and cognitive models of recurrent cortical dynamics alone, and identify novel directions for research on the mechanisms of higher-level cognition.

According to prominent neurocomputational models, a blunted phasic dopamine response should hinder gate opening.
“According to prominent neurocomputational models (Chatham & Badre, 2015; Frank et al., 2001; Hazy et al., 2006; O’Reilly, 2006), a blunted phasic response should hinder gate opening.”

In “Input gating of working memory” (page not available), the paper says Go-cell activity favors gate opening and working-memory updating, and reports updating deficits with dopamine depletion. It does not specifically say that a blunted phasic dopamine response would hinder gate opening. (LLM, conf=0.84)
Experimental — accuracy not yet measuredAccording to prominent neurocomputational models, the balance between maintenance and flexible updating in working memory is controlled by an input-gating mechanism that dynamically regulates access of input to working memory.
“According to prominent neurocomputational models (Chatham & Badre, 2015; Frank, Loughry, & O’Reilly, 2001; Hazy et al., 2006; O’Reilly, 2006), the balance between the functionally opposite states of robust maintenance and flexible updating is controlled by an input-gating mechanism, which dynamically regulates the access of input to WM.”

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.
