The Cognitive Neuroscience of Working Memory
Open accessAbstract
For more than 50 years, psychologists and neuroscientists have recognized the importance of a working memory to coordinate processing when multiple goals are active and to guide behavior with information that is not present in the immediate environment. In recent years, psychological theory and cognitive neuroscience data have converged on the idea that information is encoded into working memory by allocating attention to internal representations, whether semantic long-term memory (e.g., letters, digits, words), sensory, or motoric. Thus, information-based multivariate analyses of human functional MRI data typically find evidence for the temporary representation of stimuli in regions that also process this information in nonworking memory contexts. The prefrontal cortex (PFC), on the other hand, exerts control over behavior by biasing the salience of mnemonic representations and adjudicating among competing, context-dependent rules. The “control of the controller” emerges from a complex interplay between PFC and striatal circuits and ascending dopaminergic neuromodulatory signals.

For short forms of memory, often referred to as working memory, information is stored by ongoing activity in neuronal networks.
“There is compelling evidence that for short forms of memory, often referred to as working memory, information is stored by ongoing activity in neuronal networks (1–4).”
From Synaptic memory and CaMKII (2023) · cites this paper as [2]
In “Working memory at the systems level,” the paper describes persistent neural activity during working-memory delays as evidence for maintaining representations. But the same section says persistent activity may not be necessary and discusses storage through short-term changes in synaptic weights. The claim overstates the paper’s position by presenting ongoing activity as the storage mechanism without that qualification. (LLM, conf=0.87)

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.
