Abstract

Memory consolidation in the neocortex: Information transfer between brain structures located in the medial-temporal lobe and the neocortex is essential for learning. However, the neuronal underpinnings of this transfer are unknown. Doron et al. found that neurons located in the deep layers of the perirhinal cortex exhibit increased firing after microstimulation upon learning (see the Perspective by Donato). Learning was associated with the emergence of a small population of neurons in layer 5 of the somatosensory cortex that increased bursting upon stimulation. This increase in bursting was accompanied by an increase in dendritic activity, and silencing the perirhinal cortex to layer 1 projection effectively disrupted learning and its physiological correlates. During learning, perirhinal inputs thus act as a gate for the enhancement of cortico-cortical inputs, which are necessary for stimulus detection and are strengthened during learning.

  • RPT explains inattentional and change blindness, and why only a few visual items (held in WM) are reported after brief presentations with no cue.

    “This explains, e.g., inattentional and change blindness, and why only a few visual items (held in WM) are reported after brief presentations with no cue.108”

    The paper’s Abstract describes rodents learning to report electrical microstimulation of somatosensory cortex. Searches for inattentional blindness, change blindness, visual working memory, and uncued brief visual presentations found no passage addressing the claimed explanation. (LLM, conf=0.77)

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.
