Abstract

Sleep is thought to consolidate changes in synaptic strength, but the underlying mechanisms are unknown. We investigated the cellular events involved in this process during ocular dominance plasticity (ODP)-a canonical form of in vivo cortical plasticity triggered by monocular deprivation (MD) and consolidated by sleep via undetermined, activity-dependent mechanisms. We find that sleep consolidates ODP primarily by strengthening cortical responses to nondeprived eye stimulation. Consolidation is inhibited by reversible, intracortical antagonism of NMDA receptors (NMDARs) or cAMP-dependent protein kinase (PKA) during post-MD sleep. Consolidation is also associated with sleep-dependent increases in the activity of remodeling neurons and in the phosphorylation of proteins required for potentiation of glutamatergic synapses. These findings demonstrate that synaptic strengthening via NMDAR and PKA activity is a key step in sleep-dependent consolidation of ODP.

  • Muscimol and zolpidem impair sleep-dependent plastic changes in visual cortex in cats, suggesting GABA plays critical role for plastic processes during sleep.

    “Conversely, the GABA A agonist muscimol and also zolpidem impaired sleep-dependent plastic changes in the visual cortex in a developmental model of synaptic plasticity in cats [i.e., ocular dominance plasticity (ODP); see sect.VIIA3 for details] (48,411,1059), suggesting that GABA plays a critical role for plastic processes occurring during sleep.”

    From About Sleep's Role in Memory (2013) · cites this paper as [48]

    The Results section (‘Sleep enhances ODP’; page unavailable) confirms sleep-dependent visual-cortex plasticity in cats. But this paper tests the NMDA-receptor antagonist APV and the PKA inhibitor Rp-8-Cl-cAMPS, not muscimol or zolpidem. Its References list a separate zolpidem study; our copy does not establish the claimed GABA mechanism. (LLM, conf=0.82)

  • Of zaleplon, eszopiclone, zolpidem, and triazolam, only zolpidem impaired sleep-dependent ODP, although all reduced REM sleep and increased non-REM sleep.

    “Of the GABA A agonistic substances zaleplon, eszopiclone, zolpidem, and triazolam, only zolpidem impaired sleep-dependent ODP, although all substances distinctly reduced REM sleep and increased non-REM sleep (48,1059).”

    From About Sleep's Role in Memory (2013) · cites this paper as [48]

    The Results (Experiment 1; page unavailable) say that hypnotic drugs profoundly inhibited post-deprivation REM sleep without impairing ODP. The References list a study titled “The non-benzodiazepine hypnotic Zolpidem impairs sleep-dependent cortical plasticity.” Our copy does not establish the four-drug comparison or that all four increased non-REM sleep. (LLM, conf=0.79)

  • These sleep-dependent changes are prevented by blocking NMDA receptors or PKA during sleep after monocular experience.

  • The beneficial effect of sleep on consolidation of ODP mainly strengthens cortical responses to stimulation of the nondeprived eye.

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.
