Blockade of postsynaptic activity in sleep inhibits developmental plasticity in visual cortex

Frank, Marcos G., Jha, Sushil K., Coleman, Tammi·2006·NeuroReport

Abstract

Ocular dominance plasticity is enhanced by sleep and reduced by sleep deprivation or when all neural activity in the sleeping visual cortex is reversibly inhibited. These latter findings demonstrate that the mechanisms responsible for the effects of sleep on cortical plasticity are activity dependent. To better isolate this activity dependent mechanism, we investigated the role of postsynaptic activity by inactivating the sleeping visual cortex after a period of monocular deprivation with the gamma-amino-n-butyric acid agonist muscimol. Microelectrode recordings showed that ocular dominance plasticity was significantly reduced in cortices reversibly silenced during sleep compared with cortices infused with vehicle only. These findings demonstrate that postsynaptic activity during sleep is required for the consolidation of experience-dependent cortical plasticity.

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.
