The roles of perineuronal nets and the perinodal extracellular matrix in neuronal function
Abstract
Perineuronal nets (PNNs) are extracellular matrix (ECM) chondroitin sulfate proteoglycan (CSPG)-containing structures that surround the soma and dendrites of various mammalian neuronal cell types. PNNs appear during development around the time that the critical periods for developmental plasticity end and are important for both their onset and closure. A similar structure - the perinodal ECM - surrounds the axonal nodes of Ranvier and appears as myelination is completed, acting as an ion-diffusion barrier that affects axonal conduction speed. Recent work has revealed the importance of PNNs in controlling plasticity in the CNS. Digestion, blocking or removal of PNNs influences functional recovery after a variety of CNS lesions. PNNs have further been shown to be involved in the regulation of memory and have been implicated in a number of psychiatric disorders.

In the citing paper
“PNNs form preferentially around fast-spiking parvalbumin (PV)+ GABAergic interneurons throughout the brain during the closure of the critical period of plasticity, effectively “locking” proximal synapses in place and providing synaptic stability [21] soon after synaptic pruning is completed by developmental microglia [22].”
From Microglia facilitate loss of perineuronal nets in the Alzheimer's disease brain (2020) · cites this paper as [21]
In the citing paper
“Although contrasting effects of PNN ablation on certain (specifically object recognition) memory tasks and measures of plasticity suggest this is not the case for all types of memory [21, 29, 87], such differences may also be at least partly attributable to the PNN ablation method utilized (e.g. enzymatic digestion vs genetic deletion of PNN components) which can produce differential effects on”

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.
