Shrinkage of Dendritic Spines Associated with Long-Term Depression of Hippocampal Synapses
Open accessAbstract
Activity-induced modification of neuronal connections is essential for the development of the nervous system and may also underlie learning and memory functions of mature brain. Previous studies have shown an increase in dendritic spine density and/or enlargement of spines after the induction of long-term potentiation (LTP). Using two-photon time-lapse imaging of dendritic spines in acute hippocampal slices from neonatal rats, we found that the induction of long-term depression (LTD) by low-frequency stimulation is accompanied by a marked shrinkage of spines, which can be reversed by subsequent high-frequency stimulation that induces LTP. The spine shrinkage requires activation of NMDA receptors and calcineurin, similar to that for LTD. However, spine shrinkage is mediated by cofilin, but not by protein phosphatase 1 (PP1), which is essential for LTD, suggesting that different downstream pathways are involved in spine shrinkage and LTD. This activity-induced spine shrinkage may contribute to activity-dependent elimination of synaptic connections.

“Conversely, the triggering of LTD is associated with the shrinkage of dendritic spines and perhaps even their disappearance (Na ¨gerl et al. 2004;Zhou et al. 2004;Wang et al. 2007;Kasai et al. 2010).”

In the citing paper
“In contrast, when two cells co-activate infrequently, dendritic spines shrink or disappear, and the synaptic connection weakens and is likely to be eliminated.(64, 65)”

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.
