Postsynaptic signaling during plasticity of dendritic spines

Open access
Murakoshi, Hideji, Yasuda, Ryohei·2012·Trends in Neurosciences

Abstract

Dendritic spines, small bulbous postsynaptic compartments emanating from neuronal dendrites, have been thought to serve as basic units of memory storage. Despite their small size (~0.1 femtoliter), thousands of species of proteins exist in the spine, including receptors, channels, scaffolding proteins and signaling enzymes. Biochemical signaling mediated by these molecules leads to morphological and functional plasticity of dendritic spines, and ultimately learning and memory in the brain. Here, we review new insights into the mechanisms underlying spine plasticity brought about by recent advances in imaging techniques to monitor molecular events in single dendritic spines. The activity of each protein displays a specific spatiotemporal pattern, coordinating downstream events at different microdomains to change the function and morphology of dendritic spines.

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.
