Abstract

Cortical development involves synaptic formation and elimination. Although synaptogenesis predominates in the early stages and pruning in the later stages, the two processes are thought to happen concurrently. In adults, synaptic strength is modulated by behavioral state, and we asked whether synaptic remodeling may be affected by sleep and waking states. Using two-photon microscopy in adolescent mice, we found that waking results in a net increase in cortical spines, whereas sleep is associated with net spine loss.

  • In juvenile mice in vivo, two-photon microscopy in the sensorimotor cortex revealed a net decrease in spine growth across periods of sleep, although significant spine growth also occurred.

  • The mechanisms mediating synaptic plasticity during critical periods differ in essential aspects from those during later life, and differences in regulation of synaptic plasticity may still exist between juveniles and adults.

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.
