Hibernation-induced structural changes in synaptic contacts between mossy fibres and hippocampal pyramidal neurons

Popov, V.I., Bocharova, L.S.·1992·Neuroscience

Abstract

Mossy fibre synapses on the CA3 hippocampal neurons in the brain of ground squirrels repeatedly undergo a striking structural transformation during hibernation. In the middle of hibernation bout the giant complex mossy fibre synapses have a reduced number of dendritic spine infoldings that are smaller and have a decreased number of postsynaptic densities in comparison with mossy fibre synapses of active animals. Two hours after arousal all these parameters of mossy fibre synapses increase and significantly exceed their levels not only in torpid but in active euthermic animals between bouts of torpor. The longer postsynaptic densities and the greater proportion of perforated postsynaptic densities were found soon after arousal. These rapid, reversible and repeated changes indicate a cyclic process of partial denervation/reinnervation of hippocampal neurons by mossy fibres in the course of the innate, stereotyped behaviour.

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.
