Short-term forms of presynaptic plasticity

Abstract

Synapses exhibit several forms of short-term plasticity that play a multitude of computational roles. Short-term depression suppresses neurotransmitter release for hundreds of milliseconds to tens of seconds; facilitation and post-tetanic potentiation lead to synaptic enhancement lasting hundreds of milliseconds to minutes. Recent advances have provided insight into the mechanisms underlying these forms of plasticity. Vesicle depletion, as well as inactivation of both release sites and calcium channels, contribute to synaptic depression. Mechanisms of short-term enhancement include calcium channel facilitation, local depletion of calcium buffers, increases in the probability of release downstream of calcium influx, altered vesicle pool properties, and increases in quantal size. Moreover, there is a growing appreciation of the heterogeneity of vesicles and release sites and how they can contribute to use-dependent plasticity.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Short-term synaptic plasticity can increase or decrease the strength of a synaptic signal several-fold.

    “Short-term synaptic plasticity can increase or decrease the strength of a synaptic signal several-fold (Fioravante and Regehr, 2011).”

    From The Presynaptic Active Zone (2012) · cites this paper as Fioravante and Regehr, 2011

    The Introduction (page not specified) says short-term plasticity can either reduce or enhance synaptic strength. It does not quantify those changes as several-fold, so the magnitude in the citing sentence is unsupported by our copy. (LLM, conf=0.84)

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.
