Dissecting the Components of Long-Term Potentiation
Open accessAbstract
The formation of memories relies in part on plastic changes at synapses between neurons. Although the mechanisms of synaptic plasticity have been studied extensively over several decades, many aspects of this process remain controversial. The cellular locus of expression of long-term potentiation (LTP), a major form of synaptic plasticity, is one of the most important unresolved phenomena. In this article, some recent advances in this area made possible by the development of new imaging tools are summarized. These studies have demonstrated that LTP is compound in nature and consists of both presynaptic and postsynaptic components. Some features of presynaptic and postsynaptic changes during compound LTP are also reviewed.

LTP is compound in nature, involving both increased presynaptic release probability and enhanced postsynaptic conductance.
“However, evidence indicates that LTP is compound in nature, involving both increased presynaptic release probability and enhanced postsynaptic conductance [65].”
From Molecular Physiology of the Neuronal Synapse (2026) · cites this paper as [65]
The section “A summary of LTP mechanisms” describes compound LTP at CA3–CA1 synapses as having presynaptic and postsynaptic components, with their contributions depending on the stimulation protocol. The section “The evolution of fluorescent probes of presynaptic activity” reports more effective neurotransmitter release after compound LTP. Our copy does not establish that the presynaptic change specifically increases release probability or that the postsynaptic change specifically enhances conductance. (LLM, conf=0.83)

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.
