Visualization of changes in presynaptic function during long-term synaptic plasticity

Zakharenko, Stanislav S., Zablow, Leonard, Siegelbaum, Steven A.·2001·Nature Neuroscience

Abstract

Controversy exists regarding the site of modification of synaptic transmission during long-term plasticity in the mammalian hippocampus. Here we used a fluorescent marker of presynaptic activity, FM 1-43, to directly image changes in presynaptic function during both short-term and long-term forms of plasticity at presynaptic boutons of CA3-CA1 excitatory synapses in acute hippocampal slices. We demonstrated enhanced presynaptic function during long-term potentiation (LTP) induced either chemically (with tetraethylammonium), or by high-frequency (200-Hz) electrical stimulation. Both of these forms of LTP required activation of L-type voltage-gated calcium channels and NMDA receptors in the postsynaptic CA1 neuron. These results thus implied that a long-lasting increase in the efficacy of synaptic transmission is likely to depend, at least in part, on enhanced transmitter release from the presynaptic neuron.

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

  • Destaining curves of FM1-43 were superimposable before and after tetanic induction of NMDAR-dependent LTP in CA1 neurons at 50-100 Hz.

    “Just as with MK-801, the destaining curves were superimposable before and after tetanic induction of NMDAR-dependent LTP in CA1 neurons at 50 -100 Hz (Zakharenko et al. 2001).”

  • At CA1 excitatory synapses, both NMDAR-dependent and NMDAR-independent forms of LTP can coexist under certain conditions.

    “There is even evidence that at CA1 excitatory synapses both NMDAR-dependent and NMDAR-independent forms of LTP can coexist under certain conditions (49–51).”

  • With intense induction protocols for LTP, a component of LTP requires the activation of VDCCs.

    “with intense induction protocols for LTP a component of LTP requires the activation of VDCCs (49–51, 193, 196).”

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.
