Muscarinic receptor activation facilitates the induction of long-term potentiation (LTP) in the rat dentate gyrus

Burgard, Edward C., Sarvey, John M.·1990·Neuroscience Letters

Abstract

Bath application of two different concentrations of muscarine produced two different effects on evoked responses in the dentate gyrus of rat hippocampal slices. A concentration of 1 microM muscarine did not affect the evoked population spike or excitatory postsynaptic potential (EPSP), but facilitated the induction of LTP. In contrast, a concentration of 10 microM muscarine depressed both the population spike and EPSP, but had no effect on LTP induction. The M1 muscarinic receptor antagonist pirenzepine (1 microM) blocked the muscarine-induced facilitation of LTP, but had no effect on the depression of evoked responses. These data suggest that activation of M1 receptors can facilitate the induction of LTP.

  • The enhancement of long-term encoding could be at least partially mediated by the cholinergic enhancement of long-term potentiation in the hippocampus.

    “The enhancement of long-term encoding could be at least partially mediated by the cholinergic enhancement of long-term potentiation in the hippocampus (Blitzer et al., 1990; Burgard and Sarvey, 1990; Auerbach and Segal, 1994; Isaac et al., 2009).”

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.
