The cholinergic system and hippocampal plasticity

Drever, Benjamin D., Riedel, Gernot, Platt, Bettina·2011·Behavioural Brain Research

Abstract

Acetylcholine is an essential excitatory neurotransmitter in the central nervous system and undertakes a vital role in cognitive function. Consequently, there is ample evidence to suggest the involvement of both nicotinic and muscarinic acetylcholine receptors in the modulation of synaptic plasticity, which is believed to be the molecular correlate of learning and memory. In the hippocampus in particular, multiple subtypes of both nicotinic and muscarinic receptors are present at presynaptic and postsynaptic loci of both principal neurons and inhibitory interneurons, where they exert profound bi-directional influences on synaptic transmission. Further evidence points to a role for cholinergic activation in the induction and maintenance of synaptic plasticity, and key influences on hippocampal network oscillations. The present review examines these multiple roles of acetylcholine in hippocampal plasticity.

Claims other papers make about this one

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

  • Nicotinic and muscarinic acetylcholine receptors on both GABAergic and glutamatergic neurons in the hippocampus can alter the subsequent response to excitatory inputs.

    “it is clear that nAChRs and mAChRs on both GABAergic and glutamatergic neurons in the hippocampus can alter the subsequent response to excitatory inputs (Drever et al., 2011).”
  • Cholinergic inputs to the hippocampus from the medial septum and the diagonal band of Broca impinge on both glutamatergic and GABAergic neurons throughout the structure.

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.
