Abstract

Nicotinic acetylcholine receptors (nAChRs) are widely expressed throughout the central nervous system and participate in a variety of physiological functions. Recent advances have revealed roles of nAChRs in the regulation of synaptic transmission and synaptic plasticity, particularly in the hippocampus and midbrain dopamine centers. In general, activation of nAChRs causes membrane depolarization and directly and indirectly increases the intracellular calcium concentration. Thus, when nAChRs are expressed on presynaptic membranes their activation generally increases the probability of neurotransmitter release. When expressed on postsynaptic membranes, nAChR-initiated calcium signals and depolarization activate intracellular signaling mechanisms and gene transcription. Together, the presynaptic and postsynaptic effects of nAChRs generate and facilitate the induction of long-term changes in synaptic transmission. The direction of hippocampal nAChR-mediated synaptic plasticity - either potentiation or depression - depends on the timing of nAChR activation relative to coincident presynaptic and postsynaptic electrical activity, and also depends on the location of cholinergic stimulation within the local network. Therapeutic activation of nAChRs may prove efficacious in the treatment of neuropathologies where synaptic transmission is compromised, as in Alzheimer's or Parkinson's disease.

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • A sign switch of synaptic plasticity, necessary in the D network when the target remains real during the REM phase, was experimentally observed by the action of acetylcholine and is also involved in the regulation of REM sleep.

    “A sign switch of synaptic plasticity (necessary in the D network when the target remains real during the REM phase) was experimentally observed by the action of acetylcholine [36] and is also involved in the regulation of REM sleep [19].”
  • An important role for both nicotinic and muscarinic acetylcholine receptors has been defined in hippocampal synaptic plasticity.

    “An important role for both nAChRs and mAChRs has been defined in hippocampal synaptic plasticity (reviewed in (Giocomo and Hasselmo, 2007; McKay et al., 2007)) and these effects are mediated through intracellular signaling pathways downstream of mAChRs and nAChRs (reviewed in (Berg and Conroy, 2002; Cancela, 2001; Lanzafame et al., 2003; Rathouz et al., 1996)).”

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.
