The cholinergic mesopontine tegmentum is a relatively neglected nicotinic master modulator of the dopaminergic system: relevance to drugs of abuse and pathology

Abstract

The mammalian mesopontine tegmentum (MPT) contains two cholinergic nuclei, the pedunculopontine tegmental nucleus (PPTg) and the laterodorsal tegmental nucleus (LDTg). These provide the cholinergic innervation of, among other brain areas, the dopaminergic A9 and A10 cell groups. Their axons are thus the source of endogenous acetylcholine (ACh) acting on somato‐dendritic acetylcholine receptors in the substantia nigra (SN) and ventral tegmental area (VTA). The anatomy, physiology, functional and pathological implications of these interactions with the nicotinic subtype of acetylcholine receptors (nAChRs) are discussed with a view of the important role of the MPT as a master regulator of nicotinic dopaminergic signalling in the brain, including for nicotine addiction.

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

  • Both the PPTg and laterodorsal tegmental (LDTg) nuclei send cholinergic projections to the midbrain ventral tegmental area (VTA), where they activate nAChRs on both DA and non-DA neurons.

    “Both the PPTg and laterodorsal tegmental (LDTg) nuclei send cholinergic projections to the midbrain ventral tegmental area (VTA), where they activate nAChRs on both DA and non-DA neurons [40].”

  • PPT/LDT cholinergic afferents influence DA neurons via nAChRs.

    “In addition, the PPT/LDT cholinergic afferents have important endogenous influences over DA neurons by acting via nAChRs (Maskos 2008, 2010).”

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.
