Abstract

Cholinergic neurons comprise a small population of cells in the striatum but have fundamental roles in fine tuning brain function, and in the etiology of neurological and psychiatric disorders such as Parkinson's disease (PD) or schizophrenia. The process of developmental cell specification underlying neuronal identity and function is an area of great current interest. There has been significant progress in identifying the developmental origins, commonalities in molecular markers, and physiological properties of the cholinergic neurons. Currently, we are aware of a number of key factors that promote cholinergic fate during development. However, the extent of cholinergic cell diversity is still largely underestimated. New insights into the biological basis of their specification indicate that cholinergic neurons may be far more diverse than previously thought. This review article, highlights the physiological features and the synaptic properties that segregate cholinergic cell subtypes. It provides an accurate picture of cholinergic cell diversity underlying their organization and function in neuronal networks. This review article, also discusses current challenges in deciphering the logic of the cholinergic cell heterogeneity that plays a fundamental role in the control of neural processes in health and disease.

  • Cholinergic neurons are found mainly in subclass 58 in the ventral PAL (11 clusters), but also include 2 clusters in LSX, 8 clusters in MH, 3 clusters in PPN, 5 clusters in DMX and NTS, and approximately 13 clusters scattered in other medulla nuclei.

    “Cholinergic neurons43,44 are found mainly in subclass 58 in the ventral PAL (11 clusters), but also include 2 clusters in LSX, 8 clusters in MH, 3 clusters in PPN, 5 clusters in dorsal motor nucleus of the vagus nerve (DMX) and nucleus of the solitary tract (NTS), and approximately 13 clusters scattered in other medulla nuclei.”

    The Introduction reports cholinergic neurons in the basal forebrain, medial habenula, and pedunculopontine nucleus, supporting some of the locations named. It does not give the claimed subclass designation or cluster counts, or establish the stated distribution across LSX, DMX, NTS, and other medulla nuclei. (LLM, conf=0.85)

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.
