Abstract

The neocortex contains a multitude of cell types that are segregated into layers and functionally distinct areas. To investigate the diversity of cell types across the mouse neocortex, here we analysed 23,822 cells from two areas at distant poles of the mouse neocortex: the primary visual cortex and the anterior lateral motor cortex. We define 133 transcriptomic cell types by deep, single-cell RNA sequencing. Nearly all types of GABA (γ-aminobutyric acid)-containing neurons are shared across both areas, whereas most types of glutamatergic neurons were found in one of the two areas. By combining single-cell RNA sequencing and retrograde labelling, we match transcriptomic types of glutamatergic neurons to their long-range projection specificity. Our study establishes a combined transcriptomic and projectional taxonomy of cortical cell types from functionally distinct areas of the adult mouse cortex.

  • The NP-CT-L6b-like subclasses emerge as a group highly distinct from the IT-ET-like subclasses, forming two distinct classes, IT-ET Glut and NP-CT-L6b Glut.

    “We also observed that the NP–CT–L6b-like (NP, near-projecting; CT, corticothalamic; L6b, layer 6b) subclasses emerge as a group highly distinct from the IT–ET-like (IT, intratelencephalic; ET, extratelencephalic) subclasses13,23,26,27, forming two distinct classes, IT–ET Glut and NP–CT–L6b Glut.”

    From A high-resolution transcriptomic and spatial atlas of cell types in the whole mouse brain (2023) · cites this paper as [26]

    In “Glutamatergic taxonomy by scRNA-seq and projections” (page unavailable), the paper identifies IT, near-projecting and CT as glutamatergic subclasses and describes L6b types. It does not report that NP–CT–L6b and IT–ET form two distinct classes; “Overall cell type taxonomy” instead uses “glutamatergic” as the class and “L6b” as a subclass. (LLM, conf=0.86)

  • Cortical GABAergic cell types are shared across all cortical areas.

    “One exception is cortical GABAergic cell types, which are shared across all cortical areas as we previously reported23,26”

    From A high-resolution transcriptomic and spatial atlas of cell types in the whole mouse brain (2023) · cites this paper as [26]

    The Abstract reports that nearly all GABAergic neuron types were shared between the two mouse neocortical areas studied, ALM and VISp. The Overall cell type taxonomy section identifies two VISp-specific exceptions. The claim overstates both the extent of sharing and the number of cortical areas examined. (LLM, conf=0.91)

  • Prediction of GABAergic subclasses and their spatial location in both directions appears to have more confusions, especially in the Subpallium-GABA neighbourhood, consistent with the more widespread distribution across multiple cortical areas of many GABAergic cell types.

    “Notably, the prediction of GABAergic subclasses and their spatial location in both directions appears to have more confusions, especially in the Subpallium-GABA neighbourhood, consistent with the more widespread distribution across multiple cortical areas of many GABAergic cell types23,26.”
  • Clustering for both 10xv2 and 10xv3 datasets was performed independently using in-house developed R package scrattch.bigcat.

    “Clustering for both 10xv2 and 10xv3 datasets was performed independently using the in-house developed R package scrattch.bigcat (v0.0.5, available via github https://github.com/AllenInstitute/scrattch.bigcat), which is a scaled-up version of R package scrattch.hicat23,26 to deal with the increased size of datasets.”
  • Loki Decompose was assessed on an in-house TNBC dataset, a human colorectal cancer dataset and a brain dataset.

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.
