Abstract

Diverse types of glutamatergic pyramidal neurons mediate the myriad processing streams and output channels of the cerebral cortex 1,2 , yet all derive from neural progenitors of the embryonic dorsal telencephalon 3,4 . Here we establish genetic strategies and tools for dissecting and fate-mapping subpopulations of pyramidal neurons on the basis of their developmental and molecular programs. We leverage key transcription factors and effector genes to systematically target temporal patterning programs in progenitors and differentiation programs in postmitotic neurons. We generated over a dozen temporally inducible mouse Cre and Flp knock-in driver lines to enable the combinatorial targeting of major progenitor types and projection classes. Combinatorial strategies confer viral access to subsets of pyramidal neurons defined by developmental origin, marker expression, anatomical location and projection targets. These strategies establish an experimental framework for understanding the hierarchical organization and developmental trajectory of subpopulations of pyramidal neurons that assemble cortical processing networks and output channels.

  • Lhx2 and Lhx9 are co-expressed in thalamus and midbrain glutamatergic types, but Lhx2 is also specifically expressed in pallium IT-ET types.

    “Lhx2 and Lhx9 are co-expressed in thalamus and midbrain glutamatergic types, but Lhx2 is also specifically expressed in the pallium IT–ET types108,109.”

    From A high-resolution transcriptomic and spatial atlas of cell types in the whole mouse brain (2023) · cites this paper as [108]

    The Fate-mapping PyN progenitors > RGs section (page unavailable) reports Lhx2-positive progenitors in the dorsal pallium that give rise to IT and ET neurons. It does not establish that Lhx2 is specifically expressed in the IT–ET neuron types themselves, and a search for Lhx9 found no passage about its co-expression with Lhx2 in thalamic or midbrain glutamatergic types.

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.
