Abstract

Cellular heterogeneity within the mammalian brain poses a challenge toward understanding its complex functions. Within the olfactory bulb, odor information is processed by subtypes of inhibitory interneurons whose heterogeneity and functionality are influenced by ongoing adult neurogenesis. To investigate this cellular heterogeneity and better understand adult-born neuron development, we utilized single-cell RNA sequencing and computational modeling to reveal diverse and transcriptionally distinct neuronal and nonneuronal cell types. We also analyzed molecular changes during adult-born interneuron maturation and uncovered developmental programs within their gene expression profiles. Finally, we identified that distinct neuronal subtypes are differentially affected by sensory experience. Together, these data provide a transcriptome-based foundation for investigating subtype-specific neuronal function in the olfactory bulb (OB), charting the molecular profiles that arise during the maturation and integration of adult-born neurons and how they dynamically change in an activity-dependent manner.

  • As immature OB neurons exit the RMS, they express markers such as Sox11 and S100a6, whereas mature OB neurons are marked by expression of Frmd7.

    “As the immature OB neurons exit the RMS, they express markers such as Sox11 and S100a687, whereas the mature OB neurons are marked by the expression of Frmd7.”

    From A high-resolution transcriptomic and spatial atlas of cell types in the whole mouse brain (2023) · cites this paper as [87]

    The Results section, “Transcriptome-Based Clustering of Neurons Identifies Markers of Neuronal Subtypes” (page unavailable), identifies Sox11-enriched cells in the rostral migratory stream as immature migrating adult-born neurons. It does not establish that they express Sox11 as they exit the stream; searches of our copy for S100a6 and Frmd7 found no support for those proposed markers. (LLM, conf=0.86)

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.
