Abstract

Pheromone detection by the vomeronasal organ (VNO) is thought to rely on activation of specific receptors from the V1R and V2R gene families, but the central representation of pheromone receptor activation remains poorly understood. We generated transgenic mouse lines in which projections from multiple populations of VNO neurons, each expressing a distinct V1R, are differentially labeled with fluorescent proteins. This approach revealed that inputs from neurons expressing closely related V1Rs intermingle within shared, spatially conserved domains of the accessory olfactory bulb (AOB). Mitral cell-glomerular connectivity was examined by injecting intracellular dyes into AOB mitral cells and monitoring dendritic contacts with genetically labeled glomeruli. We show that individual mitral cells extend dendrites to glomeruli associated with different, but likely closely related, V1Rs. This organization differs from the labeled line of OR signaling in the main olfactory system and suggests that integration of information may already occur at the level of the AOB.

Claims other papers make about this one

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

  • Axons from VNO neurons expressing a given VR project to multiple glomeruli in the accessory olfactory bulb, where they form synaptic connections with AOB mitral/tufted cells, and AOB mitral cells form synapses within multiple glomeruli.

    “In turn, axons from VNO neurons expressing a given VR project to multiple glomeruli in the accessory olfactory bulb (AOB) (Belluscio et al., 1999; Rodriguez et al., 1999), where they form synaptic connections with AOB mitral/tufted cells, and AOB mitral cells form synapses within multiple glomeruli (Wagner et al., 2006).”
  • VNO neurons expressing a given VR project to multiple and spatially distributed glomeruli in the AOB, while AOB output neurons send dendrites to multiple glomeruli.

    “VNO neurons expressing a given VR project to multiple and spatially distributed glomeruli in the AOB, while AOB output neurons send dendrites to multiple glomeruli (Belluscio et al., 1999; Dulac and Torello, 2003; Wagner et al., 2006).”
  • The distributed non-topographic representation of each stimulus type mirrors the distributed organization in the AOB and suggests that information sorting may further be accomplished through selective projection to downstream regions.

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.
