    The activity-dependent histone variant H2BE modulates the life span of olfactory neurons

    Stephen W Santoro, Catherine Dulac
    A genome-organizing protein that is present only in the olfactory system of mice has been found to orchestrate changes in the relative numbers of different odor-sensing neurons on the basis of how active these neurons are.

    Opposite regulation of inhibition by adult-born granule cells during implicit versus explicit olfactory learning

    Nathalie Mandairon et al.
    While both implicit and explicit learning augment neurogenesis, adult-born cells differ in their morphology, functional coupling and inhibitory action impacting differentially the olfactory bulb output.

    Evolution of insect olfactory receptors

    Christine Missbach et al.
    Insect specific olfactory receptors are not an adaptation to a terrestrial insect lifestyle, but evolved later in insect evolution.

    Cooperative interactions enable singular olfactory receptor expression in mouse olfactory neurons

    Kevin Monahan et al.
    Biochemical and genetic experiments show that Ebf and Lhx2 cooperate to specify olfactory receptor enhancers, which cooperate to drive olfactory receptor expression.

    Variation in olfactory neuron repertoires is genetically controlled and environmentally modulated

    Ximena Ibarra-Soria et al.
    The neuronal composition of a mouse’s nose is individually unique due to a combination of olfactory experience and genetic variation local to olfactory receptor genes.

    The role of the NMD factor UPF3B in olfactory sensory neurons

    Kun Tan et al.
    The nonsense-mediated RNA decay (NMD) branch-specific factor UPF3B influences olfactory sensory neuron cell populations, the olfactory receptor repertoire, and antimicrobial gene expression.

    Temporal evolution of single-cell transcriptomes of Drosophila olfactory projection neurons

    Qijing Xie et al.
    Single-cell transcriptomes of Drosophila olfactory projection neurons correspond to previously defined cell types, exhibit unique characteristics at different developmental stages, and reveal cell-type-specific gene expression programs in development and function.
    1. Neuroscience

    Single-cell transcriptomes of developing and adult olfactory receptor neurons in Drosophila

    Colleen N McLaughlin et al.
    Single-cell transcriptomes of olfactory receptor neurons at multiple developmental stages reveal cell-type-specific gene expression programs that underlie their development and sensory biology.
    1. Neuroscience

    Semiochemical responsive olfactory sensory neurons are sexually dimorphic and plastic

    Aashutosh Vihani et al.
    Semiochemicals activate a subpopulation of sexually dimorphic olfactory sensory neurons.
    1. Neuroscience

    Feedback inhibition and its control in an insect olfactory circuit

    Subhasis Ray et al.
    Electrophysiological recordings and a large-scale biophysical model show that a unique inhibitory neuron plays a central role in structuring olfactory codes in the insect brain.
