    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.

    Origin of wiring specificity in an olfactory map revealed by neuron type–specific, time-lapse imaging of dendrite targeting

    Kenneth Kin Lam Wong, Tongchao Li ... Liqun Luo
    Advanced genetics and imaging reveal wiring logic underlying the olfactory map organization in the developing fruit fly brain, and strategies employed by projection neurons to target dendrites to specific locations in a timely manner.

    Evolution of insect olfactory receptors

    Christine Missbach, Hany KM Dweck ... Ewald Grosse-Wilde
    Insect specific olfactory receptors are not an adaptation to a terrestrial insect lifestyle, but evolved later in insect evolution.
    1. Neuroscience

    Semiochemical responsive olfactory sensory neurons are sexually dimorphic and plastic

    Aashutosh Vihani, Xiaoyang Serene Hu ... Hiroaki Matsunami
    Semiochemicals activate a subpopulation of sexually dimorphic olfactory sensory neurons.

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

    Qijing Xie, Maria Brbic ... Hongjie Li
    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.

    Cooperative interactions enable singular olfactory receptor expression in mouse olfactory neurons

    Kevin Monahan, Ira Schieren ... Stavros Lomvardas
    Biochemical and genetic experiments show that Ebf and Lhx2 cooperate to specify olfactory receptor enhancers, which cooperate to drive olfactory receptor expression.

    The role of the NMD factor UPF3B in olfactory sensory neurons

    Kun Tan, Samantha H Jones ... Miles F Wilkinson
    The nonsense-mediated RNA decay (NMD) branch-specific factor UPF3B influences olfactory sensory neuron cell populations, the olfactory receptor repertoire, and antimicrobial gene expression.
    1. Neuroscience

    Feedback inhibition and its control in an insect olfactory circuit

    Subhasis Ray, Zane N Aldworth, Mark A Stopfer
    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.
    1. Neuroscience

    Most primary olfactory neurons have individually neutral effects on behavior

    Tayfun Tumkaya, Safwan Burhanudin ... Adam Claridge-Chang
    Of the 50 primary olfactory channels in vinegar flies, only 10 drive avoidance or approach behavior when activated by themselves, indicating that most olfactory responses are multi-channel responses that follow complex combination rules.
    1. Neuroscience

    Chemoreceptor co-expression in Drosophila melanogaster olfactory neurons

    Darya Task, Chun-Chieh Lin ... Christopher J Potter
    Olfactory neurons of insects, once thought to express only a single type of olfactory receptor, exhibit widespread co-expression of receptors from multiple chemosensory gene families.
