    Microglial depletion disrupts normal functional development of adult-born neurons in the olfactory bulb

    Jenelle Wallace, Julia Lord ... Venkatesh N Murthy
    Adult-born neurons in the olfactory bulb that develop in the absence of microglia have a higher density of small spines but weaker excitatory inputs and reduced responses to sensory stimuli.

    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.

    Developmental programming modulates olfactory behavior in C. elegans via endogenous RNAi pathways

    Jennie R Sims, Maria C Ow ... Sarah E Hall
    The OSM-9 TRPV channel is differentially regulated due to developmental programming via modulation by TGF-β signaling, endogenous RNAi and chromatin remodeling pathways.

    Axon tension regulates fasciculation/defasciculation through the control of axon shaft zippering

    Daniel Šmít, Coralie Fouquet ... Alain Trembleau
    Competition between adhesive and tensile forces regulates axon fasciculation, thus introducing a new role of mechanical tension in the development of neural networks.

    Embryonic and postnatal neurogenesis produce functionally distinct subclasses of dopaminergic neuron

    Elisa Galliano, Eleonora Franzoni ... Matthew S Grubb
    In the mouse olfactory bulb, different types of local dopaminergic interneuron are produced before and after birth.

    Sox10-dependent neural crest origin of olfactory microvillous neurons in zebrafish

    Ankur Saxena, Brian N Peng, Marianne E Bronner
    Sensory neurons in the olfactory system develop from two different regions of the ectoderm, the olfactory placode and the cranial neural crest, whereas sensory neurons within the eye and ear develop from just one region.

    Presynaptic developmental plasticity allows robust sparse wiring of the Drosophila mushroom body

    Najia A Elkahlah, Jackson A Rogow ... E Josephine Clowney
    Sensory innervation density in the insect associative learning center is set by postsynaptic cells and accomplished by flexible allocation of processes by presynaptic cells.

    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.

    Tuning of delta-protocadherin adhesion through combinatorial diversity

    Adam J Bisogni, Shila Ghazanfar ... David M Lin
    Combinatorial expression patterns of δ-Pcdhs are defined within single neurons, and in vitro assays are employed to establish guiding principles used by this gene family to mediate cell adhesion.

    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.
