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

    Jennie R Sims et al.
    The OSM-9 TRPV channel is differentially regulated due to developmental programming via modulation by TGF-β signaling, endogenous RNAi and chromatin remodeling pathways.

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

    Jenelle Wallace et al.
    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.

    The role of microglia and their CX3CR1 signaling in adult neurogenesis in the olfactory bulb

    Ronen Reshef et al.
    During adult neurogenesis in the olfactory bulb, microglia regulate the elimination (pruning), formation, and maintenance of synapses on newborn neurons, contributing to the functional integrity of the olfactory bulb circuitry.

    Embryonic and postnatal neurogenesis produce functionally distinct subclasses of dopaminergic neuron

    Elisa Galliano et al.
    In the mouse olfactory bulb, different types of local dopaminergic interneuron are produced before and after birth.

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

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

    The Natural History of Model Organisms: Advancing biology through a deeper understanding of zebrafish ecology and evolution

    David M Parichy
    The zebrafish is a premier model organism for biomedical research, with a rich array of tools and genomic resources, and combining these with a fuller appreciation of wild zebrafish ecology could greatly extend its utility in biological research.

    Point of View: Predictive regulation and human design

    Peter Sterling
    Why does the human regulatory system, which evolution tuned for small satisfactions, now constantly demand 'more'?

    The Natural History of Model Organisms: The secret lives of Drosophila flies

    Therese Ann Markow
    After decades of intensive research, D. melanogaster and its relatives could provide important tools for investigating future biological questions about human health and environmental change, but only if we better understand their natural history.
