    Functional integration of a serotonergic neuron in the Drosophila antennal lobe

    Xiaonan Zhang, Quentin Gaudry
    Serotonergic cells innervating the Drosophila antennal lobe are inhibited by odors and modulate olfactory responses in conjunction with the entire serotonergic network.
    1. Neuroscience

    A resource for the Drosophila antennal lobe provided by the connectome of glomerulus VA1v

    Jane Anne Horne, Carlie Langille ... Ian A Meinertzhagen
    FIB-SEM is used to identify comprehensively and reconstruct 192 neurons and their complete connectome for glomerulus VA1v of the Drosophila antennal lobe, in particular to reconstruct its local interneurons.

    Task-specific roles of local interneurons for inter- and intraglomerular signaling in the insect antennal lobe

    Debora Fusca, Peter Kloppenburg
    In the antennal lobe of insects, nonspiking local interneurons play a crucial role in intraglomerular signaling.
    1. Neuroscience

    Synaptic organization of the Drosophila antennal lobe and its regulation by the Teneurins

    Timothy J Mosca, Liqun Luo
    A comprehensive synapse-level analysis of a fly central-brain region has led to the identification of molecules that are necessary for mediating the normal density of connections.
    1. Neuroscience

    Projection neurons in Drosophila antennal lobes signal the acceleration of odor concentrations

    Anmo J Kim, Aurel A Lazar, Yevgeniy B Slutskiy
    Neurons in the fruit fly olfactory system respond most strongly to the sudden appearance of an odor, and to odors that are changing rapidly in strength, but are relatively insensitive to the absolute levels of an odor.

    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.

    Chronic exposure to odors at naturally occurring concentrations triggers limited plasticity in early stages of Drosophila olfactory processing

    Zhannetta V Gugel, Elizabeth G Maurais, Elizabeth J Hong
    Chronic stimulation with odors at naturally occurring concentrations only mildly impacts early stages of olfactory processing, suggesting a need to re-interpret prevailing models of how chronic odor exposure affects olfactory function.
    1. Neuroscience

    The wiring diagram of a glomerular olfactory system

    Matthew E Berck, Avinash Khandelwal ... Albert Cardona
    The complete neural circuit map of a tractable olfactory system will support studies towards bridging the gap between circuits and behavior.

    Unique neural coding of crucial versus irrelevant plant odors in a hawkmoth

    Sonja Bisch-Knaden, Michelle A Rafter ... Bill S Hansson
    The sense of smell of female hawkmoths has evolved to find the intense odor of floral nectar sources as well as inconspicuous scents of oviposition sites within a complex olfactory landscape.

    Tyramine and its Amtyr1 receptor modulate attention in honey bees (Apis mellifera)

    Joseph S Latshaw, Reece E Mazade ... Brian Smith
    Genetic variation in a biogenic amines receptor underlies a means of gain control for nonassociative learning and hence an important form of attention that is the basis for tradeoffs in foraging in a social collective.
