    Encoding and control of orientation to airflow by a set of Drosophila fan-shaped body neurons

    Timothy A Currier, Andrew MM Matheson, Katherine I Nagel
    Electrophysiology identifies a population of fan-shaped body neurons that encode airflow in two directions relative to the fly midline and whose silencing disrupts proper orientation to airflow.

    Sleep homeostasis regulated by 5HT2b receptor in a small subset of neurons in the dorsal fan-shaped body of drosophila

    Yongjun Qian, Yue Cao ... Yi Rao
    Serotonergic signaling regulates sleep homeostasis through 5HT2b receptor in a small subset of neurons in the dorsal fan-shaped body in drosophila.

    Circuits that encode and guide alcohol-associated preference

    Kristin M Scaplen, Mustafa Talay ... Karla R Kaun
    Alcohol modifies dopaminergic microcircuits required for acquisition and expression of sensory memories in Drosophila resulting in a shift in behavioral response from malleable to inflexible.

    Transsynaptic mapping of Drosophila mushroom body output neurons

    Kristin M Scaplen, Mustafa Talay ... Karla R Kaun
    Transsynaptic mapping of the postsynaptic connections of mushroom body output neurons reveal both divergent and convergent projections allowing for multimodal integration prior to initiation of an output response.
    1. Neuroscience

    Differential regulation of the Drosophila sleep homeostat by circadian and arousal inputs

    Jinfei D Ni, Adishthi S Gurav ... Craig Montell
    Functional imaging and circuit mapping in the Drosophila brain identifies neuropils where sleep-promoting and arousal-promoting neuronal networks converge.

    Acute control of the sleep switch in Drosophila reveals a role for gap junctions in regulating behavioral responsiveness

    Michael Troup, Melvyn HW Yap ... Bruno van Swinderen
    Optogenetic activation reveals a larger role for the fly brain 'sleep switch' neurons in controlling both waking and sleeping behavioral responsiveness, partly via a parallel channel involving innexin6 electrical synapses.

    Neuronal reactivation during post-learning sleep consolidates long-term memory in Drosophila

    Ugur Dag, Zhengchang Lei ... Krystyna Keleman
    Consolidation of long-term courtship memory in Drosophila is mediated by a novel class of sleep promoting neurons that reactivates dopaminergic neurons engaged earlier in memory acquisition during post-learning sleep.
    1. Neuroscience

    Neural circuit mechanisms for transforming learned olfactory valences into wind-oriented movement

    Yoshinori Aso, Daichi Yamada ... Toshihide Hige
    A cluster of neurons that integrates inhibitory and excitatory synaptic inputs from the mushroom body output neurons of the appetitive and aversive memory compartments, respectively, triggers upwind steering, mediating memory-driven olfactory navigation behaviors.

    insomniac links the development and function of a sleep-regulatory circuit

    Qiuling Li, Hyunsoo Jang ... Nicholas Stavropoulos
    Spatiotemporal manipulations of insomniac reveal that this gene regulates the birth and development of sleep-regulatory neurons, enabling their proper function in adulthood.

    Extreme suction attachment performance from specialised insects living in mountain streams (Diptera: Blephariceridae)

    Victor Kang, Robin T White ... Walter Federle
    Net-winged midge larvae use suction organs covered in spine-like cuticular protrusions to generate powerful attachment on wet and rough surfaces.
