    Shared mushroom body circuits underlie visual and olfactory memories in Drosophila

    Katrin Vogt et al.
    One memory center in the fly brain processes distinct appetitive and aversive associative memories of olfactory and visual cues using shared local circuits.

    Temporally specific engagement of distinct neuronal circuits regulating olfactory habituation in Drosophila

    Ourania Semelidou et al.
    Habituation to brief olfactory stimulation is biphasic and mediated by distinct neuronal circuits where an initial latency phase is rapidly followed by stimulus devaluation signifying behavioral habituation in Drosophila.

    Distinct lateral inhibitory circuits drive parallel processing of sensory information in the mammalian olfactory bulb

    Matthew A Geramita et al.
    Distinct lateral inhibitory circuits affect spiking in olfactory bulb mitral and tufted cells differently, which ultimately allows each cell type to best discriminate between similar odors in separate concentration ranges.

    Functional divergence of Plexin B structural motifs in distinct steps of Drosophila olfactory circuit assembly

    Ricardo Guajardo et al.
    Systematic in vivo analysis reveals the divergent engagement of Plexin B structural motifs in distinct neurodevelopmental processes and a regulatory role of convertase cleavage in Plexin B signaling.

    Starvation promotes concerted modulation of appetitive olfactory behavior via parallel neuromodulatory circuits

    Kang I Ko et al.
    Starvation upregulates activity in certain sensory channels and downregulates it in others in what appears to be an optimization strategy that serves to increase the hedonic value of food odors.

    Inhibition of oxidative stress in cholinergic projection neurons fully rescues aging-associated olfactory circuit degeneration in Drosophila

    Ashiq Hussain et al.
    Drosophila genetics and behavior reveal that oxidative stress induced axonal degeneration in a single class of neurons drives the functional decline of an entire neural network and the behavior it controls.

    Massive normalization of olfactory bulb output in mice with a 'monoclonal nose'

    Benjamin Roland et al.
    Inhibitory circuits in the olfactory bulb can amplify or suppress sensory inputs over a wide range of intensities to generate robust mitral cell output.

    The wiring diagram of a glomerular olfactory system

    Matthew E Berck et al.
    The complete neural circuit map of a tractable olfactory system will support studies towards bridging the gap between circuits and behavior.
    1. Neuroscience

    Stepwise wiring of the Drosophila olfactory map requires specific Plexin B levels

    Jiefu Li et al.
    PlexB plays a multifaceted role in instructing the assembly of the Drosophila olfactory circuit through temporally-regulated expression patterns and expression level-dependent effects.
    1. Neuroscience

    Feedback inhibition and its control in an insect olfactory circuit

    Subhasis Ray et al.
    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.
