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

    Benjamin Roland, Rebecca Jordan ... Alexander Fleischmann
    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 activity-dependent histone variant H2BE modulates the life span of olfactory neurons

    Stephen W Santoro, Catherine Dulac
    A genome-organizing protein that is present only in the olfactory system of mice has been found to orchestrate changes in the relative numbers of different odor-sensing neurons on the basis of how active these neurons are.

    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.
    1. Neuroscience

    Parallel encoding of sensory history and behavioral preference during Caenorhabditis elegans olfactory learning

    Christine E Cho, Chantal Brueggemann ... Cornelia I Bargmann
    Odor conditioning induces two changes in olfactory neurons: non-associative sensory adaptation to odor history, and associative, bidirectional changes in behavioral output that are oppositely regulated in aversive and appetitive learning.

    Circuit mechanisms encoding odors and driving aging-associated behavioral declines in Caenorhabditis elegans

    Sarah G Leinwand, Claire J Yang ... Sreekanth H Chalasani
    Neurotransmission pathways from primary to secondary neurons encode odor and underlie age-related sensory behavioral declines.

    Single-cell transcriptomes of developing and adult olfactory receptor neurons in Drosophila

    Colleen N McLaughlin, Maria Brbić ... Hongjie Li
    Single-cell transcriptomes of olfactory receptor neurons at multiple developmental stages reveal cell-type-specific gene expression programs that underlie their development and sensory biology.

    Variation in olfactory neuron repertoires is genetically controlled and environmentally modulated

    Ximena Ibarra-Soria, Thiago S Nakahara ... Darren W Logan
    The neuronal composition of a mouse’s nose is individually unique due to a combination of olfactory experience and genetic variation local to olfactory receptor genes.
    1. Developmental Biology

    Opposing, spatially-determined epigenetic forces impose restrictions on stochastic olfactory receptor choice

    Elizaveta V Bashkirova, Nell Klimpert ... Stavros Lomvardas
    Dorsoventral gradients of transcription factors NFIA, B, and X impose epigenetic and transcriptional spatial restrictions to olfactory receptor expression.

    Adaptation of olfactory receptor abundances for efficient coding

    Tiberiu Teşileanu, Simona Cocco ... Vijay Balasubramanian
    A model of efficient coding by olfactory neurons explains context-dependence observed in the effect of perturbations to the olfactory environment.
    1. Neuroscience

    Acquisition of innate odor preference depends on spontaneous and experiential activities during critical period

    Qiang Qiu, Yunming Wu ... C Ron Yu
    A delicate balance of neural activity is required during critical period in establishing innate odor preference.
