    Adult-born neurons facilitate olfactory bulb pattern separation during task engagement

    Wankun L Li et al.
    Adult-born neurons in the olfactory bulb allow state-dependent pattern separation of representations of similar odorants.

    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.

    Nostril-specific and structure-based olfactory learning of chiral discrimination in human adults

    Guo Feng, Wen Zhou
    Training-induced perceptual gain in the discrimination between odor enantiomers is nostril-specific and structure-based, indicating that early olfactory processing of the chemical features of unirhinal input remains plastic in human adults.

    The role of piriform associative connections in odor categorization

    Xiaojun Bao et al.
    Pharmacological fMRI reveals that associative connections contribute to odor categorization by supporting discrimination and generalization at different stages of the human olfactory system.

    Robust olfactory responses in the absence of odorant binding proteins

    Shuke Xiao et al.
    Although odorant binding proteins are widely believed to be required for transport of odorants to receptors, six types of sensilla of Drosophila respond robustly in their absence to many odor stimuli.

    Evolution of neuronal anatomy and circuitry in two highly divergent nematode species

    Ray L Hong et al.
    The substrate for evolutionary divergence does not lie in changes in neuronal cell number or targeting, but rather in sensory perception and synaptic partner choice within invariant, prepatterned neuronal processes.

    A virtual burrow assay for head–fixed mice measures habituation, discrimination, exploration and avoidance without training

    Andrew JP Fink et al.
    A naturalistic assay for head-fixed mice permits observation of a diverse set of innate and learned behaviors without requiring any training.

    Bed nucleus of the stria terminalis regulates fear to unpredictable threat signals

    Travis D Goode et al.
    The bed nucleus of the stria terminalis (BNST) is required for the expression of defensive behavior to uncertain threats, a function that is central to pathological anxiety.

    Synapse-specific opioid modulation of thalamo-cortico-striatal circuits

    William T Birdsong et al.
    By differentially modulating the two major excitatory inputs to the striatum, mu- and delta-opioid receptors regulate the balance between thalamic and cortical inputs to the striatum.
