    A neural circuit mechanism for regulating vocal variability during song learning in zebra finches

    Jonathan Garst-Orozco et al.
    By demonstrating song learning-related synaptic strengthening and pruning in the vocal control circuits of songbirds, and showing how such changes can reduce the sensitivity of the circuit to ‘noisy’ inputs, a simple neural circuit mechanism for regulating motor variability during motor skill learning is identified.

    Attentional modulation of neuronal variability in circuit models of cortex

    Tatjana Kanashiro et al.
    Attention reduces noise correlations through enhancing inhibitory feedback in cortical networks.

    Hidden synaptic differences in a neural circuit underlie differential behavioral susceptibility to a neural injury

    Akira Sakurai et al.
    Animal-to-animal variability in neural circuit elements is often hidden under normal conditions, but becomes functionally relevant when the system is challenged by injury.

    Thalamocortical synapses in the cat visual system in vivo are weak and unreliable

    Madineh Sedigh-Sarvestani et al.
    A characterization of LGN-V1 synaptic transmission properties demonstrates thalamocortical synapses in vivo are weak and unreliable, but biologically constrained models show they efficiently drive cortex.

    Two central pattern generators from the crab, Cancer borealis, respond robustly and differentially to extreme extracellular pH

    Jessica A Haley et al.
    The rhythms generated by the stomatogastric and cardiac ganglia of the Jonah crab are surprisingly robust but differentially sensitive to acute changes in extracellular pH from pH 5.5 to 10.4.

    miR-9 regulates basal ganglia-dependent developmental vocal learning and adult vocal performance in songbirds

    Zhimin Shi et al.
    Gene manipulation combined with behavior analysis reveals a role of miR-9 in modulating basal-ganglia-dependent developmental vocal learning and adult vocal performance via regulating the FOXP1/FOXP2 gene network and dopamine signaling in songbirds.

    Acetylcholine acts on songbird premotor circuitry to invigorate vocal output

    Paul I Jaffe, Michael S Brainard
    The neuromodulator acetylcholine contributes to state-dependent modulation of motor vigor and variability by direct action on songbird premotor cortex, bypassing basal ganglia circuitry.

    Neural activity in cortico-basal ganglia circuits of juvenile songbirds encodes performance during goal-directed learning

    Jennifer M Achiro et al.
    Activity in cortico-basal ganglia circuits of juvenile songbirds reflects evaluative signals necessary for comparing self-generated behavior to a goal representation during skill learning.

    Neural mechanisms of economic choices in mice

    Masaru Kuwabara et al.
    Inactivation of the lateral orbital area disrupts economic choice behavior and neurons in this area encode the value of offered and chosen options.

    A gene-expression-based neural code for food abundance that modulates lifespan

    Eugeni V Entchev et al.
    TGFβ and serotonin signaling in a neural circuit encodes food availability; these signals regulate the dynamic range and variability on the circuit to impact coding accuracy and lifespan responses.
