    Social structure learning in human anterior insula

    Tatiana Lau et al.
    A domain-general structure learning mechanism, supported by anterior insula, moves beyond explicit category labels and dyadic similarity as the sole inputs to social group representations and predicts ally-choice behavior.

    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.

    FoxP2 isoforms delineate spatiotemporal transcriptional networks for vocal learning in the zebra finch

    Zachary Daniel Burkett et al.
    Basal ganglia gene coexpression patterns shift across the sensorimotor critical period for vocal learning.

    Neural arbitration between social and individual learning systems

    Andreea Oliviana Diaconescu et al.
    Arbitration is formalised as the relative precision of predictions afforded by reward and social learning systems and is represented in modality-specific dopaminergic and dopaminoceptive regions, including the midbrain and amygdala.

    Social aversive generalization learning sharpens the tuning of visuocortical neurons to facial identity cues

    Yannik Stegmann et al.
    Measures of visuocortical activity during aversive generalization learning revealed sharpened representations of facial identity, reflecting inhibitory interactions between neuronal populations that represent facial features associated with threat versus safety.

    Neural mechanisms of social learning in the female mouse

    Yuan Gao et al.
    After mating, female mice form a sensory memory of the stud male's pheromones that correlates with striking changes in responsiveness of the specific neural ensemble activated by her partner.

    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.

    A role for descending auditory cortical projections in songbird vocal learning

    Yael Mandelblat-Cerf et al.
    Midbrain dopaminergic neurons and a cortex-like structure called the arcopallium form part of a circuit that enables young songbirds to compare their own song with a template stored in memory, and use any discrepancies to improve their performance.

    A subcortical circuit linking the cerebellum to the basal ganglia engaged in vocal learning

    Ludivine Pidoux et al.
    The cerebellum sends a functional input to the song-related basal ganglia via the thalamus in songbirds that can modify premotor activity, and it participates to song learning in juvenile birds.

    The ubiquitin-proteasome system regulates focal adhesions at the leading edge of migrating cells

    Anjali Teckchandani, Jonathan A Cooper
    A ubiquitin E3 ligase localizes to focal adhesions at the front of migrating human cells where it regulates cytoskeletal dynamics by targeting a focal adhesion protein.
