    Flexible motor sequence generation during stereotyped escape responses

    Yuan Wang et al.
    Time-ordered and flexible motor sequences in C.elegans are generated by combining an excitatory feedforward coupling and mutual inhibitions between neurons in different functional modules.

    Effective control of SARS-CoV-2 transmission between healthcare workers during a period of diminished community prevalence of COVID-19

    Nick K Jones et al.
    Diminished incidence of COVID-19 amongst healthcare workers in a comprehensive screening programme demonstrates how effective infection control measures and staff testing can prevent hospitals becoming independent 'hubs' of SARS-CoV-2 transmission.

    Screening of healthcare workers for SARS-CoV-2 highlights the role of asymptomatic carriage in COVID-19 transmission

    Lucy Rivett et al.
    3% of >1,000 asymptomatic healthcare workers in their workplace tested positive for SARS-CoV-2, suggesting that comprehensive screening programmes are vital to prevent acquisition of COVID-19 in hospitals.

    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.

    Alterations in the amplitude and burst rate of beta oscillations impair reward-dependent motor learning in anxiety

    Sebastian Sporn et al.
    State anxiety alters the dynamics of beta oscillations during reward-dependent motor learning, thereby impairing proper updating of motor predictions when learning in unstable environments.

    Low-frequency neural activity reflects rule-based chunking during speech listening

    Peiqing Jin et al.
    Neuroimaging reveals that the brain response to spoken language can be better explained by rule-based models than statistical models recently developed in artificial intelligence research.

    The evolutionary history and genomics of European blackcap migration

    Kira Delmore et al.
    Variation in migration can evolve rapidly and traits that comprise this behaviour may be determined by standing variation at a few regulatory regions that are not common across taxonomic groups.

    In vivo assessment of the neural substrate linked with vocal imitation accuracy

    Julie Hamaide et al.
    Song learning accuracy can be predicted and traced in the structural properties of the brains of juvenile male zebra finches already at 20 days post-hatching.

    Structural basis for the activation of PLC-γ isozymes by phosphorylation and cancer-associated mutations

    Nicole Hajicek et al.
    The high-resolution X-ray crystal structure of PLC-γ1 reveals a unifying model for the regulation of the PLC-γ isozymes.

    Correlated evolution between repertoire size and song plasticity predicts that sexual selection on song promotes open-ended learning

    Cristina M Robinson et al.
    A longer birdsong-learning window evolves in response to sexual selection for song complexity and is associated with faster evolution of song performance characteristics.
