    Rate and timing of cortical responses driven by separate sensory channels

    Hannes P Saal et al.
    Signals from different tactile submodalities are integrated optimally to culminate in cortical responses whose rate and timing conveys stimulus information.

    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.

    The trajectory of cortical GABA across the lifespan, an individual participant data meta-analysis of edited MRS studies

    Eric C Porges et al.
    Individual participant data meta-analysis reveals the estimated lifespan trajectory of cortical GABA, characterized by an early rapid increase, followed by a period of stability during early adulthood, and a gradual decrease.

    Auditory cortical alpha/beta desynchronization prioritizes the representation of memory items during a retention period

    Nathan Weisz et al.
    Top-down mediated decreases of beta activity in auditory cortex prior to a predictable distractor in an auditory working memory task is associated with increased representation of to-be-memorized information.

    Distributed functions of prefrontal and parietal cortices during sequential categorical decisions

    Yang Zhou et al.
    Prefrontal cortex plays a leading role in sequential decisions compared to posterior parietal cortex and relies on nonlinear integration of sensory and mnemonic information for decision formation.

    Cortical flow aligns actin filaments to form a furrow

    Anne-Cecile Reymann et al.
    Compressing the actomyosin network by cortical flow causes filaments to align and form a constricting ring.

    A positive-feedback-based mechanism for constriction rate acceleration during cytokinesis in Caenorhabditis elegans

    Renat N Khaliullin et al.
    Positive feedback between contractile ring myosin and compression-driven cortical flow can explain the exponential accumulation of contractile ring components and constriction rate acceleration that ensures timely cell separation during cytokinesis.

    Murine Fam65b forms ring-like structures at the base of stereocilia critical for mechanosensory hair cell function

    Bo Zhao et al.
    Super-resolution microscopy reveals a highly organized compartment in the stereocilia of mechanosensory hair cells of the inner ear, which is critical for hair cell function and affected in disease.

    Stability of neocortical synapses across sleep and wake states during the critical period in rats

    Brian A Cary, Gina G Turrigiano
    Sleep and wake states are not sufficient to drive changes in neocortical synaptic strengths.
