    NF-κB oscillations translate into functionally related patterns of gene expression

    Samuel Zambrano, Ilario De Toma ... Alessandra Agresti
    NF-κB oscillations synchronize to external perturbations as a damped oscillator, producing different transcription dynamics.

    Peripheral sensory coding through oscillatory synchrony in weakly electric fish

    Christa A Baker, Kevin R Huck, Bruce A Carlson
    Sensory receptors encode stimuli by transiently synchronizing ongoing electrical oscillations, conferring enhanced sensitivity to communication signals produced by large groups of conspecifics.

    Firing rate-dependent phase responses of Purkinje cells support transient oscillations

    Yunliang Zang, Sungho Hong, Erik De Schutter
    Computational and theoretical models show that rate adaptation of phase responses can regulate Purkinje cell outputs by forming transient oscillations in fast-spiking neurons.

    Wings and halteres act as coupled dual oscillators in flies

    Tanvi Deora, Siddharth S Sane, Sanjay P Sane
    Flight system of flies is driven by wings and mechanosensory halteres that operate as independently driven but coupled oscillators, thereby imparting robustness against wing or thorax damage.

    Robust, coherent, and synchronized circadian clock-controlled oscillations along Anabaena filaments

    Rinat Arbel-Goren, Valentina Buonfiglio ... Joel Stavans
    Noisy circadian clocks in Anabaena, coupled by cell-cell communication, display high spatio-temporal coherence and can be robustly described by incorporating demographic noise in a theoretical model of coupled clock arrays.

    Multiple mechanisms link prestimulus neural oscillations to sensory responses

    Luca Iemi, Niko A Busch ... Vadim V Nikulin
    Neural oscillations prior to a stimulus modulate the strength of early and late responses in opposite directions via distinct mechanisms.

    Rapid cell-free forward engineering of novel genetic ring oscillators

    Henrike Niederholtmeyer, Zachary Z Sun ... Sebastian J Maerkl
    Rapid forward engineering can be accomplished using cell-free systems, as demonstrated by the implementation and characterization of novel genetic oscillators in a cell-free system and their consequent transfer to cells.

    Persistence, period and precision of autonomous cellular oscillators from the zebrafish segmentation clock

    Alexis B Webb, Iván M Lengyel ... Andrew C Oates
    Time-lapse recording and theoretical analysis of individual cells isolated from the zebrafish segmentation clock reveal that they behave as self-sustained, autonomous oscillators with distinctive noisy dynamics.

    Disrupting abnormal neuronal oscillations with adaptive delayed feedback control

    Domingos Leite de Castro, Miguel Aroso ... Paulo Aguiar
    Adaptive delayed feedback control is presented as a new real-time, closed-loop control algorithm for neurostimulation which can disrupt oscillations and reduce network synchrony in neuronal populations.

    Phase response analyses support a relaxation oscillator model of locomotor rhythm generation in Caenorhabditis elegans

    Hongfei Ji, Anthony D Fouad ... Christopher Fang-Yen
    Behavioral, optogenetic, and computational modeling analyses show that the roundworm Caenorhabditis elegans uses a relaxation oscillation mechanism to generate rhythmic locomotor patterns.
