    A circuit mechanism for the propagation of waves of muscle contraction in Drosophila

    Akira Fushiki, Maarten F Zwart ... Akinao Nose
    Coordinated activation and deactivation of inhibitory neurons triggers sequential muscle contractions that enable fruit fly larvae to propel themselves backwards and forwards.

    Foveal vision anticipates defining features of eye movement targets

    Lisa M Kroell, Martin Rolfs
    Before a saccadic eye movement to a location in the visual periphery, human observers' foveal vision becomes more sensitive to the features defining the eye movement target, anticipating information that will soon be fixated in a retinotopic reference frame.

    Ataxin-1 oligomers induce local spread of pathology and decreasing them by passive immunization slows Spinocerebellar ataxia type 1 phenotypes

    Cristian A Lasagna-Reeves, Maxime WC Rousseaux ... Huda Y Zoghbi
    Building on previous work (Lasagna-Reeves et al., 2015) it is shown that polyglutamine ATXN1 oligomers propagate locally in SCA1 mice, and that passive immunotherapy targeting soluble oligomers can lead to an improvement in motor coordination and a modest increase in life span.

    Removal of inhibition uncovers latent movement potential during preparation

    Uday K Jagadisan, Neeraj J Gandhi
    Non-invasive disinhibition of the oculomotor system shows that ongoing preparatory activity in the superior colliculus has movement-generating potential and need not rise to threshold in order to produce a saccade.

    A modular platform for automated cryo-FIB workflows

    Sven Klumpe, Herman KH Fung ... Julia Mahamid
    SerialFIB is an adaptable open-source software designed for streamlining, advanced development and automation of cryo-focused ion beam-based cellular preparations for in situ cryo-electron tomography.

    Interplay between external inputs and recurrent dynamics during movement preparation and execution in a network model of motor cortex

    Ludovica Bachschmid-Romano, Nicholas G Hatsopoulos, Nicolas Brunel
    A recurrent neural network model with parameters constrained by data explains mechanisms for how tuning properties of motor cortical neurons change during movement preparation and execution in a monkey performing a reaching task, and accurately reproduces neural dynamics from recordings.

    Motor Networks: When preparation pays off

    Mark M Churchland
    Computational principles shed light on why movement is preceded by preparatory activity within the neural networks that control muscles.

    EHMT2 methyltransferase governs cell identity in the lung and is required for KRAS G12D tumor development and propagation

    Ariel Pribluda, Anneleen Daemen ... Melissa R Junttila
    G9a regulates chromatin-bound b-catenin enabling cell-intrinsic control of WNT signaling-mediated cell fate decisions.

    Emergence and propagation of epistasis in metabolic networks

    Sergey Kryazhimskiy
    Mutations that affect a metabolic network generically exhibit epistasis, which propagates to higher level phenotypes, such as fitness, carrying some information about the network’s topology.

    Periodic propagating waves coordinate RhoGTPase network dynamics at the leading and trailing edges during cell migration

    Alfonso Bolado-Carrancio, Oleksii S Rukhlenko ... Boris N Kholodenko
    Different RhoA and Rac1 dynamics at the cell front and rear are coordinated through periodic GTPase waves, which define the minimal autonomous biochemical machinery necessary and sufficient for cell migration.
