    A neuromorphic model of active vision shows how spatiotemporal encoding in lobula neurons can aid pattern recognition in bees

    HaDi MaBouDi, Mark Roper ... James AR Marshall
    Active vision dynamically refines spatiotemporal neural representations, optimising visual processing through scanning behaviour and non-associative learning, providing insights into efficient sensory encoding in dynamic environments.

    Active vision of bees in a simple pattern discrimination task

    HaDi MaBouDi, Jasmin Richter ... Lars Chittka
    Bumblebees refine visual discrimination through selective and structured scanning, demonstrating a dynamic interplay between movement and perception in pattern recognition.

    Nanoscale dynamics of synaptic vesicle trafficking and fusion at the presynaptic active zone

    Thirumalini Vaithianathan, Diane Henry ... Gary Matthews
    A combination of tethered diffusion of release-ready synaptic vesicles and vesicle-vesicle fusion supports neurotransmitter release at the presynaptic active zone of sensory synapses.

    The development of active binocular vision under normal and alternate rearing conditions

    Lukas Klimmasch, Johann Schneider ... Jochen Triesch
    A new computational model explains how alternate rearing conditions affect the development of binocular vision.

    Dynamics of gaze control during prey capture in freely moving mice

    Angie M Michaiel, Elliott TT Abe, Cristopher M Niell
    During natural visual behavior in mice, orienting towards a target is driven by head movements, during which the eyes stabilize and shift the visual input.

    A novel region in the CaV2.1 α1 subunit C-terminus regulates fast synaptic vesicle fusion and vesicle docking at the mammalian presynaptic active zone

    Matthias Lübbert, R Oliver Goral ... Samuel M Young Jr
    A novel region in the CaV2.1 α1 subunit regulates coupling of synaptic vesicles to CaV2.1 calcium channels, synaptic vesicle release and docking, and the size of the fast and total releasable pools of synaptic vesicles.

    Munc13 supports fusogenicity of non-docked vesicles at synapses with disrupted active zones

    Chao Tan, Giovanni de Nola ... Pascal S Kaeser
    Hextuple knockout of key active zone proteins strongly reduces the pool of synaptic vesicles available for release, but synapse formation persists.

    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.

    Cell lineage-dependent chiral actomyosin flows drive cellular rearrangements in early Caenorhabditis elegans development

    Lokesh G Pimpale, Teije C Middelkoop ... Stephan W Grill
    Developmentally controlled chiral counter-rotating actomyosin flows drive cell-lineage spindle skews and cell rearrangements during cytokinesis in early nematode development.

    Distinct functional determinants of influenza hemagglutinin-mediated membrane fusion

    Tijana Ivanovic, Stephen C Harrison
    The mechanism of membrane-fusion catalysis in influenza viral infection of target cells is robust against the presence of a large fraction of non-productive viral fusion proteins.
