    Visualization of currents in neural models with similar behavior and different conductance densities

    Leandro M Alonso, Eve Marder
    Visualization methods display the dynamics of the currents in conductance-based model neurons, and show how their contribution changes in response to perturbation.

    Visualization of the type III secretion mediated Salmonella–host cell interface using cryo-electron tomography

    Donghyun Park et al.
    Visualization of the type III secretion mediated Salmonella-host cell interface reveals the intact translocon and the profound remodeling of the host membrane at unprecedented resolution.

    Single-molecule visualization of fast polymerase turnover in the bacterial replisome

    Jacob S Lewis et al.
    The canonical model that the bacterial replisome tightly holds on to its polymerases is challenged by the visualization of rapid holoenzyme exchange, both in vitro and in vivo.

    Dye-enhanced visualization of rat whiskers for behavioral studies

    Jacopo Rigosa et al.
    A simple fluorescent dye method allows visualization of whiskers, facilitating studies of rodent tactile behavior.
    1. Cell Biology

    In vivo vizualisation of mono-ADP-ribosylation by dPARP16 upon amino-acid starvation

    Angelica Aguilera-Gomez et al.
    Amino-acid induced Sec body formation is mediated by PARP16 dependent MARylation of Sec16, a component of the endoplasmic reticulum exit site.

    FRET-based reporters for the direct visualization of abscisic acid concentration changes and distribution in Arabidopsis

    Rainer Waadt et al.
    Fluorescent sensors can track the movement and distribution of the plant hormone abscisic acid in roots and leaves in Arabidopsis.

    Visualization and functional dissection of coaxial paired SpoIIIE channels across the sporulation septum

    Jae Yen Shin et al.
    SpoIIIE forms a protein channel that spans the two lipid bilayers of the septum and mediates chromosome translocation and reversible membrane fission during Bacilus subtilis sporulation.

    Stepwise visualization of membrane pore formation by suilysin, a bacterial cholesterol-dependent cytolysin

    Carl Leung et al.
    Electron and atomic force microscopy show how bacterial toxins bind to a host membrane and assemble into arcs and rings, before undergoing a dramatic, concerted conformational change to insert into the membrane.

    Direct visualization of a native Wnt in vivo reveals that a long-range Wnt gradient forms by extracellular dispersal

    Ariel M Pani, Bob Goldstein
    Free, extracellular dispersal of Wnt proteins generates a long-range gradient during animal development and is required for signaling.
