    Local processing in neurites of VGluT3-expressing amacrine cells differentially organizes visual information

    Jen-Chun Hsiang et al.
    Neurite arbors of VGluT3-expressing amacrine cells (VG3-ACs) process visual information locally uniformly detecting object motion while varying in contrast preferences; and in spite of extensive overlap between arbors of neighboring cells population activity in the VG3-AC plexus encodes stimulus positions with subcellular precision.

    An excitatory amacrine cell detects object motion and provides feature-selective input to ganglion cells in the mouse retina

    Tahnbee Kim et al.
    The mouse visual system is able to detect small moving objects due to the activity of VG3-amacrine cells, an unusual type of modulatory cell that uses the transmitter glutamate to activate retinal output cells.

    Cell lineage and cell cycling analyses of the 4d micromere using live imaging in the marine annelid Platynereis dumerilii

    B Duygu Özpolat et al.
    Lineage tracing at single-cell resolution reveals the presence of mesoteloblasts, the embryonic origin of mesodermal growth zone cells, and diverse cell cycling patterns of these lineages in the 'Polychaete' annelid Platynereis.

    1. Neuroscience

    Stimulus-dependent recruitment of lateral inhibition underlies retinal direction selectivity

    Qiang Chen et al.
    Synapse-specific genetic manipulations show that distinct GABAergic inputs are differentially recruited to encode motion direction in the retina in a stimulus-dependent manner.

    Quantitative 3D-imaging for cell biology and ecology of environmental microbial eukaryotes

    Sebastien Colin et al.
    Three-dimensional fluorescence imaging of microbial eukaryotes in environmental samples allows accurate automated taxonomic profiling and quantitative data about ultrastructures and interactions of organisms.

    Protocadherin-dependent dendritic self-avoidance regulates neural connectivity and circuit function

    Dimitar Kostadinov, Joshua R Sanes
    Patterning of dendrites by protocadherin-dependent self-avoidance and self/non-self discrimination is required for proper function of a retinal circuit that computes the direction of motion.

    An extracellular biochemical screen reveals that FLRTs and Unc5s mediate neuronal subtype recognition in the retina

    Jasper J Visser et al.
    An integrated approach for studying laminar organization in the developing mouse retina identifies two families of extracellular recognition proteins that mediate neuronal subtype-specific recognition.

    The LIM protein complex establishes a retinal circuitry of visual adaptation by regulating Pax6 α-enhancer activity

    Yeha Kim et al.
    Regulation of Pax6 expression through the α-enhancer fine-tunes amacrine cell subtype number, and consequently, the visual output of the retina.

    Ecology and evolution of viruses infecting uncultivated SUP05 bacteria as revealed by single-cell- and meta-genomics

    Simon Roux et al.
    Single-cell amplified genome sequencing uncovers virus-host interactions in uncultivated sulfur-oxidizing bacteria with relevance to coupled biogeochemical cycling in marine oxygen minimum zones.
