    Shugoshin biases chromosomes for biorientation through condensin recruitment to the pericentromere

    Kitty F Verzijlbergen, Olga O Nerusheva ... Adele L Marston
    Shugoshin proteins help to align chromosomes so that copies of the same chromosome attach to microtubules from opposite poles during cell division.

    Encoding and control of orientation to airflow by a set of Drosophila fan-shaped body neurons

    Timothy A Currier, Andrew MM Matheson, Katherine I Nagel
    Electrophysiology identifies a population of fan-shaped body neurons that encode airflow in two directions relative to the fly midline and whose silencing disrupts proper orientation to airflow.

    Processing of motion boundary orientation in macaque V2

    Heng Ma, Pengcheng Li ... Haidong D Lu
    Area V2 in macaque monkeys contributes to the perception of the outlines of moving objects and achieves this through a local computation.

    Precise and stable edge orientation signaling by human first-order tactile neurons

    Vaishnavi Sukumar, Roland S Johansson, J Andrew Pruszynski
    Individual human first-order tactile neurons, those that innervate the mechanoreceptors in the skin, can signal information about edge orientation differences at the limit of what people can feel and across a broad range of speeds relevant for real-world hand use.

    Geometric control of myosin II orientation during axis elongation

    Matthew F Lefebvre, Nikolas H Claussen ... Sebastian J Streichan
    During Drosophila axis elongation, the orientational pattern of the cytoskeleton is in good approximation stationary, while the genes thought to instruct these patterns are transported with the tissue flow.

    Coding strategies in the otolith system differ for translational head motion vs. static orientation relative to gravity

    Mohsen Jamali, Jerome Carriot ... Kathleen E Cullen
    Through different coding strategies, irregular and regular otolith afferents preferentially encode translational self-motion and changes in static head orientation relative to gravity.

    Specific polar subpopulations of astral microtubules control spindle orientation and symmetric neural stem cell division

    Felipe Mora-Bermúdez, Fumio Matsuzaki, Wieland B Huttner
    Mammalian neural stem cells specifically regulate a subset of astral microtubules to govern the subtle changes in spindle orientation that underlie symmetric vs asymmetric cell division during embryonic cortical neurogenesis.

    Stimulus vignetting and orientation selectivity in human visual cortex

    Zvi N Roth, David J Heeger, Elisha P Merriam
    Functional MRI measurements of orientation reflect coarse-scale biases that are wholly determined by second-order interactions between the stimulus aperture and the underlying orientation.

    Telophase correction refines division orientation in stratified epithelia

    Kendall J Lough, Kevin M Byrd ... Scott E Williams
    Telophase reorientation corrects errors in spindle orientation that persist after imprecise initial spindle positioning during early mitosis, and contributes to balancing self-renewal with differentiation during epidermal development.

    Fast and accurate edge orientation processing during object manipulation

    J Andrew Pruszynski, J Randall Flanagan, Roland S Johansson
    Tactile edge orientation processing during object manipulation is many times better than previously thought based on perceptual studies.
