    From local resynchronization to global pattern recovery in the zebrafish segmentation clock

    Koichiro Uriu et al.
    Theory explains how transport of gene expression vortices by cell advection may cause intermingled defective and normal segments along the body axis during resynchronization experiments in the zebrafish segmentation clock.

    Interplay of cell dynamics and epithelial tension during morphogenesis of the Drosophila pupal wing

    Raphaël Etournay et al.
    Autonomous patterns of cell contraction in the context of localized apical extracellular matrix constraints specify tissue stresses that reshape the wing epithelium.

    Decoupling from yolk sac is required for extraembryonic tissue spreading in the scuttle fly Megaselia abdita

    Francesca Caroti et al.
    Extraembryonic tissue spreading in the scuttle fly Megaselia abdita requires mechanical decoupling from the underlying yolk sac.

    Feedback inhibition and its control in an insect olfactory circuit

    Subhasis Ray et al.
    Electrophysiological recordings and a large-scale biophysical model show that a unique inhibitory neuron plays a central role in structuring olfactory codes in the insect brain.

    Origin and role of the cerebrospinal fluid bidirectional flow in the central canal

    Olivier Thouvenin et al.
    The combination of data and modelling shows the mechanisms underlying bidirectional flow of cerebrospinal fluid and its impact on long range transport in the CSF between brain and spinal cord.

    Spinal V2b neurons reveal a role for ipsilateral inhibition in speed control

    Rebecca A Callahan et al.
    Two anatomically and genetically distinct subtypes of spinal V2b neurons provide inhibition onto motor circuits and serve as a brake on locomotor speed.

    Epithelial cells supply Sonic Hedgehog to the perinatal dentate gyrus via transport by platelets

    Youngshik Choe et al.
    During development the Sonic Hedgehog protein is produced by epithelial structures and acts at a distance in the brain and perhaps in other organs.

    16p11.2 microdeletion imparts transcriptional alterations in human iPSC-derived models of early neural development

    Julien G Roth et al.
    A model of in vitro human corticogenesis identifies alterations in gene expression caused by loss of 16p11.2 CNV genes in hiPSC-derived progenitor cells.
