    Polar pattern formation induced by contact following locomotion in a multicellular system

    Masayuki Hayakawa et al.
    Transient cell-cell contact of eukaryotic cells, called contact following locomotion, causes cell density segregation, and its high-density region traveled as a band within the disordered background.

    Apical contacts stemming from incomplete delamination guide progenitor cell allocation through a dragging mechanism

    Eduardo Pulgar et al.
    Incomplete delamination serves as a cellular platform for coordinated tissue movements during development, guiding newly formed progenitor cell groups to the differentiation site.

    Salt-inducible kinase 3 regulates the mammalian circadian clock by destabilizing PER2 protein

    Naoto Hayasaka et al.
    Salt-inducible kinase 3 (SIK3) is an essential component of the mammalian circadian clock machinery, which governs robust circadian behavioral and other rhythms by destabilization of a core clock protein PER2 in a phosphorylation-dependent manner.

    Synchronous activity patterns in the dentate gyrus during immobility

    Martin Pofahl et al.
    Two-photon in vivo calcium imaging reveals short time-scale, synchronous and sparse population activity in dentate gyrus that replays place-related information, and is important for formation of dentate-dependent spatial memory.

    The recovery of standing and locomotion after spinal cord injury does not require task-specific training

    Jonathan Harnie et al.
    Restoring locomotion after complete spinal cord injury does not require locomotor training, only the return of sufficient excitability within neurons of the spinal cord.

    Lognormal firing rate distribution reveals prominent fluctuation–driven regime in spinal motor networks

    Peter C Petersen, Rune W Berg
    Neuronal participation in generation of motor patterns in the spinal circuits is lognormal, which is an indication of a rich diversity of activity within the mean-driven as well as the fluctuation-driven regimes.

    The neuropeptide F/nitric oxide pathway is essential for shaping locomotor plasticity underlying locust phase transition

    Li Hou et al.
    Two neuropeptides, NPF1a and NPF2, act via the nitric oxide signaling pathway in the locust brain to regulate the trait transition between solitary and swarming behavior.

    Emergence of social cluster by collective pairwise encounters in Drosophila

    Lifen Jiang et al.
    Cascades of transient pairwise interactions, stabilized by multisensory inputs, drive the formation of a well-organized social structure from a group of loosely distributed flies.

    Drosophila PSI controls circadian period and the phase of circadian behavior under temperature cycle via tim splicing

    Lauren E Foley et al.
    A screen targeting RNA-associated proteins reveals that PSI regulates timeless alternative splicing and thus controls the period of Drosophila circadian behavior and its phase under temperature cycles.

    Male pheromones modulate synaptic transmission at the C. elegans neuromuscular junction in a sexually dimorphic manner

    Kang-Ying Qian et al.
    Male pheromone environment increases the cholinergic synaptic transmission at the neuromuscular junction in Caenorhabditis elegans hermaphrodites during development, decreasing hermaphrodites' locomotion activity and promoting mating efficiency.
