    Flexible motor sequence generation during stereotyped escape responses

    Yuan Wang et al.
    Time-ordered and flexible motor sequences in C.elegans are generated by combining an excitatory feedforward coupling and mutual inhibitions between neurons in different functional modules.

    Neuromodulatory connectivity defines the structure of a behavioral neural network

    Feici Diao et al.
    Using targeted functional manipulations of neural activity to map neuromodulatory connections can deliver considerable insight into the functional architecture of a behaviorally important network even in the absence of information about its synaptic connectivity.

    Cryo-EM structures reveal specialization at the myosin VI-actin interface and a mechanism of force sensitivity

    Pinar S Gurel et al.
    Cryo-EM structures of actomyosin VI in multiple nucleotide states reveal a unique actin-myosin interface and a mechanism of force-sensitivity; furthermore, myosin VI remodels F-actin, suggesting a role for actin structural plasticity during force generation.

    Learning multiple variable-speed sequences in striatum via cortical tutoring

    James M Murray, G Sean Escola
    Inspired by the sparse, sequential neural activity patterns observed in striatum, a new circuit model implements variable-speed activity, the encoding of multiple sequences, and a tutor/student relationship between cortex and striatum.

    Increased longevity due to sexual activity in mole-rats is associated with transcriptional changes in the HPA stress axis

    Arne Sahm et al.
    The fact that sexual activity/reproduction doubles the lifespan of certain rodent species is most likely linked to critical changes in the regulation of the hypothalamic–pituitary–adrenal stress axis.

    Regulation of nerve growth and patterning by cell surface protein disulphide isomerase

    Geoffrey MW Cook et al.
    The nerve growth-repellent activity that generates spinal nerve repeat-patterning in birds and mammals is identified at the molecular level, and a similar system is revealed in adult brain grey matter.

    Fast and flexible sequence induction in spiking neural networks via rapid excitability changes

    Rich Pang, Adrienne L Fairhall
    Biologically plausible changes in the excitabilities of single neurons may suffice to selectively modulate sequential network dynamics, without modifying of recurrent connectivity.

    Restraint of presynaptic protein levels by Wnd/DLK signaling mediates synaptic defects associated with the kinesin-3 motor Unc-104

    Jiaxing Li et al.
    Synaptic defects previously attributed to loss of kinesin function are found to be mediated by the Wnd/DLK axonal injury signaling pathway, which restrains the total levels of presynaptic proteins in response to their accumulation.

    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.

    Output variability across animals and levels in a motor system

    Angela Wenning et al.
    Population output variability in a motor control system varies across levels (CPG, motor neurons, muscles) and can be ascribed to life history differences among animals and in some cases to differences between bilaterally homologous elements.
