    Interaction of plasticity and circuit organization during the acquisition of cerebellum-dependent motor learning

    Yan Yang, Stephen G Lisberger
    During learning, one climbing fiber input instructs plasticity that is expressed in the simple-spike responses of cerebellar Purkinje cells, and causes neural learning that may inhibit future climbing fiber instructions.

    Neuronal connectome of a sensory-motor circuit for visual navigation

    Nadine Randel et al.
    Three-dimensional mapping of the neural circuitry that controls movement of a marine worm in response to light provides insights into the evolution of complex visual systems.

    A multilayer circuit architecture for the generation of distinct locomotor behaviors in Drosophila

    Aref Arzan Zarin et al.
    Generation of a premotor/motor neuron comprehensive TEM reconstruction, functional optogenetics, and recurrent network modeling reveals different phase relationships among a subset of Drosophila motor neurons in forward versus backward locomotion.

    Whole-organism behavioral profiling reveals a role for dopamine in state-dependent motor program coupling in C. elegans

    Nathan Cermak et al.
    Simultaneous quantification of each of the main motor programs in the roundworm C. elegans yields new insights into the neural mechanisms that coordinate animal behavior.

    Distributed rhythm generators underlie Caenorhabditis elegans forward locomotion

    Anthony D Fouad et al.
    The forward locomotor circuit of the roundworm Caenorhabditis elegans consists of multiple rhythm-generating units coupled to one another in a bidirectional manner.

    A circuit mechanism for the propagation of waves of muscle contraction in Drosophila

    Akira Fushiki et al.
    Coordinated activation and deactivation of inhibitory neurons triggers sequential muscle contractions that enable fruit fly larvae to propel themselves backwards and forwards.
    1. Neuroscience

    Convergence of monosynaptic and polysynaptic sensory paths onto common motor outputs in a Drosophila feeding connectome

    Anton Miroschnikow et al.
    A parallel neuronal network architecture ensures control of basic feeding reflex circuits via integration of crossmodal sensory information to filter multiple biological events and enhance meaningful behavioral choice.

    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.
