    Principles of operation of a cerebellar learning circuit

    David J Herzfeld et al.
    Quantitative analysis of behavior coupled with computational modeling reveal the set of circuit-level principles that underlie cerebellar-dependent motor learning in smooth pursuit eye movements of monkeys across timescales.

    Acetylcholine acts on songbird premotor circuitry to invigorate vocal output

    Paul I Jaffe, Michael S Brainard
    The neuromodulator acetylcholine contributes to state-dependent modulation of motor vigor and variability by direct action on songbird premotor cortex, bypassing basal ganglia circuitry.

    Rules and mechanisms for efficient two-stage learning in neural circuits

    Tiberiu Teşileanu et al.
    Teaching signals from "tutor" brain areas should be adapted to the plasticity mechanisms in "student" areas to achieve efficient learning in two-stage systems such as the vocal control circuit of the songbird.

    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.

    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.

    Remodeling of lumbar motor circuitry remote to a thoracic spinal cord injury promotes locomotor recovery

    Ying Wang et al.
    Retrograde transport of NT-3 stimulated the reorganization of lumbar neural circuitry and synaptic connectivity remote to a thoracic SCI, along with improved behavioral recovery.
    1. Neuroscience

    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

    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.

    Object vision to hand action in macaque parietal, premotor, and motor cortices

    Stefan Schaffelhofer, Hansjörg Scherberger
    The cortical grasping circuit separates but shares visual and motor processes to transform object attributes into appropriate hand movements.
    1. Neuroscience

    Spatiotemporal interplay between multisensory excitation and recruited inhibition in the lamprey optic tectum

    Andreas A Kardamakis et al.
    Signals conveyed from two different senses from a given point in space converge onto the same neurons of the optic tectum that trigger the gaze-control-system, and at the same time inhibit other parts of the tectal motor map.
