    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.

    MicroRNAs mediate precise control of spinal interneuron populations to exert delicate sensory-to-motor outputs

    Shih-Hsin Chang et al.
    The miR-34/449 family is abundantly expressed in the central nervous system, and fine-tunes optimal numbers of spinal interneurons to ensure sensory-motor circuit outputs.

    Phrenic-specific transcriptional programs shape respiratory motor output

    Alicia N Vagnozzi et al.
    Molecular programs regulated by Hox5 transcription factors establish a set of inhibitory inputs onto phrenic motor neurons that control the pattern of respiratory motor output.

    Synaptic up-scaling preserves motor circuit output after chronic, natural inactivity

    Joseph M Santin et al.
    Synaptic scaling maintains motor output from the respiratory network of bullfrogs after months of inactivity in the winter, providing evidence for homeostatic plasticity in response to large ecologically relevant perturbations in neuronal activity.

    Motor context dominates output from purkinje cell functional regions during reflexive visuomotor behaviours

    Laura D Knogler et al.
    Purkinje cells of the cerebellum, a conserved vertebrate brain region important for sensorimotor integration, receive sensory and motor information from distinct input streams and are functionally clustered into modules reflecting the larval zebrafish's behavioral repertoire.
    1. Neuroscience

    An open cortico-basal ganglia loop allows limbic control over motor output via the nigrothalamic pathway

    Sho Aoki et al.
    A novel connection from ventral striatum to motor cortex enables emotion and motivation to influence action and motor control.

    Modular output circuits of the fastigial nucleus for diverse motor and nonmotor functions of the cerebellar vermis

    Hirofumi Fujita et al.
    Medial cerebellar nucleus comprises five major types of excitatory projection neurons differentially connected with specific subsets of inferior olive neurons, Purkinje cells, and somatomotor, oromotor, positional-autonomic, orienting and arousal circuits.

    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.

    Target-specific membrane potential dynamics of neocortical projection neurons during goal-directed behavior

    Takayuki Yamashita, Carl CH Petersen
    A learning-induced, motor-related, projection-specific signal from S1 to S2 accompanies reward-based-learning of a goal-directed sensorimotor transformation of whisker sensation into licking motor output.
    1. Neuroscience

    Opioids modulate an emergent rhythmogenic process to depress breathing

    Xiaolu Sun et al.
    Inspiratory rhythmogenesis is mediated by an emergent mechanism independent of bursts associated with motor output and is modulated by opioids, pointing to strategies for ameliorating opioid-induced respiratory depression.
