    Distributed task-specific processing of somatosensory feedback for voluntary motor control

    Mohsen Omrani et al.
    Somatosensory feedback is transmitted to many sensory and motor cortical regions within 25 milliseconds and ongoing behavioural tasks alter the spatiotemporal pattern of this perturbation-related activity, supporting rapid motor responses to attain behavioural goals.

    A synergy-based hand control is encoded in human motor cortical areas

    Andrea Leo et al.
    The human brain encodes coordinated patterns of joint movements – synergies – to increase the efficiency with which it can control complex hand movements.

    Down regulation of vestibular balance stabilizing mechanisms to enable transition between motor states

    Romain Tisserand et al.
    Down regulation of the gain from the vestibular sensory sources prior to the initiation of movement is a motor control solution to overcome the reflex-stabilizing mechanisms to enable motion from a postural orientation.

    A neural circuit mechanism for regulating vocal variability during song learning in zebra finches

    Jonathan Garst-Orozco et al.
    By demonstrating song learning-related synaptic strengthening and pruning in the vocal control circuits of songbirds, and showing how such changes can reduce the sensitivity of the circuit to ‘noisy’ inputs, a simple neural circuit mechanism for regulating motor variability during motor skill learning is identified.

    Analysis of the NK2 homeobox gene ceh-24 reveals sublateral motor neuron control of left-right turning during sleep

    Juliane Schwarz, Henrik Bringmann
    A genetic analysis has identified the cholinergic SIA sublateral motor neurons, which innervate all four body wall muscles separately, as crucial regulators of turning around during sleep in Caenorhabditis elegans.

    Motor control of Drosophila feeding behavior

    Olivia Schwarz et al.
    The neuroanatomical and functional analysis of genetically-identified motoneurons controlling all major steps of Drosophila proboscis extension provides new insights into the architecture of a motor circuitry controlling a reaching-like behavior.

    The C-terminal region of the motor protein MCAK controls its structure and activity through a conformational switch

    Sandeep K Talapatra et al.
    Structural analysis of the kinesin-13 MCAK bound to its C-terminal tail reveals the molecular basis for the conformation of kinesin-13 in solution and the mechanism that triggers long-range conformational changes upon microtubule binding.

    Frizzled3 controls axonal development in distinct populations of cranial and spinal motor neurons

    Zhong L Hua et al.
    The signaling molecule Frizzled3 plays a part in the development of the nervous system by controlling the ability of motor neurons to form connections with distant target muscles.

    Nociceptive interneurons control modular motor pathways to promote escape behavior in Drosophila

    Anita Burgos et al.
    A class of interneuron is identified that promotes escape behavior downstream of nociceptor inputs via connections to nociceptive integrator and premotor networks.

    Body side-specific control of motor activity during turning in a walking animal

    Matthias Gruhn et al.
    Turning in an insect is the combined result of body-side-specific modifications in processing of local sensory feedback, and modification of local central pattern generator activity.
