    Inferring control objectives in a virtual balancing task in humans and monkeys

    Mohsen Sadeghi, Reza Sharif Razavian ... Dagmar Sternad
    A virtual balancing task with parallel experiments on human and non-human primates revealed a spectrum of behaviors (classified by a computational model into position, velocity, or mixed control strategy) that can serve as basis for analyzing neural population dynamics.

    Early life experience sets hard limits on motor learning as evidenced from artificial arm use

    Roni O Maimon-Mor, Hunter R Schone ... Tamar R Makin
    Biological- or artificial-arm experience during early development has a significant effect on artificial-arm motor control in adulthood, providing evidence for limited sensorimotor plasticity beyond childhood.

    Movement-related coupling of human subthalamic nucleus spikes to cortical gamma

    Petra Fischer, Witold J Lipski ... R Mark Richardson
    When coupling between STN spikes and cortical gamma oscillations was strong, subsequent movement was initiated earlier, independent of changes in mean firing rates, demonstrating the importance of relative spike timing.

    Normalisation of brain connectivity through compensatory behaviour, despite congenital hand absence

    Avital Hahamy, Stamatios N Sotiropoulos ... Tamar R Makin
    Building on previous work (Makin et al., 2013), we show that the brains of individuals born without a hand adaptively change to compensate for their disability.

    Postural control of arm and fingers through integration of movement commands

    Scott T Albert, Alkis M Hadjiosif ... Reza Shadmehr
    After a movement, the final posture of the arm is stabilized by a subcortical structure that mathematically integrates movement commands over time.

    De novo learning versus adaptation of continuous control in a manual tracking task

    Christopher S Yang, Noah J Cowan, Adrian M Haith
    Humans can rapidly build a new controller when learning continuous movement tasks and can flexibly integrate this process with adaptation of an existing controller.

    Revealing the neural fingerprints of a missing hand

    Sanne Kikkert, James Kolasinski ... Tamar R Makin
    The brain continues to represent individual fingers in primary somatosensory cortex decades after the amputation of a hand, indicating that cortical maps do not require ongoing sensory input from the body.

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

    Mohsen Omrani, Chantelle D Murnaghan ... Stephen H Scott
    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.
    1. Neuroscience

    Perceptual decisions are biased by the cost to act

    Nobuhiro Hagura, Patrick Haggard, Jörn Diedrichsen
    When choosing between stimuli, the effort required to act on the resulting decision influences the processing of the stimuli themselves.

    Motor cortex signals for each arm are mixed across hemispheres and neurons yet partitioned within the population response

    Katherine Cora Ames, Mark M Churchland
    Neurons in motor cortex contain information about each arm, but these signals are separated into different dimensions, allowing separate control of each arm.
