    Entorhinal cortex receptive fields are modulated by spatial attention, even without movement

    Niklas Wilming et al.
    Moving covert attention can activate spatial representations in the Entorhinal cortex.

    Intracortical Microstimulation: Regaining the senses of touch and movement

    Victor de Lafuente
    Artificially activating certain neurons in the cortex can make a tetraplegic patient feel naturalistic sensations of skin pressure and arm movement.

    Locomotion: Building behaviors, one layer at a time

    Claire Wyart, Vatsala Thirumalai
    New interneurons are added in the hindbrain to support more complex movements as young zebrafish get older.

    1. Neuroscience

    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.

    Skill learning strengthens cortical representations of motor sequences

    Tobias Wiestler, Jörn Diedrichsen
    Detailed analysis of fMRI data shows that sequences of movements are associated with individual patterns of neural activity that become more distinct with training.

    Ribosomes slide on lysine-encoding homopolymeric A stretches

    Kristin S Koutmou et al.
    Ribosomes undergo an unanticipated movement (‘sliding’) while translating homopolymeric A sequences, which provides a biochemical rationale for the observation that iterated AAA codons are under-represented in gene-coding sequences.

    Uncertainty leads to persistent effects on reach representations in dorsal premotor cortex

    Brian M Dekleva et al.
    When Rhesus monkeys plan reaching movements of which they are not fully confident, a particular area of the brain represents both the chosen action as well as alternate movements, perhaps as an aid for error correction or learning.

    Developmental 'awakening' of primary motor cortex to the sensory consequences of movement

    James C Dooley, Mark S Blumberg
    Early in development, before neurons in primary motor cortex are involved in motor control, they undergo a rapid transition in how they process sensory information following sleep and wake movements.

    A new motor synergy that serves the needs of oculomotor and eye lid systems while keeping the downtime of vision minimal

    Mohammad Farhan Khazali et al.
    Involuntary eye movements that keep images positioned over the center of the retina are synchronized with blinks to minimize disruption to vision.

    Reward prediction error does not explain movement selectivity in DMS-projecting dopamine neurons

    Rachel S Lee et al.
    Despite the fundamental relationship between movement and value, they are represented in a separable manner in dopamine neurons.
