    Shared behavioral mechanisms underlie C. elegans aggregation and swarming

    Siyu Serena Ding et al.
    Two seemingly distinct behaviors in social C. elegans worms, namely aggregating into groups and swarming over food, are driven by the same underlying mechanisms.

    Complementary encoding of priors in monkey frontoparietal network supports a dual process of decision-making

    Lalitta Suriya-Arunroj, Alexander Gail
    Probability of upcoming actions modulates subclasses of neurons in frontoparietal motor-planning areas in a complementary fashion and frontal-lobe processing takes the leading role when primates commit to a decision.

    Beta band oscillations in motor cortex reflect neural population signals that delay movement onset

    Preeya Khanna, Jose M Carmena
    Using a sequential neurofeedback-arm reaching task, a new link is established among population neural activity patterns, generation of beta oscillations, and motor behavior changes.

    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.

    Human premotor areas parse sequences into their spatial and temporal features

    Katja Kornysheva, Jörn Diedrichsen
    Neuroimaging provides novel insights into how the motor system represents sequences of actions by automatically separating their spatial and temporal features for flexible skill production.

    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.

    Intrinsic control of muscle attachment sites matching

    Alexandre Carayon et al.
    Making a link between deletion of transcription cis-regulatory elements by CrispR/Cas9, obtention of mutants with single muscle morphology defects and their impact on locomotion.

    Neuron hemilineages provide the functional ground plan for the Drosophila ventral nervous system

    Robin M Harris et al.
    Hemilineages link neuronal stem cells to behavioral functions by providing a conserved ground plan of neuronal types that evolution then uses to sculpt different types of walking and flight behaviors.

    Basal ganglia output reflects internally-specified movements

    Mario J Lintz, Gidon Felsen
    The basal ganglia may preferentially influence movements based on internal goals rather than those guided by external stimuli.

    Microsaccadic sampling of moving image information provides Drosophila hyperacute vision

    Mikko Juusola et al.
    New experiments and theory reveal how the ability to see image details depends upon photoreceptor function and eye movements, and how fruit flies (Drosophila) see spatial details beyond the optical limit of their compound eyes.
