    Mechanisms that allow cortical preparatory activity without inappropriate movement

    Timothy R Darlington, Stephen G Lisberger
    The use of preparatory activity in the smooth eye movement region of the frontal eye fields as a visual-motor gain signal allows preparation to progress without inappropriate movement.

    Removal of inhibition uncovers latent movement potential during preparation

    Uday K Jagadisan, Neeraj J Gandhi
    Non-invasive disinhibition of the oculomotor system shows that ongoing preparatory activity in the superior colliculus has movement-generating potential and need not rise to threshold in order to produce a saccade.

    Conservation of preparatory neural events in monkey motor cortex regardless of how movement is initiated

    Antonio H Lara et al.
    Voluntary movements are preceded by a temporally flexible preparatory neural process that is present regardless of whether movement is initiated rapidly or thoughtfully.

    Functionally asymmetric motor neurons contribute to coordinating locomotion of Caenorhabditis elegans

    Oleg Tolstenkov et al.
    The 'missing' class of Caenorhabditis elegans excitatory motor neurons, AS, contribute to propagation and coordination of body waves, integrating information from, and feeding back to premotor interneurons byelectrical signaling.

    Evidence for a DNA-relay mechanism in ParABS-mediated chromosome segregation

    Hoong Chuin Lim et al.
    In vitro, in vivo and in silico evidence suggests that bacteria exploit intrinsic chromosomal fluctuations to achieve intracellular transport.

    Nucleolar dynamics and interactions with nucleoplasm in living cells

    Christina M Caragine et al.
    The nucleoplasm surrounding nucleoli in living cells plays a key role in nucleolar dynamics and shape fluctuations in vivo.

    Action history influences subsequent movement via two distinct processes

    Welber Marinovic et al.
    Movement biases due to recent action history involve both dynamically-evolving processes reflecting prediction of future actions, and temporally-stable processes induced by movement repetition.

    A composition-dependent molecular clutch between T cell signaling condensates and actin

    Jonathon A Ditlev et al.
    Compositional changes alter actin binding by phase separated T cell signaling clusters, enabling cluster movement by distinct actin networks.

    Kinetochore-independent chromosome segregation driven by lateral microtubule bundles

    Christina C Muscat et al.
    Chromosomes in C. elegans female reproductive cells segregate through motor-driven movement along lateral microtubule bundles.

    Globus pallidus dynamics reveal covert strategies for behavioral inhibition

    Bon-Mi Gu et al.
    Rats can pre-position the state of their basal ganglia neural networks to adaptively influence their subsequent response to a Go signal.
