    Tuning of feedforward control enables stable muscle force-length dynamics after loss of autogenic proprioceptive feedback

    Joanne C Gordon et al.
    Running guinea fowl maintain stable running after loss of the stretch reflex in a major ankle extensor muscle, by increasing feedforward muscle activation to maintain ankle stiffness and work output.

    Vestigial auriculomotor activity indicates the direction of auditory attention in humans

    Daniel J Strauss et al.
    Recordings of ear muscles in humans show that ears attempt to pivot in the direction that requires attention.

    Ant collective cognition allows for efficient navigation through disordered environments

    Aviram Gelblum et al.
    When real ants confront the classical 'Ant-in-a-labyrinth' physics problem where a random walker traverses a percolated environment, they employ active extended sensing and collective cognition to outperform passive physical solutions.

    Automated task training and longitudinal monitoring of mouse mesoscale cortical circuits using home cages

    Timothy H Murphy et al.
    A new methodology and protocol use automated brain imaging and task training technology to probe links between behavior and mouse cortical circuits.

    The dynamic transmission of positional information in stau- mutants during Drosophila embryogenesis

    Zhe Yang et al.
    In stau-mutants, the Hunchback boundary shifts posteriorly by 10% EL but shows comparable variability to that of the wild type in short time windows in nuclear cycle 14.

    Alcids ‘fly’ at efficient Strouhal numbers in both air and water but vary stroke velocity and angle

    Anthony B Lapsansky et al.
    Four species of seabird produce efficient propulsive wakes while flying in the air and while swimming underwater suggesting that selection has optimized these species for locomotion in remarkably different fluids.

    Global sleep homeostasis reflects temporally and spatially integrated local cortical neuronal activity

    Christopher W Thomas et al.
    The global sleep homeostatic process tracks sleep-wake history by integrating local cortical neuronal activity over time and space, rather than directly reflecting changes in specific homeostatically regulated physiological variables.

    Fast and reversible neural inactivation in macaque cortex by optogenetic stimulation of GABAergic neurons

    Abhishek De et al.
    Optogenetic activation of cortical GABAergic cells in macaques yields robust and reversible behavioral deficits.

    Brain states govern the spatio-temporal dynamics of resting-state functional connectivity

    Felipe Aedo-Jury et al.
    Distinct brain states govern resting state functional architecture revealed by neurophysiologically defined simultaneous optic-fiber-based calcium recordings and task-free functional magnetic resonance imaging (fMRI) in rats.

    Paranoia as a deficit in non-social belief updating

    Erin J Reed et al.
    Paranoia is underwritten by variation in prior beliefs about how the world will change and how to learn from those changes.
