    Cortical flow aligns actin filaments to form a furrow

    Anne-Cecile Reymann et al.
    Compressing the actomyosin network by cortical flow causes filaments to align and form a constricting ring.

    Asymmetric recruitment and actin-dependent cortical flows drive the neuroblast polarity cycle

    Chet Huan Oon, Kenneth E Prehoda
    Neural stem cells dynamically polarize through the stepwise activity of polarized cortical targeting and cortical flows that coalescence discontinuous cortical patches into an organized cap structure.

    More homogeneous capillary flow and oxygenation in deeper cortical layers correlate with increased oxygen extraction

    Baoqiang Li et al.
    Resting-state capillary blood flow and oxygenation are more homogeneous in the deeper cortical layers, underpinning an important mechanism by which the microvascular network adapts to an increased local oxidative metabolism.

    Selectivity to approaching motion in retinal inputs to the dorsal visual pathway

    Todd R Appleby, Michael B Manookin
    Cells in the primate retina show unexpected sensitivity to approaching motion and optical flow.

    Morphogenetic degeneracies in the actomyosin cortex

    Sundar Ram Naganathan et al.
    Distinct molecular functions contribute to the same material property at larger scales leading to degenerate functionality.

    Phenotypic states become increasingly sensitive to perturbations near a bifurcation in a synthetic gene network

    Kevin Axelrod et al.
    Perturbations in the extracellular environment drive transitions from a highly stable memory state to an alternative phenotype in microorganisms.

    Cortex-wide BOLD fMRI activity reflects locally-recorded slow oscillation-associated calcium waves

    Miriam Schwalm et al.
    Locally recorded calcium events related to slow wave activity show a global cortical fMRI BOLD correlate, establishing a direct relation between a basic neurophysiological signal and the macroscopic perspective of pre-clinical fMRI.

    Increasing suppression of saccade-related transients along the human visual hierarchy

    Tal Golan et al.
    Similar to spontaneous eye blinks perceptual stability, despite small saccades, is related to actively silencing transients in the high-level ends of both ventral and dorsal visual cortices, while activity in low-level visual cortex remains unstable.

    Resolving multisensory and attentional influences across cortical depth in sensory cortices

    Remi Gau et al.
    The different laminar profiles observed across the cortical depth for multisensory and attentional influences indicate partly distinct neural circuitries of information-flow control.

    Lamina-specific cortical dynamics in human visual and sensorimotor cortices

    James J Bonaiuto et al.
    Cortical oscillations in human MEG are lamina-specific, with low-frequency activity predominating in deep, and high-frequency activity in more superficial layers of sensory and motor cortices.
