    Nuclei determine the spatial origin of mitotic waves

    Felix E Nolet et al.
    Nuclei and spatial system dimensions control local concentrations of cell cycle regulators, determining the spatial origin of waves that coordinate​ DNA replication and, subsequently, cell division.

    DMT alters cortical travelling waves

    Andrea Alamia et al.
    Psychedelics induce a pattern of cortical activity very similar to the one observed during visual perception, despite participants had shut eyes.

    Detecting changes in dynamic and complex acoustic environments

    Yves Boubenec et al.
    Psychophysics experiments and EEG recordings reveal that people's performance in detecting unexpected changes in complex auditory scenes can be modeled as a process of sensory evidence accumulation.

    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.

    Zygotic gene activation in the chicken occurs in two waves, the first involving only maternally derived genes

    Young Sun Hwang et al.
    In Aves, the first wave of transcription is derived exclusively from the maternal genome.

    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.

    Periodic propagating waves coordinate RhoGTPase network dynamics at the leading and trailing edges during cell migration

    Alfonso Bolado-Carrancio et al.
    Different RhoA and Rac1 dynamics at the cell front and rear are coordinated through periodic GTPase waves, which define the minimal autonomous biochemical machinery necessary and sufficient for cell migration.

    Waves of actin and microtubule polymerization drive microtubule-based transport and neurite growth before single axon formation

    Amy M Winans et al.
    Waves of polymerizing actin work in concert with microtubule polymerization to lay down more microtubules tracks and transiently increase microtubule-based transport into the growing neurite.

    Aven recognition of RNA G-quadruplexes regulates translation of the mixed lineage leukemia protooncogenes

    Palaniraja Thandapani et al.
    Arginine methylation regulates mRNA translation of key protooncogenes via an RGG/RG motif-containing protein called Aven.

    Adapting non-invasive human recordings along multiple task-axes shows unfolding of spontaneous and over-trained choice

    Yu Takagi et al.
    Adaptation along multiple task-axes reveals choice traces at millisecond resolution in non-invasive recordings from human premotor cortex and provides evidence that theories of top-down control hold even after extensive experience.
