    Point of View: Towards a mechanistic foundation of evolutionary theory

    Michael Doebeli et al.
    A description of evolution that is based on birth-death processes, and in which fitness is at most a derived quantity, is advocated.

    Presynaptic morphology and vesicular composition determine vesicle dynamics in mouse central synapses

    Laurent Guillaud et al.
    In central synapses, the mobility and supply of synaptic vesicles are determined by two independent biological factors: the morphological and structural organization of nerve terminals and the molecular signature of vesicles.

    The step-wise pathway of septin hetero-octamer assembly in budding yeast

    Andrew Weems, Michael McMurray
    In budding yeast cells, slow monomeric septin GTPase activity and the cytosolic GTP:GDP ratio dictate the relative incorporation of alternative subunits during septin hetero-oligomer assembly, which proceeds by discrete, ordered steps dependent on allostery between interaction interfaces.

    Test of the 'glymphatic' hypothesis demonstrates diffusive and aquaporin-4-independent solute transport in rodent brain parenchyma

    Alex J Smith et al.
    Solute movement in brain extracellular space is determined by solute diffusion, and does not depend on convection or aquaporin-4 expression as predicted by the glymphatic mechanism.

    Locus coeruleus to basolateral amygdala noradrenergic projections promote anxiety-like behavior

    Jordan G McCall et al.
    Selective activation of locus coeruleus noradrenergic terminals drives anxiety-like behaviors through activation of β-adrenergic receptors in the basolateral amygdala.

    Pioneer neurog1 expressing cells ingress into the otic epithelium and instruct neuronal specification

    Esteban Hoijman et al.
    Quantitative 4D image analysis identifies a group of cells which enter into the otic primordium during morphogenesis and instructs neuronal specification.

    Genetic specification of left–right asymmetry in the diaphragm muscles and their motor innervation

    Camille Charoy et al.
    Analysis of embryonic mouse diaphragm reveals muscle and nerve left–right asymmetries set by a Nodal-dependent genetic cascade, which imprints different molecular signatures to left and right motoneurons that shape their innervation pattern.

    Lognormal firing rate distribution reveals prominent fluctuation–driven regime in spinal motor networks

    Peter C Petersen, Rune W Berg
    Neuronal participation in generation of motor patterns in the spinal circuits is lognormal, which is an indication of a rich diversity of activity within the mean-driven as well as the fluctuation-driven regimes.
