    Requirement for highly efficient pre-mRNA splicing during Drosophila early embryonic development

    Leonardo Gastón Guilgur et al.
    The need for efficient pre-RNA splicing during early embryonic development of Drosophila indicates that the constraints imposed by the cell cycle are a force capable of driving changes in Eukaryotic gene architecture.

    A stochastic epigenetic switch controls the dynamics of T-cell lineage commitment

    Kenneth KH Ng et al.
    The timing and outcome of mammalian cell lineage decisions can be controlled by slow, stochastic events on individual regulatory gene loci.

    Elastic instability during branchial ectoderm development causes folding of the Chlamydosaurus erectile frill

    Sophie A Montandon et al.
    Robust wrinkling pattern of the frilled dragon’s spectacular erectile ruff emerges from an elastic instability during homogeneous growth of the embryonic neck fold frustrated by its attachment to adjacent tissues.

    Accelerated redevelopment of vocal skills is preceded by lasting reorganization of the song motor circuitry

    Michiel Vellema et al.
    The ability to quickly re-acquire a previously lost motor skill is associated with lasting synaptic changes in the brain circuit that controls that motor skill.

    Constraint and divergence of global gene expression in the mammalian embryo

    Noah Spies et al.
    Embryonic gene expression is strongly influenced by maternal genetic variation and by embryonic variation that acts in cis but not in trans.

    Spatially compartmentalized phase regulation of a Ca2+-cAMP-PKA oscillatory circuit

    Brian Tenner et al.
    Nanodomain clustering of cAMP effectors represents a novel mechanism of cAMP compartmentation within an oscillatory signaling circuit.

    Rules and mechanisms for efficient two-stage learning in neural circuits

    Tiberiu Teşileanu et al.
    Teaching signals from "tutor" brain areas should be adapted to the plasticity mechanisms in "student" areas to achieve efficient learning in two-stage systems such as the vocal control circuit of the songbird.

    Achieving functional neuronal dendrite structure through sequential stochastic growth and retraction

    André Ferreira Castro et al.
    An optimal wire and function trade-off emerges from noisy growth and stochastic retraction during Drosophila class I ventral posterior dendritic arborisation (c1vpda) dendrite development.

    T2N as a new tool for robust electrophysiological modeling demonstrated for mature and adult-born dentate granule cells

    Marcel Beining et al.
    T2N, a novel interface between Matlab, TREES toolbox and NEURON, was used to generate compartmental models that reproduce the electrophysiology of dentate granule cells over a multitude of species, experimental conditions and developmental stages.
