    mTOR signaling regulates the morphology and migration of outer radial glia in developing human cortex

    Madeline G Andrews et al.
    mTOR signaling regulates the morphology of a human-enriched neural stem cell population and thus contributes to the radial architecture of the developing human cortex with implications for neurodevelopmental disease.

    Evolution and cell-type specificity of human-specific genes preferentially expressed in progenitors of fetal neocortex

    Marta Florio et al.
    Transcriptomic and genomic analysis provides a resource of 50 primate-specific genes preferentially expressed in neural progenitors of fetal human neocortex, 15 of which are specific to humans.

    Analogous mechanism regulating formation of neocortical basal radial glia and cerebellar Bergmann glia

    Xin Heng et al.
    Genome-wide transcriptional profiling and genetic analyses reveal conserved mechanisms underlying the generation of neocortical basal radial glia and cerebellar Bergmann glia.

    LIS1 determines cleavage plane positioning by regulating actomyosin-mediated cell membrane contractility

    Hyang Mi Moon et al.
    Novel insights into LIS1-dependent regulation of cell membrane contractility and cleavage axis specification identify a key molecular network regulating mitoses of neural progenitors and somatic cells during development.

    Gyrification of the cerebral cortex requires FGF signaling in the mammalian brain

    Naoyuki Matsumoto et al.
    FGF signaling is crucial for gyrus formation, proliferation of outer radial glial cells and expansion of upper layers of the cerebral cortex in gyrencephalic mammals.

    Human-specific ARHGAP11B induces hallmarks of neocortical expansion in developing ferret neocortex

    Nereo Kalebic et al.
    Expression of human-specific gene ARHGAP11B in the developing ferret neocortex leads to an increase in abundance of neural progenitor cells, which results in neocortex expansion.

    Tight junction protein occludin regulates progenitor Self-Renewal and survival in developing cortex

    Raphael M Bendriem et al.
    That early cortical neural progenitor divisions strictly require OCLN isoform expression is a paradigm shift in the functional consideration of this protein best known for promoting between-cell barrier functions.

    Cerebellar folding is initiated by mechanical constraints on a fluid-like layer without a cellular pre-pattern

    Andrew K Lawton et al.
    A multi-phase wrinkling model accounts for the radial and circumferential tension and differential expansion between a uniformly proliferating outer fluid-like layer and an incompressible core that together drive cerebellar folding.
