    Phylogenetic variation in cortical layer II immature neuron reservoir of mammals

    Chiara La Rosa et al.
    The higher amount of cortical immature neurons in brains with expanded neocortices may represent a reservoir of young cells for mammals with reduced neurogenesis.

    Neurogenesis: Delayed gratification in the adult brain

    Gerd Kempermann
    Some immature neurons in the cerebral cortex of mammals might wait for years before they become activated and finish their development.

    Polycomb- and REST-associated histone deacetylases are independent pathways toward a mature neuronal phenotype

    James C McGann et al.
    Poised neuronal genes are repressed by REST and Polycomb in embryonic stem cells independently and via different chromatin modifications.

    Structural development and dorsoventral maturation of the medial entorhinal cortex

    Saikat Ray, Michael Brecht
    The medial entorhinal cortex is important for spatial memory formation and matures from dorsal, where smaller spatial-scales are represented, to ventral, where larger spatial-scales are represented.

    Cre-assisted fine-mapping of neural circuits using orthogonal split inteins

    Haojiang Luan et al.
    A genetic method allows neurons to be individually identified and characterized by combining information about both their developmental origins and their mature patterns of gene expression.

    The splicing regulator PTBP2 controls a program of embryonic splicing required for neuronal maturation

    Qin Li et al.
    PTBP2 ensures that adult protein variants are expressed only in mature neurons through regulation of alternative splicing during early neuronal development.

    Distinct roles of NMDA receptors at different stages of granule cell development in the adult brain

    Yangling Mu et al.
    NMDARs promote spine formation to control survival of adult-born granule cells, but gauge spine enlargement and recruitment of AMPARs in both developing and mature neurons.

    Condensin I subunit Cap-G is essential for proper gene expression during the maturation of post-mitotic neurons

    Amira Hassan et al.
    The condensin I subunit Cap-G is expressed in post-mitotic neurons and its removal, especially from less mature neurons, results in gene expression changes, reduced survival and behavioural defects in Drosophila.

    Activity-dependent death of transient Cajal-Retzius neurons is required for functional cortical wiring

    Martina Riva et al.
    The complete elimination of a transient superficial population of neurons, and associated immature circuits, is required for the emergence of functional properties in the mature cerebral cortex.

    Loss of Doc2b does not influence transmission at Purkinje cell to deep nuclei synapses under physiological conditions

    Mehak M Khan, Wade G Regehr
    Eliminating the calcium-binding protein Doc2b does not alter transmission at a mature synapse under physiological conditions, counter to the prevailing view of Doc2b based on cultured neurons.
