    Cortical signatures of precision grip force control in children, adolescents, and adults

    Mikkel Malling Beck et al.
    Precise motor control is supported by connectivity within a cortical grasping network from childhood to adulthood, but older individuals display more top-down control and superior motor performance compared to children.

    Kv1.1 channels regulate early postnatal neurogenesis in mouse hippocampus via the TrkB signaling pathway

    Shu-Min Chou et al.
    Kv1.1 potassium channels regulate postnatal neurogenesis in the hippocampus via increasing the membrane excitability that activates the TrkB signaling pathway in a cell-autonomous manner.

    Shape-invariant encoding of dynamic primate facial expressions in human perception

    Nick Taubert et al.
    Contrasting with neural network theories, a study of the cross-species perception of dynamic faces with highly realistic human and monkey avatars reveals independent perceptual encoding of facial shape and expression.

    Propensity for somatic expansion increases over the course of life in Huntington disease

    Radhia Kacher et al.
    Somatic instability of the CAG repeat increases progressively with age and disease progression in Huntington disease mutation carriers, starting with low levels in fetal brain tissues.

    Co-regulation and function of FOXM1/RHNO1 bidirectional genes in cancer

    Carter J Barger et al.
    FOXM1 is co-expressed with its bidirectional gene partner RHNO1, and the two genes promote DNA repair, cell growth and survival, and chemotherapy resistance in ovarian cancer.

    Whole-genome sequencing analysis of semi-supercentenarians

    Paolo Garagnani et al.
    Genetic variants located in DNA repair genes and a reduced burden of somatic mutations protect the oldest living persons from age-related diseases, allowing an healthy aging phenotype.

    Glia actively sculpt sensory neurons by controlled phagocytosis to tune animal behavior

    Stephan Raiders et al.
    A peripheral sense-organ glia actively engulfs fragments of a sensory neuron ending to modify neuron shape and associated animal sensory behavior in Caenorhabditis elegans..

    MicroRNAs mediate precise control of spinal interneuron populations to exert delicate sensory-to-motor outputs

    Shih-Hsin Chang et al.
    The miR-34/449 family is abundantly expressed in the central nervous system, and fine-tunes optimal numbers of spinal interneurons to ensure sensory-motor circuit outputs.

    PMCA-generated prions from the olfactory mucosa of patients with Fatal Familial Insomnia cause prion disease in mice

    Edoardo Bistaffa et al.
    The olfactory mucosa of patients with fatal familial insomnia contains traces of infectious prions, and their analyses could support the clinical diagnosis and elucidate disease-specific mechanisms.
