    16p11.2 microdeletion imparts transcriptional alterations in human iPSC-derived models of early neural development

    Julien G Roth et al.
    A model of in vitro human corticogenesis identifies alterations in gene expression caused by loss of 16p11.2 CNV genes in hiPSC-derived progenitor cells.

    Dynamics of nevus development implicate cell cooperation in the growth arrest of transformed melanocytes

    Rolando Ruiz-Vega et al.
    Spontaneous growth arrest of transformed melanocytes (resulting in benign “moles”) does not result from cell-autonomous oncogene-induced senescence, but can be explained by collective mechanisms used in normal tissue size control.

    Synchronous activity patterns in the dentate gyrus during immobility

    Martin Pofahl et al.
    Two-photon in vivo calcium imaging reveals short time-scale, synchronous and sparse population activity in dentate gyrus that replays place-related information, and is important for formation of dentate-dependent spatial memory.

    Properties of multivesicular release from mouse rod photoreceptors support transmission of single-photon responses

    Cassandra L Hays et al.
    To improve the reliability of transmitting small single-photon voltage responses, rod photoreceptor cells release synaptic vesicles in regularly timed multivesicular events that are exquisitely sensitive to small voltage changes.

    Cortical astrocytes independently regulate sleep depth and duration via separate GPCR pathways

    Trisha V Vaidyanathan et al.
    Cortical astrocytes play key roles in NREM sleep by regulating sleep depth and duration through separate GPCR pathways, and differentially control neuronal slow-wave activity in local and remote cortical circuits.

    Antagonistic roles for Ataxin-2 structured and disordered domains in RNP condensation

    Amanjot Singh et al.
    Ataxin-2 interacts with neuronal mRNA in RNP granules.

    C. elegans orthologs MUT-7/CeWRN-1 of Werner syndrome protein regulate neuronal plasticity

    Tsung-Yuan Hsu et al.
    The olfactory learning of Caenorhabditis elegans shows that the exonuclease and helicase domains of human Werner syndrome protein (WRN) coordinately regulate the biogenesis of small interfering RNAs to promote neuronal plasticity.

    Female-biased upregulation of insulin pathway activity mediates the sex difference in Drosophila body size plasticity

    Jason W Millington et al.
    The ability to adjust body size in response to diet is greater in Drosophila females than males because of a sex difference in the nutrient-dependent regulation of the insulin pathway.

    Efficient coding of natural scene statistics predicts discrimination thresholds for grayscale textures

    Tiberiu Tesileanu et al.
    An optimization principle allows natural-image data to predict human sensitivity to synthetic, un-natural textures with multiple gray levels.
