    Extracting grid cell characteristics from place cell inputs using non-negative principal component analysis

    Yedidyah Dordek, Daniel Soudry ... Dori Derdikman
    Computational modeling of the brain’s navigation system reveals that place cells can drive the formation of hexagonal patterns experimentally observed in grid cells activity.

    Non-linear developmental trajectory of electrical phenotype in rat substantia nigra pars compacta dopaminergic neurons

    Martial A Dufour, Adele Woodhouse ... Jean-Marc Goaillard
    The development of the electrical phenotype of neurons can be precisely quantified and dissected using a combination of multi-variate statistical analyses and a systematic electrophysiological characterization of electrical properties.

    Decoding the brain state-dependent relationship between pupil dynamics and resting state fMRI signal fluctuation

    Filip Sobczak, Patricia Pais-Roldán ... Xin Yu
    The variability of the pupil–fMRI relationship was characterized through a combination of clustering and prediction methods, which revealed brain state-specific subcortical and neuromodulatory activation patterns reflected in pupil dynamics.

    Common genetic variations in telomere length genes and lung cancer: a Mendelian randomisation study and its novel application in lung tumour transcriptome

    Ricardo Cortez Cardoso Penha, Karl Smith-Byrne ... James D Mckay
    A novel Mendelian randomisation framework unravels one gene expression component, correlated with proliferation and genome stability-related features, associated with telomere length in lung adenocarcinoma tumours, which provides insights into how telomere length influences the genetic basis of lung cancer aetiology.

    Sparse dimensionality reduction approaches in Mendelian randomisation with highly correlated exposures

    Vasileios Karageorgiou, Dipender Gill ... Verena Zuber
    Applied and computational results show how dimensionality reduction approaches can help in grouping correlated genetic variant-exposure associations and improve causal inference in the Mendelian randomisation framework.
    1. Neuroscience

    Social dominance mediates behavioral adaptation to chronic stress in a sex-specific manner

    Stoyo Karamihalev, Elena Brivio ... Alon Chen
    Social dominance has opposing effects on behavior following stress in male vs. female mice indicating an important role in sex differences in the stress response.

    Characterisation of molecular motions in cryo-EM single-particle data by multi-body refinement in RELION

    Takanori Nakane, Dari Kimanius ... Sjors HW Scheres
    Multi-body refinement in RELION allows high-resolution reconstruction and visualisation of molecular motions in cryo-EM single-particle data sets with continuous forms of structural heterogeneity.

    Genetic insights into ossification of the posterior longitudinal ligament of the spine

    Yoshinao Koike, Masahiko Takahata ... Shiro Ikegawa
    A GWAS meta-analysis for OPLL identified fourteen significant genomic loci and a subsequent Mendelian randomization study provided genetic evidence for a causal effect of obesity on the pathogenesis of OPLL, especially one of its subtypes, thoracic OPLL.
