    Global diversity and antimicrobial resistance of typhoid fever pathogens: Insights from a meta-analysis of 13,000 Salmonella Typhi genomes

    Megan E Carey, Zoe A Dyson ... Global Typhoid Genomics Consortium Group Authorship
    An analysis of the largest Salmonella Typhi genome collection to date (n=13,000) provides an updated overview of global genome diversity and antimicrobial resistance trends over time to inform public health action.

    Optimal policy for attention-modulated decisions explains human fixation behavior

    Anthony I Jang, Ravi Sharma, Jan Drugowitsch
    A normative decision-making model that incorporates an information-limiting attention bottleneck is able to qualitatively replicate human behavior and make novel predictions that are verified in data.

    Deciphering molecular heterogeneity and dynamics of human hippocampal neural stem cells at different ages and injury states

    Junjun Yao, Shaoxing Dai ... Tianqing Li
    A single-nucleus transcriptomic atlas reveals the molecular signatures and trajectory dynamics of the neurogenic lineage in the human hippocampus during neonatal development, adulthood, aging, and after injury.

    Focal seizures are organized by feedback between neural activity and ion concentration changes

    Damiano Gentiletti, Marco de Curtis ... Piotr Suffczynski
    Biophysically realistic computational model reveals how inhibitory interneurons initiate paroxysmal discharges and how changes in the ionic concentrations shape electrographic features of human seizures.

    Sensorimotor mechanisms selective to numerosity derived from individual differences

    Giovanni Anobile, Irene Petrizzo ... Guido Marco Cicchini
    Evidence for a selective sensorimotor brain mechanism responsible for translating sensory numerical information into the number of actions in a sequence.

    Wiring variations that enable and constrain neural computation in a sensory microcircuit

    William F Tobin, Rachel I Wilson, Wei-Chung Allen Lee
    Systematic and coordinated variations in morphology and connectivity can structurally tune a microcircuit's computation but non-systematic variably also exists, imparting "connection noise" that potentially limits processing performance.

    Basal ganglia output reflects internally-specified movements

    Mario J Lintz, Gidon Felsen
    The basal ganglia may preferentially influence movements based on internal goals rather than those guided by external stimuli.

    Localized hypoxia within the subgranular zone determines the early survival of newborn hippocampal granule cells

    Christina Chatzi, Eric Schnell, Gary L Westbrook
    Neural progenitors reside in relative low oxygen in the subgranular zone (SGZ), and the higher tissue oxygen levels that these cells must face as they migrate away from the hypoxic areas and differentiate appear to cause oxidative damage and an early phase of cell death.

    Minimal requirements for a neuron to coregulate many properties and the implications for ion channel correlations and robustness

    Jane Yang, Husain Shakil ... Steven A Prescott
    In order to homeostatically regulate many (n) properties at the same time, neurons must coadjust many (n + 1) ion channels with the appropriate ratios, which can lead to ion channel correlations and increased risk of regulation failure.

    Human intracranial recordings link suppressed transients rather than 'filling-in' to perceptual continuity across blinks

    Tal Golan, Ido Davidesco ... Rafael Malach
    The brain ensures that blinks do not disrupt vision by deleting signals that represent discontinuities in visual input, rather than by recreating the missing input.
