    A cholinergic feedback circuit to regulate striatal population uncertainty and optimize reinforcement learning

    Nicholas T Franklin, Michael J Frank
    Computational modeling suggests that feedback between striatal cholinergic neurons and spiny neurons dynamically adjusts learning rates to optimize behavior in a variable world.

    Expansion and loss of sperm nuclear basic protein genes in Drosophila correspond with genetic conflicts between sex chromosomes

    Ching-Ho Chang, Isabel Mejia Natividad, Harmit S Malik
    Genetic conflicts between sex chromosomes during spermatogenesis may drive the rapid evolution, function, and turnover of some sperm nuclear basic proteins in Drosophila species.

    Hyperactivation of ERK by multiple mechanisms is toxic to RTK-RAS mutation-driven lung adenocarcinoma cells

    Arun M Unni, Bryant Harbourne ... Harold Varmus
    Cancer cells driven by mutations in KRAS or EGFR are dependent on DUSP6 to prevent ERK-induced cell death, creating a novel vulnerability for targeted therapy.

    Gene flow mediates the role of sex chromosome meiotic drive during complex speciation

    Colin D Meiklejohn, Emily L Landeen ... Daven C Presgraves
    Selfish genetic elements may either promote or prevent the evolution of reproductive barriers, depending on the extent of gene flow between species.

    Layer 6 ensembles can selectively regulate the behavioral impact and layer-specific representation of sensory deviants

    Jakob Voigts, Christopher A Deister, Christopher I Moore
    Changing which layer 6 neurons are active during sensory tasks disrupts the detection and encoding of changes, but still allows integration of sensory information in the absence of changes.

    Cortical encoding of acoustic and linguistic rhythms in spoken narratives

    Cheng Luo, Nai Ding
    In the processing of spoken narratives, bottom-up acoustic cues and top-down linguistic knowledge separately contribute to neural construction of linguistic units.

    Dual mechanisms of opioid-induced respiratory depression in the inspiratory rhythm-generating network

    Nathan A Baertsch, Nicholas E Bush ... Jan-Marino Ramirez
    Opioids cause hyperpolarization and pre-synaptic suppression among a subset of preBötzinger Complex neurons to impair respiratory rhythmogenesis.

    Corticostriatal dynamics encode the refinement of specific behavioral variability during skill learning

    Fernando J Santos, Rodrigo F Oliveira ... Rui M Costa
    Recordings from the mouse brain as animals learn a lever pressing task reveal how the motor system optimizes skill learning by reducing variability in those aspects of task performance that are essential for achieving a goal.

    High social status males experience accelerated epigenetic aging in wild baboons

    Jordan A Anderson, Rachel A Johnston ... Jenny Tung
    Among the factors that predict fitness in wild baboons, dominance rank in males, but not in females, is the best predictor of epigenetic aging.

    Neural encoding of actual and imagined touch within human posterior parietal cortex

    Srinivas Chivukula, Carey Y Zhang ... Richard A Andersen
    Single neurons in human posterior parietal cortex encode actual and imagined touch within a shared neural substrate.
