    Impaired adaptation of learning to contingency volatility in internalizing psychopathology

    Christopher Gagne, Ondrej Zika ... Sonia J Bishop
    Hierarchical modeling of internalizing symptoms and task performance reveals that difficulty adapting probabilistic learning to second-order uncertainty is common to anxiety and depression and holds across rewarding and punishing outcomes.

    Combining hypothesis- and data-driven neuroscience modeling in FAIR workflows

    Olivia Eriksson, Upinder Singh Bhalla ... Jeanette Hellgren Kotaleski
    Increased usability and validity of neuroscience models, through FAIR workflows for the whole modeling process, including data and model management, parameter estimation, uncertainty quantification, and model analysis.
    1. Neuroscience

    Modulation of dopamine D1 receptors via histamine H3 receptors is a novel therapeutic target for Huntington's disease

    David Moreno-Delgado, Mar Puigdellívol ... Peter J McCormick
    Progression of Huntington's disease can be slowed by altering dopamine signalling through the Dopamine 1 receptor - Histamine 3 receptor heteromer.

    Evidence for dopaminergic involvement in endogenous modulation of pain relief

    Simon Desch, Petra Schweinhardt ... Susanne Becker
    Endogenous modulation of pain relief perception is based on its motivational content and enhanced by increased dopamine availability with no significant effects of a pharmacological opioidergic manipulation in healthy volunteers.
    1. Neuroscience

    Catecholaminergic modulation of meta-learning

    Jennifer L Cook, Jennifer C Swart ... Roshan Cools
    A human psychopharmacology study reveals that a drug that affects the dopamine and noradrenaline systems enhances people's ability to adapt their learning rate to suit the volatility of the environment.

    1. Neuroscience

    Transcriptomics-informed large-scale cortical model captures topography of pharmacological neuroimaging effects of LSD

    Joshua B Burt, Katrin H Preller ... John D Murray
    Computational models of large-scale cortical dynamics, integrating gene expression mapping to pattern pharmacological modulation across cortex, capture inter-areal topographies of functional connectivity alterations induced by lysergic acid diethylamide, providing a framework for simulating effects of pharmacology in the human brain.
    1. Neuroscience

    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.
    1. Neuroscience

    Anterior insular cortex plays a critical role in interoceptive attention

    Xingchao Wang, Qiong Wu ... Jin Fan
    Anterior insular cortex activity predicts how well we attend to our bodily signals, while lesions to this brain region disrupt this ability.
    1. Neuroscience

    Chronic activation of a negative engram induces behavioral and cellular abnormalities

    Alexandra L Jellinger, Rebecca L Suthard ... Steve Ramirez
    Repeatedly activating negative memory-bearing cells produces cellular and behavioral abnormalities.
