    Using the past to estimate sensory uncertainty

    Ulrik Beierholm et al.
    For perceptual inference, human observers do not estimate sensory uncertainty instantaneously from the current sensory signals alone, but by combining past and current sensory inputs consistent with a Bayesian learner.

    The role of premature evidence accumulation in making difficult perceptual decisions under temporal uncertainty

    Ciara A Devine et al.
    Temporal uncertainty interferes with the timely onset of evidence accumulation in perceptual decision making prompting the brain to rely instead on statistical regularities in the temporal structure of the environment.

    A statistical framework for assessing pharmacological responses and biomarkers using uncertainty estimates

    Dennis Wang et al.
    Quantification of uncertainty in drug dose-responses provides a more robust metric for differentiating drugs and identifying biomarkers of response.

    Neural basis of somatosensory target detection independent of uncertainty, relevance, and reports

    Pia Schröder et al.
    Neural correlates of somatosensory target detection are restricted to secondary somatosensory cortex, whereas activity in insular, cingulate, and motor regions reflects stimulus uncertainty and overt reports.

    Neural markers of predictive coding under perceptual uncertainty revealed with Hierarchical Frequency Tagging

    Noam Gordon et al.
    The novel neural marker for the integration of top-down predictions and bottom-up signals in perception elucidates uncertainty in perceptual inference and provides evidence for the predictive coding account of perception.

    Impaired adaptation of learning to contingency volatility in internalizing psychopathology

    Christopher Gagne et al.
    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.

    Tuning movement for sensing in an uncertain world

    Chen Chen et al.
    Animals work in a world full of surprises, where using energy to position sensors proportional to the location's expected information avoids the pitfalls of positioning them at the information maxima.

    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.

    Uncertainty leads to persistent effects on reach representations in dorsal premotor cortex

    Brian M Dekleva et al.
    When Rhesus monkeys plan reaching movements of which they are not fully confident, a particular area of the brain represents both the chosen action as well as alternate movements, perhaps as an aid for error correction or learning.
