    Mesolimbic confidence signals guide perceptual learning in the absence of external feedback

    Matthias Guggenmos et al.
    Neural confidence signals can take the role of reward signals and explain perceptual learning without external feedback as a form of internal reinforcement learning.
    1. Neuroscience

    Bottom-up and top-down influences at untrained conditions determine perceptual learning specificity and transfer

    Ying-Zi Xiong et al.
    Perceptual learning is specific because of the absence of bottom-up stimulation and top-down modulation at the untrained conditions.
    1. Neuroscience

    Reinforcement biases subsequent perceptual decisions when confidence is low, a widespread behavioral phenomenon

    Armin Lak et al.
    Confidence-dependent reinforcement learning is active and produces trial-to-trial choice updating even in well-learned perceptual decisions without explicit reward biases, across species and sensory modalities.

    GABA, not BOLD, reveals dissociable learning-dependent plasticity mechanisms in the human brain

    Polytimi Frangou et al.
    Combining GABA with fMRI measurements in the human brain uncovers distinct suppression mechanisms that optimize perceptual decisions through learning and experience-dependent plasticity in the visual cortex.

    Developmental deprivation-induced perceptual and cortical processing deficits in awake-behaving animals

    Justin D Yao, Dan H Sanes
    Developmental hearing loss causes perceptual deficits that are best explained by degraded auditory cortical encoding that is recorded during task performance.

    Visuomotor learning from postdictive motor error

    Jana Masselink, Markus Lappe
    Visual, motor, and forward model gains learn from a postdictive update of space to keep perception and saccadic motor function aligned.

    Value generalization in human avoidance learning

    Agnes Norbury et al.
    Individual differences in generalization of aversive value (but not safety information) during human active avoidance learning specifically predict experience of anxiety and intrusive thoughts.
    1. Neuroscience

    Standardized and reproducible measurement of decision-making in mice

    The International Brain Laboratory et al.
    A standard for complex mouse behavior that can be successfully reproduced across laboratories, along with open-access data and tools to implement provide a resource for reproducibility through collaborative open-science approaches.

    Nostril-specific and structure-based olfactory learning of chiral discrimination in human adults

    Guo Feng, Wen Zhou
    Training-induced perceptual gain in the discrimination between odor enantiomers is nostril-specific and structure-based, indicating that early olfactory processing of the chemical features of unirhinal input remains plastic in human adults.
    1. Neuroscience

    Ongoing, rational calibration of reward-driven perceptual biases

    Yunshu Fan et al.
    The rational application of heuristic learning strategies and satisficing goals accounted for near-optimal decisions that combined reward and noisy visual information by well-trained monkeys.
