    Instructed knowledge shapes feedback-driven aversive learning in striatum and orbitofrontal cortex, but not the amygdala

    Lauren Y Atlas et al.
    While the striatum and orbitofrontal cortex learn about threats through verbal warnings, the amygdala learns only from direct experience, suggesting that the amygdala forms part of a specialized threat detection system.

    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.

    The influence of task outcome on implicit motor learning

    Hyosub E Kim et al.
    During a sensorimotor perturbation, task outcome may serve as a gain on implicit adaptation or provide a distinct error signal for a second, independent implicit learning process.

    Anatomical and functional organization of the human substantia nigra and its connections

    Yu Zhang et al.
    The human substantia nigra can be parcellated into three subdivisions that subserve emotional, cognitive and somatomotor function.

    A neurobiological association of revenge propensity during intergroup conflict

    Xiaochun Han et al.
    Intergroup conflict increases human endogenous oxytocin, which predicts the medial prefrontal activity associated with ingroup pain and propensity to seek revenge upon the outgroup.

    Closed-loop optogenetic activation of peripheral or central neurons modulates feeding in freely moving Drosophila

    Pierre-Yves Musso et al.
    The Sip-Triggered Optogenetic Behavior Enclosure (STROBE) produces robust behaviors via activation of peripheral or central neurons in the fly, and mimics key features of feeding driven by chemical taste ligands.

    optoPAD, a closed-loop optogenetics system to study the circuit basis of feeding behaviors

    José-Maria Moreira et al.
    The optoPAD system combines real-time behavioral analysis with optogenetic manipulations to study how animals adapt to dynamic gustatory environments and to identify the circuit basis of feeding.

    Computational mechanisms of curiosity and goal-directed exploration

    Philipp Schwartenbeck et al.
    Distinct computational levels of uncertainty compel agents to gain information about hidden states in the world (‘active inference’) or optimise their ‘world model’ as such (‘active learning’).

    Learning shapes the aversion and reward responses of lateral habenula neurons

    Daqing Wang et al.
    Neurons in the lateral habenula are activated by pain, bitterness and social defeat, and their responses are dynamically shaped by learning, suggesting a role in experience-dependent selection of behavioral actions to stressors.
