    Oxytocin promotes coordinated out-group attack during intergroup conflict in humans

    Hejing Zhang et al.
    Humans intranasally administered the neuropeptide oxytocin waste less and earn more spoils during intergroup conflict because oxytocin enables group members to better coordinate strategic attacking of out-groups.

    Primate prefrontal neurons signal economic risk derived from the statistics of recent reward experience

    Fabian Grabenhorst et al.
    Neurons in prefrontal cortex track the variance of experienced rewards to guide economic decisions.

    Sequential selection of economic good and action in medial frontal cortex of macaques during value-based decisions

    Xiaomo Chen, Veit Stuphorn
    Whenever monkeys are required to choose between multiple options, neural responses indicate that they first select the desired outcome and then use this information to guide their actions.

    Homeostatic reinforcement learning for integrating reward collection and physiological stability

    Mehdi Keramati, Boris Gutkin
    A mathematical model built around the assumption that the desire to maintain internal homeostasis drives the behavior of animals, by affecting their learning processes, can explain many real-world behaviors, including some that might otherwise appear irrational.

    Medial orbitofrontal inactivation does not affect economic choice

    Matthew PH Gardner et al.
    Inactivation of the medial orbitofrontal cortex using an optogenetic approach did not affect behavior in rats on an iconic economic choice task.

    Efficient sampling and noisy decisions

    Joseph A Heng et al.
    An efficient coding theory for higher-level cognitive processes reveals that humans efficiently adapt to contextual distributions by economizing on environmental prior information.
    1. Neuroscience

    A human subcortical network underlying social avoidance revealed by risky economic choices

    Johannes Schultz et al.
    The subjective value of engaging in human social situations, and amygdala and nucleus accumbens activation and their connectivity during social decision-making, vary with social anxiety traits.

    Promoting subjective preferences in simple economic choices during nap

    Sizhi Ai et al.
    Neurocognitive processing during sleep selectively biases subjective preferences in simple economic choices when the sleeper is stimulated by covert, reward-associated cues.
    1. Neuroscience

    Multiple mechanisms link prestimulus neural oscillations to sensory responses

    Luca Iemi et al.
    Neural oscillations prior to a stimulus modulate the strength of early and late responses in opposite directions via distinct mechanisms.
    1. Neuroscience

    Alterations in the amplitude and burst rate of beta oscillations impair reward-dependent motor learning in anxiety

    Sebastian Sporn et al.
    State anxiety alters the dynamics of beta oscillations during reward-dependent motor learning, thereby impairing proper updating of motor predictions when learning in unstable environments.
