    The hippocampus encodes delay and value information during delay-discounting decision making

    Akira Masuda et al.
    Two distinct subpopulations of CA1 neurons that increased or decreased their firing rate during delay were identified, suggesting that they have distinct roles in the valuation process in the hippocampus.

    Time preferences are reliable across time-horizons and verbal versus experiential tasks

    Evgeniya Lukinova et al.
    People have stable time-preferences regardless of whether they are measured using a non-verbal experiential task, as is typical in animal experiments, or using a more traditional verbal task.

    The role of ventromedial prefrontal cortex in reward valuation and future thinking during intertemporal choice

    Elisa Ciaramelli et al.
    During decisions between smaller-immediate rewards and larger rewards available in the future, the ventromedial prefrontal cortex is critical to represent the value of rewards, not the future.

    Single caudate neurons encode temporally discounted value for formulating motivation for action

    Yukiko Hori et al.
    The dorsal part of the primate caudate head signals integrated multi-dimensional incentive factors essential for computing the motivation for action.

    The role of oxytocin in delay of gratification and flexibility in non-social decision making

    Georgia Eleni Kapetaniou et al.
    Oxytocin was found to significantly improve non-social decision making in a healthy sample, suggesting a domain-general function of the hormone, in contrast to its previously hypothesized social domain specificity.

    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.

    Rats exhibit similar biases in foraging and intertemporal choice tasks

    Gary A Kane et al.
    In both foraging and intertemporal choice tasks, rats prefer immediate rewards to delayed rewards, and this preference can be explained by a form of hyperbolic discounting.

    Testicular hormones mediate robust sex differences in impulsive choice in rats

    Caesar M Hernandez et al.
    Sex differences in impulsive decision making, such that males are less impulsive than females, are critically dependent upon testicular but not ovarian hormones.

    A specific role for serotonin in overcoming effort cost

    Florent Meyniel et al.
    A selective reuptake inhibitor shows a beneficial effect in healthy humans during an effort-benefit tradeoff task, mediated at the computational level by a specific alleviation of effort cost.

    Subthalamic, not striatal, activity correlates with basal ganglia downstream activity in normal and parkinsonian monkeys

    Marc Deffains et al.
    The spiking activity of the subthalamic nucleus, rather than the activity of striatal projection neurons, orchestrates basal ganglia downstream activity and output commands in health and Parkinson’s disease.
