    Striatal action-value neurons reconsidered

    Lotem Elber-Dorozko, Yonatan Loewenstein
    The numerous reports in support of action-value representation in the striatum are based on statistical analyses that are subject to two critical confounds and, thus, this long-held belief of striatal action-value representation should be retested using different experiments and analyses.

    Robust and distributed neural representation of action values

    Eun Ju Shin et al.
    Action-value signals previously found in many brain areas can be accounted for neither by concurrent serial correlations in neural activity and action value nor by signals for other decision variables.

    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.

    Thalamocortical and corticothalamic pathways differentially contribute to goal-directed behaviors in the rat

    Fabien Alcaraz et al.
    Adaptive decision-making critically depends on antiparallel flows conveying distinct information within thalamocortical circuits, highlighting directionality of functional exchanges as a neural principle potentially at play in virtually any brain circuit with reciprocal projections.

    Orbital frontal cortex updates state-induced value change for decision-making

    Emily T Baltz et al.
    Orbital frontal cortex projection neuron activity is necessary to update state-dependent value change to control model-based behavior.

    Mediodorsal thalamus is required for discrete phases of goal-directed behavior in macaques

    Evan Wicker et al.
    Transient suppression of activity in the macaque mediodorsal thalamus impairs adjustment of secondary reinforcer values and disrupts appropriate action selection in a reinforcer devaluation task; this profile is distinct from that of amygdala or subregions of orbitofrontal cortex.

    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.

    Value-based attentional capture affects multi-alternative decision making

    Sebastian Gluth et al.
    Speeded value-based decisions between two options can be affected by a third, high-value distractor that captures attention and slows down the choice process.

    Distinct roles of striatal direct and indirect pathways in value-based decision making

    Shinae Kwak, Min Whan Jung
    The direct and indirect pathways of the dorsal striatum play indispensable roles in value-dependent action selection and value learning, respectively.
    1. Neuroscience

    Reward-based training of recurrent neural networks for cognitive and value-based tasks

    H Francis Song et al.
    A two-part neural network models reward-based training and provides a unified framework in which to study diverse computations that can be compared to electrophysiological recordings from behaving animals.
