    A Bayesian model of context-sensitive value attribution

    Francesco Rigoli et al.
    The dependence of incentive value attribution on the anticipation of rewards within a given context is explained via a normative Bayesian account of how rewards map to incentive values.

    Complementary contributions of basolateral amygdala and orbitofrontal cortex to value learning under uncertainty

    Alexandra Stolyarova, Alicia Izquierdo
    Rat orbitofrontal cortex is required to accurately represent outcome distributions, whereas basolateral amygdala is necessary for the facilitation of learning in response to surprising events.

    Autocorrelation structure at rest predicts value correlates of single neurons during reward-guided choice

    Sean E Cavanagh et al.
    Variability in individual neurons' temporal receptive fields of integration is found to explain the heterogeneity of neuronal responses observed in prefrontal cortex during reward-guided decision making.

    Specialized areas for value updating and goal selection in the primate orbitofrontal cortex

    Elisabeth A Murray et al.
    Within the monkey orbitofrontal cortex, a posterior part learns new values, whereas an anterior part translates this knowledge into advantageous decisions.

    Preconditioned cues have no value

    Melissa J Sharpe et al.
    Preconditioned cues provide information about an associative model but do not, by default, trigger representations of value, either model-based or model-free.

    Parental effects alter the adaptive value of an adult behavioural trait

    Rebecca M Kilner et al.
    The adaptive value of social behaviour exhibited in adult life varies with conditions experienced in early life, and poorer conditions may promote conflict over cooperation.

    Dopamine neurons learn relative chosen value from probabilistic rewards

    Armin Lak et al.
    When learning the reward probability of novel cues, dopamine neurons convey dissociable value and novelty signals.
  1. Point of View: Priority of discovery in the life sciences

    Ronald D Vale, Anthony A Hyman
    Disclosing work prior to submission to a journal would benefit scientists seeking to be acknowledged for their discoveries.
  2. Point of View: How should novelty be valued in science?

    Barak A Cohen
    An over-emphasis on novelty is having detrimental effects on science.

    Midbrain dopamine neurons signal aversion in a reward-context-dependent manner

    Hideyuki Matsumoto et al.
    Dopamine neurons signal value prediction errors (VPEs) integrating information about both reward and aversion, in low reward contexts, whereas VPEs in some dopamine neurons are distorted in high reward contexts.
