The short-latency dopamine signal: a role in discovering novel actions?

Redgrave, Peter, Gurney, Kevin·2006·Nature Reviews Neuroscience

Abstract

An influential concept in contemporary computational neuroscience is the reward prediction error hypothesis of phasic dopaminergic function. It maintains that midbrain dopaminergic neurons signal the occurrence of unpredicted reward, which is used in appetitive learning to reinforce existing actions that most often lead to reward. However, the availability of limited afferent sensory processing and the precise timing of dopaminergic signals suggest that they might instead have a central role in identifying which aspects of context and behavioural output are crucial in causing unpredicted events.

  • The magnitude of dopaminergic responses to unrewarded visual stimuli in primates is significantly more robust in rewarded environments.

    “However, the magnitude of these responses is significantly more robust in rewarded environments, suggesting that dopaminergic responses to sensory stimuli primarily serve to promote interaction with potentially rewarding objects (Kobayashi and Schultz, 2014) or enable novel action discovery that could lead to reward (Redgrave and Gurney, 2006).”

  • Recognition of the two-component structure of phasic dopamine responses may resolve earlier controversies that suggested an attentional rather than rewarding role of the dopamine prediction-error signal.

    “Recognition of the two-component structure of phasic dopamine responses may also resolve earlier controversies, which suggested an attentional rather than rewarding role of the dopamine prediction-error signal64,65 on the basis of activations following exposure to physically salient stimuli16,20 and punishers24.”
  • Novelty acts as an exploration bonus in reward seeking tasks and is encoded in dopamine cells as an intrinsic bonus for exploration.

    “Novelty has been proposed to act as an exploration bonus in reward seeking tasks (Wittmann et al., 2008), and to be encoded in dopamine cells as an intrinsic bonus for exploration (Redgrave and Gurney, 2006).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
