Preferential activation of midbrain dopamine neurons by appetitive rather than aversive stimuli

Abstract

Midbrain dopamine systems are crucially involved in motivational processes underlying the learning and execution of goal-directed behaviour. Dopamine neurons in monkeys are uniformly activated by unpredicted appetitive stimuli such as food and liquid rewards and conditioned, reward-predicting stimuli. By contrast, fully predicted stimuli are ineffective, and the omission of predicted reward depresses their activity. These characteristics follow associative-learning rules, suggesting that dopamine responses report an error in reward prediction. Accordingly, neural network models are efficiently trained using a dopamine-like reinforcement signal. However, it is unknown whether the responses to environmental stimuli concern specific motivational attributes or reflect more general stimulus salience. To resolve this, we have compared dopamine impulse responses to motivationally opposing appetitive and aversive stimuli. In contrast to appetitive events, primary and conditioned non-noxious aversive stimuli either failed to activate dopamine neurons or, in cases of close resemblance with appetitive stimuli, induced weaker responses than appetitive stimuli. Thus, dopamine neurons preferentially report environmental stimuli with appetitive rather than aversive motivational value.

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.
