Abstract

When deciding between different options, individuals are guided by the expected (mean) value of the different outcomes and by the associated degrees of uncertainty. We used functional magnetic resonance imaging to identify brain activations coding the key decision parameters of expected value (magnitude and probability) separately from uncertainty (statistical variance) of monetary rewards. Participants discriminated behaviorally between stimuli associated with different expected values and uncertainty. Stimuli associated with higher expected values elicited monotonically increasing activations in distinct regions of the striatum, irrespective of different combinations of magnitude and probability. Stimuli associated with higher uncertainty (variance) elicited increasing activations in the lateral orbitofrontal cortex. Uncertainty-related activations covaried with individual risk aversion in lateral orbitofrontal regions and risk-seeking in more medial areas. Furthermore, activations in expected value-coding regions in prefrontal cortex covaried differentially with uncertainty depending on risk attitudes of individual participants, suggesting that separate prefrontal regions are involved in risk aversion and seeking. These data demonstrate the distinct coding in key reward structures of the two basic and crucial decision parameters, expected value, and uncertainty.

  • The dopaminergic VTA is implicated in rewarding aspects of addictive drugs and also participates in signaling aversion and lack of expected reward.

    “While the DAergic VTA has been widely implicated in the rewarding aspects of addictive drugs, it has also been shown to participate in the signaling of aversion and lack of expected reward (Schultz et al. 1998; Ungless et al. 2004; Tobler et al. 2007; De Biasi and Dani 2011).”

    From Nicotine Withdrawal (2015) · cites this paper as Tobler et al. 2007

    The Discussion (page unavailable) says dopamine-neuron responses are stronger for cues predicting greater reward, supporting a general role in reward signaling. It does not establish that the VTA signals aversion or the absence of an expected reward, or address the rewarding effects of addictive drugs. (LLM, conf=0.81)

  • When the medial orbitofrontal cortex receives outcome-related signals during reward learning, a calculation of the outcome's expected value occurs.

    “For instance, when the medial orbitofrontal cortex receives outcome-related signals during reward learning, a calculation of the outcome’s expected value occurs (Tobler et al., 2007).”

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.
