Midbrain Dopamine Neurons Signal Preference for Advance Information about Upcoming Rewards

Open access

Abstract

The desire to know what the future holds is a powerful motivator in everyday life, but it is unknown how this desire is created by neurons in the brain. Here we show that when macaque monkeys are offered a water reward of variable magnitude, they seek advance information about its size. Furthermore, the same midbrain dopamine neurons that signal the expected amount of water also signal the expectation of information, in a manner that is correlated with the strength of the animal's preference. Our data show that single dopamine neurons process both primitive and cognitive rewards, and suggest that current theories of reward-seeking must be revised to include information-seeking.

  • Stimuli that predict reward have an inherent aspect of motivational significance; a liquid-deprived monkey treats a cue indicating forthcoming liquid as a type of reward in itself, even when this information has no bearing on task performance.

  • We used high-resolution (1-mm isotropic), rapid-repetition-time (1.378 s), accelerated ultrahigh-field (7T) fMRI to measure activity simultaneously across all five neuromodulatory nuclei and two interconnected cortical regions (AI and ACC).

  • All the neuromodulatory systems with their origins in VTA, SN, DRN, LC and VSN have at one time or another been proposed to reflect uncertainty or the potential for information gain.

    “all the neuromodulatory systems with their origins in the ventral tegmental area (VTA), substantia nigra (SN), dorsal raphe nucleus (DRN), locus coeruleus (LC) and ventral septal nucleus (VSN) have at one time or another been proposed to reflect uncertainty or the potential for information gain3,21–27”
  • All major neuromodulatory systems have been linked to uncertainty processing, but identifying a specific or preeminent contribution has been difficult.

  • Activity in individual neurons in both habenula and VTA reflects both the value of a stimulus in terms of the reward that it predicts and VoI.

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.
