Abstract

Dopamine neurons facilitate learning by calculating reward prediction error, or the difference between expected and actual reward. Despite two decades of research, it remains unclear how dopamine neurons make this calculation. Here we review studies that tackle this problem from a diverse set of approaches, from anatomy to electrophysiology to computational modeling and behavior. Several patterns emerge from this synthesis: that dopamine neurons themselves calculate reward prediction error, rather than inherit it passively from upstream regions; that they combine multiple separate and redundant inputs, which are themselves interconnected in a dense recurrent network; and that despite the complexity of inputs, the output from dopamine neurons is remarkably homogeneous and robust. The more we study this simple arithmetic computation, the knottier it appears to be, suggesting a daunting (but stimulating) path ahead for neuroscience more generally.

  • Dopaminergic signaling in the NAc has been widely studied for its involvement in motivational salience, behavioral reinforcement, and reward prediction error encoding.

    “Dopaminergic signaling in the NAc has been widely studied for its involvement in motivational salience, behavioral reinforcement, and reward prediction error encoding (Schultz et al., 2015; Berridge and Robinson, 2016; Watabe-Uchida et al., 2017; Berke, 2018).”

    In “Complexities in the dopamine signal” (page unavailable), the review says nucleus accumbens dopamine encodes reward prediction errors relatively faithfully in simple tasks. “Functions of dopamine prediction error signals” describes dopamine’s role in behavioral reinforcement, but does not specifically locate that finding in the accumbens. The review associates motivational-salience signals mainly with neurons in the lateral midbrain, particularly the substantia nigra pars compacta, rather than with accumbens dopamine.

  • D1-type dopamine receptor-expressing medium spiny neurons of the direct pathway project to and inhibit VTA GABAergic interneurons that inhibit VTA dopamine cells; activating them disinhibits dopamine projections to the forebrain.

    “As originally described in the dorsal striatum, MSNs expressing D1-type dopamine receptors, canonically considered the 'direct' pathway, project to and inhibit GABAergic interneurons within the VTA that, in turn, inhibit VTA dopamine releasing cells.Activation of D1-expressing MSNs thereby promotes activation of dopamine projections back to the forebrain by disinhibiting them [220].”
  • D2-type dopamine receptor-expressing medium spiny neurons of the indirect pathway project to ventral pallidum GABAergic cells that project to VTA interneurons; activating them inhibits dopamine projections by disinhibiting the interneurons that silence them.

    “In contrast, MSNs expressing D2-type dopamine receptors, canonically considered the 'indirect' pathway, project to GABAergic cells within the ventral pallidum, that then project to the interneurons within the VTA.Activation of D2-expressing MSNs thereby inhibits activation of dopamine projections back to the forebrain by disinhibiting the interneurons that silence them.”
  • Dopamine dynamics within the mesolimbic pathway play a central role in appetitive learning and approach behavior.

    “Dopamine dynamics within the mesolimbic pathway play a central role in appetitive learning and approach behavior5,6.”
  • According to reinforcement learning theory, the US response is a driver of learning, while the CS response is considered a consequence of learning.

    “given that, according to reinforcement learning theory, the US response is a driver of learning, while the CS response is considered a consequence of learning6,18–20.”

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.
