Brain reward circuitry beyond the mesolimbic dopamine system: a neurobiological theory

Open access
Ikemoto, Satoshi·2010·Neuroscience & Biobehavioral Reviews

Abstract

Reductionist attempts to dissect complex mechanisms into simpler elements are necessary, but not sufficient for understanding how biological properties like reward emerge out of neuronal activity. Recent studies on intracranial self-administration of neurochemicals (drugs) found that rats learn to self-administer various drugs into the mesolimbic dopamine structures-the posterior ventral tegmental area, medial shell nucleus accumbens and medial olfactory tubercle. In addition, studies found roles of non-dopaminergic mechanisms of the supramammillary, rostromedial tegmental and midbrain raphe nuclei in reward. To explain intracranial self-administration and related effects of various drug manipulations, I outlined a neurobiological theory claiming that there is an intrinsic central process that coordinates various selective functions (including perceptual, visceral, and reinforcement processes) into a global function of approach. Further, this coordinating process for approach arises from interactions between brain structures including those structures mentioned above and their closely linked regions: the medial prefrontal cortex, septal area, ventral pallidum, bed nucleus of stria terminalis, preoptic area, lateral hypothalamic areas, lateral habenula, periaqueductal gray, laterodorsal tegmental nucleus and parabrachical area.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The DAergic system, particularly the mesocorticolimbic pathway, is involved in drug addiction because DA modulates limbic and cortical sites for goal-directed behavior.

    “The role of the DAergic system (in particular the mesocorticolimbic pathway) in drug addiction derives from DA’s ability to modulate many of the limbic and cortical sites involved in goal-directed behavior (Fig. 1) [18, 28–31].”

  • The LHb is a source of anti-reward signals that influences reward-related DA neuron activity.

    “Studies conducted in recent years have identified the LHb as a source of anti-reward signals that plays an important role in determining the reward-related activity of DA neurons [18, 30, 68–70].”

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.
