Neural Circuitry of Salience and Reward Processing in Psychosis

Abstract

The processing of salient and rewarding stimuli is integral to engaging our attention, stimulating anticipation for future events, and driving goal-directed behaviors. Widespread impairments in these processes are observed in psychosis, which may be associated with worse functional outcomes or mechanistically linked to the development of symptoms. Here, we summarize the current knowledge of behavioral and functional neuroimaging in salience, prediction error, and reward. Although each is a specific process, they are situated in multiple feedback and feedforward systems integral to decision making and cognition more generally. We argue that the origin of salience and reward processing dysfunctions may be centered in the subcortex during the earliest stages of psychosis, with cortical abnormalities being initially more spared but becoming more prominent in established psychotic illness/schizophrenia. The neural circuits underpinning salience and reward processing may provide targets for delaying or preventing progressive behavioral and neurobiological decline.

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

  • Decision-making and learning impairments are core characteristics of a wide range of psychiatric disorders, including MDD, OCD, and schizophrenia, and are linked to their specific symptoms.

    “Decision-making and learning impairments are core characteristics of a wide range of psychiatric disorders — such as major depressive disorder (MDD), obsessive–compulsive disorder (OCD), and schizophrenia — and are linked to their specific symptoms.1–9”
  • Our findings are in line with previous literature that these patients generally possess an impairment in reward anticipation and effort-based decision-making.

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.
