Abstract

Predictive coding models of brain processing propose that top-down cortical signals promote efficient neural signaling by carrying predictions about incoming sensory information. These "priors" serve to constrain bottom-up signal propagation where prediction errors are carried via feedforward mechanisms. Depression, traditionally viewed as a disorder characterized by negative cognitive biases, is associated with disrupted reward prediction error encoding and signaling. Accumulating evidence also suggests that depression is characterized by impaired local and long-range prediction signaling across multiple sensory domains. This review highlights the electrophysiological and neuroimaging evidence for disrupted predictive processing in depression. The discussion is framed around the manner in which disrupted generative predictions about the sensorium could lead to depressive symptomatology, including anhedonia and negative bias. In particular, the review focuses on studies of sensory deviance detection and reward processing, highlighting research evidence for both disrupted generative predictions and prediction error signaling in depression. The role of the monoaminergic and glutamatergic systems in predictive coding processes is also discussed. This review provides a novel framework for understanding depression using predictive coding principles and establishes a foundational roadmap for potential future research.

  • Mood disorders are typically managed with medications acting on the monoaminergic and glutamatergic systems.

    “mood disorders are typically managed with medications acting on the monoaminergic and glutamatergic systems”

    From Predictive coding in neuropsychiatric disorders: a systematic transdiagnostic review. (2025) · cites this paper as Gilbert et al., 2022

    The “Antidepressant Drugs and Predictive Processes” section says most approved antidepressants target the monoaminergic system and describes ketamine and esketamine as glutamatergic treatment options for depression. It does not establish that glutamatergic medications are *typically* used, or that this treatment pattern applies to mood disorders broadly rather than major depression. (LLM, conf=0.88)

  • Monoaminergic and glutamatergic systems play a critical role in mood, behavioral, and cognitive regulation, including predictive performance.

    “both playing a critical role in mood, behavioral, and cognitive regulation, including predictive performance (Gilbert et al., 2022; Goulty et al., 2023; Pal, 2021; Sanacora et al., 2008).”

    From Predictive coding in neuropsychiatric disorders: a systematic transdiagnostic review. (2025) · cites this paper as Gilbert et al., 2022

    The Monoaminergic Drugs section links monoamines to emotion, behavior, and cognition, while the Glutamatergic Drugs section links glutamate signaling to mood disorders and possible roles in predictive coding. But the Conclusion says further work is needed to understand how these systems support predictive signaling; the paper does not establish that both play a critical role in predictive performance generally.

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.
