Abstract

Disruption of functional connectivity may be a key feature of bipolar disorder (BD) which reflects disturbances of synchronization and oscillations within brain networks. We investigated whether the resting electroencephalogram (EEG) in patients with BD showed altered synchronization or network properties. Resting-state EEG was recorded in 57 BD type-I patients and 87 healthy control subjects. Functional connectivity between pairs of EEG channels was measured using synchronization likelihood (SL) for 5 frequency bands (δ, θ, α, β, and γ). Graph-theoretic analysis was applied to SL over the electrode array to assess network properties. BD patients showed a decrease of mean synchronization in the alpha band, and the decreases were greatest in fronto-central and centro-parietal connections. In addition, the clustering coefficient and global efficiency were decreased in BD patients, whereas the characteristic path length increased. We also found that the normalized characteristic path length and small-worldness were significantly correlated with depression scores in BD patients. These results suggest that BD patients show impaired neural synchronization at rest and a disruption of resting-state functional connectivity.

  • In predictive coding terms, the connectivity differences in bipolar disorder might reflect inconsistent application of top-down constraints on emotional inference: sometimes too much (mania) and sometimes too little (depression).

    “In predictive coding terms, this might reflect inconsistent application of top-down constraints on emotional inference: sometimes too much (leading to an inflated, unfettered mood in mania) and sometimes too little (leading to depressive pessimism) (69, 70).”

    From Predictive coding and neurocomputational psychiatry: a mechanistic framework for understanding mental disorders (2026) · cites this paper as [70]

    The Discussion (Synchronization in functional brain networks of BD; page unavailable) reports disrupted resting-state connectivity, and the Discussion (Symptom-related effects on functional network organization; page unavailable) links network alterations to greater depressive symptoms. The paper does not interpret these findings as excessive versus insufficient top-down constraints on emotional inference in mania and depression. (LLM, conf=0.86)

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.
