Primes¶
- Cross-Dimensional Leakage
- Reputation and neuroimaging: an organisation's reputation halo contaminates ratings of unrelated products; scanner drift and physiological noise inflate apparent functional connectivity across voxel time series.
This sourceShows a shared artefact (head motion) systematically inflates apparent functional-connectivity correlations across many voxel/region time series at once — the shared-channel contamination of cross-dimensional structure in neuroimaging.
Supported in partVerified against the work's full text
Shows that subject head motion, a shared artefact, produces systematic spurious functional-connectivity correlations; it does not cover scanner drift, physiological noise or reputation halo.
“These changes cause systematic but spurious correlation structures throughout the brain.”

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
