Danek & Flanagin's magic-trick fMRI paradigm decomposed insight into two
sub-processes and asked whether they are neurally the same. Their answer:
"partially overlapping but distinct networks of brain activity were recruited
for cognitive conflict and restructuring." Conflict was carried by "posterior,
predominantly visual brain activity… related to prediction error, attention…
and the default brain state"; restructuring by "a highly distributed pattern
of brain activity in regions of the default mode, executive control networks,
and salience networks."

The named exception to that dissociation: "the angular gyrus, middle temporal
gyrus, frontal eye fields and DLPFC were all active in both cognitive conflict
and restructuring, suggesting a more overarching role of these regions in the
whole insight process." So a handful of regions are *phase-general* while the
bulk of each phase's network is *phase-specific*.

Why this is on the vault's shelf, distinct from
[[claim-cognitive-conflict-prerequisite-for-restructuring]] (which is about
conflict being *necessary*): this is about **separability**. Conflict and
restructuring being largely distinct networks is neural evidence that
detecting a misfit and reorganizing around it are two operations, not one —
directly relevant to whether the vault should treat gap-detection (the
conflict analogue, [[moc-knowledge-gap-detection]]) and consolidation (the
restructuring analogue, [[question-consolidation-pass-vs-revisit-protocol]])
as separate mechanisms rather than one pass. Honest scope: one paper's
within-study contrast (incongruent-vs-congruent cues; correct-vs-incorrect
solutions), not an independently replicated result. Prediction-error appears
here too as the conflict driver — the same trigger as
[[claim-schema-change-four-mode-taxonomy]] and
[[claim-p3-indexes-prediction-error-schema-updating]]. Entity candidates
flagged not decided: Danek, Flanagin.
