Capture: What does the Danek & Flanagin (2019) paper report about the roles of the angular gyrus and middle temporal gyrus across the conflict and restructuring phases of insight problem solving?
Context
This capture verifies a specific, harvested topic about Danek & Flanagin's 2019 fMRI paper on insight problem solving, specifically what it reports about the angular gyrus and middle temporal gyrus across the paper's two proposed sub-processes of insight: cognitive conflict and restructuring. The paper was located, its identity confirmed, and its abstract and Discussion-section text pulled directly from the peer-reviewed, open-access full text hosted on PubMed Central (NCBI PMC) — a Tier 1 venue (the journal's own published article text, mirrored verbatim by a public archive, not a secondary summary).
Claim 1: The paper is "Cognitive conflict and restructuring: The neural basis of two core components of insight," by Amory H. Danek and Virginia L. Flanagin, published in AIMS Neuroscience, 6(2):60–84, 21 May 2019
Claim type: historical/bibliographic Sourcing floor: Tier 3–4 acceptable; Tier 1 achieved
The paper's identity, authorship, journal, and publication date were confirmed directly from the article's own abstract page on PMC.

Claim 2: The paper's design breaks the insight process (elicited via magic-trick "how was this done?" problems) into two components — cognitive conflict and restructuring — and used incongruent-vs-congruent cues to manipulate conflict and correct-vs-incorrect solutions to isolate restructuring
Claim type: technical-mechanism (study design) Sourcing floor: Tier 1–2 required Source tier achieved: Tier 1 — verbatim abstract text from the publisher-hosted, PMC-mirrored article
"Broadening the traditional approach, we propose to tackle this question by presenting magic tricks to participants and asking them to find out the secret method used by the magician. Combining this approach with cueing in an fMRI experiment, we were able to break down the insight process into two underlying components: cognitive conflict and restructuring. During cognitive conflict, problem solvers identify incongruent information that does not match their current mental representation. In a second step this information is restructured, thereby allowing them to correctly determine how the magic trick was done. We manipulated the occurrence of cognitive conflict by presenting two types of cues that lead participants to either maintain their perceptual belief (congruent cue) or to change their perceptual belief (incongruent cue) for the mechanism behind the magic trick."

Claim 3: The paper reports that cognitive conflict and restructuring recruited "partially overlapping but distinct" networks — conflict driven by posterior/visual activity linked to prediction error and attention, restructuring by a distributed pattern across default mode, executive control, and salience networks
Claim type: technical-mechanism Sourcing floor: Tier 1–2 required Source tier achieved: Tier 1 — verbatim abstract text
"We found that partially overlapping but distinct networks of brain activity were recruited for cognitive conflict and restructuring. Posterior, predominantly visual brain activity during cognitive conflict reflected processes related to prediction error, attention to the relevant cue-specific sensory domain, and the default brain state. Restructuring on the other hand, showed a highly distributed pattern of brain activity in regions of the default mode, executive control networks, and salience networks."

Claim 4 (core question): The angular gyrus and middle temporal gyrus were active in both the cognitive-conflict and restructuring phases, which the authors interpret as these regions playing an overarching, phase-general role across the whole insight process — not a role specific to either phase alone
Claim type: technical-mechanism (this is the load-bearing claim the topic asks about) Sourcing floor: Tier 1–2 required Source tier achieved: Tier 1 — verbatim text, independently confirmed in both the abstract and the Discussion section
Abstract, final sentence:
"The angular gyrus and middle temporal gyrus were active in both cognitive conflict and restructuring, suggesting that these regions are important throughout the insight problem solving process."
Discussion section (section 4.2, "Neural correlates of restructuring" — the sentence appears near the close of that section rather than under a separate heading of its own):
"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."
Also in the Discussion, on the angular gyrus specifically:
"The left angular gyrus (AG) has been found in insight problem solving in a comparable way."

| exact_quote | see three quoted blocks above (abstract; Discussion §4.2; Discussion on left AG) |
This was cross-checked with two independent fetches of the same PMC full text (one asking generally for AG/MTG-relevant passages, one asking specifically for the Discussion paragraph making this argument); both returned the identical "were all active in both cognitive conflict and restructuring, suggesting a more overarching role" sentence, which supports treating it as an accurate rendering of the source's own wording rather than a fetch-tool paraphrase artifact.
Answer to the core question
Danek & Flanagin (2019) report that the angular gyrus and middle temporal gyrus are not phase-specific within their two-component model of insight. Rather than one region belonging to cognitive conflict and the other to restructuring, both regions showed significant activity in both phases — the paper states this explicitly, in near-identical wording, in both the abstract and the Discussion. The authors' own interpretation (Discussion §4.2) is that this cross-phase activation, shared also with the frontal eye fields and DLPFC, indicates "a more overarching role of these regions in the whole insight process," rather than a role tied to conflict-detection or to restructuring specifically. This sits alongside the paper's broader finding that conflict and restructuring otherwise recruit "partially overlapping but distinct" networks (conflict: posterior/visual, prediction-error- and attention-related; restructuring: a distributed default-mode/executive-control/salience-network pattern) — the angular gyrus and middle temporal gyrus are the explicitly named exception to that dissociation, appearing in both.
Further leads
- Table 1 and Table 2 of the paper (referenced in the Results as containing the specific cluster coordinates/statistics for the angular-gyrus and middle-temporal-gyrus activations under each contrast) were not independently retrieved in tabular form this session — only prose renderings via the fetch tool. If a future note needs the precise peak coordinates, cluster sizes, or statistical thresholds, pull Tables 1–2 directly from the PMC HTML or the AIMS Press HTML version (the latter,
https://www.aimspress.com/article/doi/10.3934/Neuroscience.2019.2.60, could not be fetched this session — the fetch tool flagged the domain as unverified for safety and declined to load it; PMC's mirror was used instead and is an equally valid Tier 1 copy of the same publisher text). - Section 4.1 ("Neural correlates of cognitive conflict") of the Discussion was not separately quoted verbatim here; only the abstract-level description of conflict's posterior/visual network was captured. A future capture on the conflict phase specifically should pull that section's exact wording.
