Brain activity and connectivity during poetry composition: Toward a multidimensional model of the creative process.

Liu S, Erkkinen MG, Healey ML, Xu Y, Swett KE, Chow HM, Braun AR - Hum Brain Mapp (2015)

Bottom Line: Distinct activation patterns were associated with generation and revision, two major phases of the creative process.Experts showed significantly stronger deactivation of DLPFC/IPS during generation, suggesting that they may more effectively suspend cognitive control.Quality of poetry, assessed by an independent panel, was associated with divergent connectivity patterns in experts and novices, centered upon MPFC (for technical facility) and DLPFC/IPS (for innovation), suggesting a mechanism by which experts produce higher quality poetry.

Brain activity associated with the revision phase.Statistical t map of RevNewPoem‐GenNewPoem on a 3D brain surface (A) and axial slices (B) (FWE < 0.05). t‐scores are rendered in colors ranging from negative (violet) to positive (yellow) as indicated by the accompanying color bar.

hbm22849-fig-0002: Brain activity associated with the revision phase.Statistical t map of RevNewPoem‐GenNewPoem on a 3D brain surface (A) and axial slices (B) (FWE < 0.05). t‐scores are rendered in colors ranging from negative (violet) to positive (yellow) as indicated by the accompanying color bar.

Mentions: To identify differences between the generation and revision phases (Fig. 2; Supporting Information Table 4), we directly subtracted GenNewPoem from RevNewPoem. In contrast to significant deactivations of the DLPFC and IPS in both hemispheres during the generation phase (Fig. 1), activity in these areas was significantly greater during the revision phase.
