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

Mentions: We first examined the generation phase, by comparing the generation of new poems and recitation of memorized poems conditions directly using GLM, in all subjects (Fig. 1; Supporting Information Table 3). The generation phase was characterized by a dissociated pattern: increases in the MPFC, broadly extending from the frontal pole into the presupplementary motor area, were accompanied by decreases in the DLPFC, intraparietal sulcus (IPS), and precuneus bilaterally. The generation phase was also associated with increased activity in perisylvian areas, including the bilateral inferior front gyrus (IFG), left middle temporal gyrus (MTG), and superior temporal sulcus (STS) and other language‐related areas in the left hemisphere, including the supramarginal, angular and fusiform gyri. Generation of new poems was also associated with increases in mesial temporal areas, including the parahippocampal gyrus, hippocampus, and amygdala bilaterally and subcortical areas in the left hemisphere, including the body of the caudate nucleus, posterior putamen, and anterior, medial dorsal, and pulvinar thalamic nuclei.
