Gray matter correlates of creative potential: a latent variable voxel-based morphometry study.

Jauk E, Neubauer AC, Dunst B, Fink A, Benedek M - Neuroimage (2015)

Bottom Line: The results confirmed and extended previous research: rGMV in the precuneus was associated with ideational originality, but not with ideational fluency.In addition, we found ideational originality to be correlated with rGMV in the caudate nucleus.The results indicate that the ability to produce original ideas is tied to default-mode as well as dopaminergic structures.

Mentions: Fig. 1 displays the results of the voxelwise whole-brain multiple regression analysis. Given a cluster size threshold of k > 524 voxels, we observed significant positive associations between ideational originality and rGMV in the precuneus (x, y, z = 7.5, − 45.0, 45.0; t = 4.15; k = 1270) and in the left striatum (x, y, z = − 13.5, − 4.5, 12.0; t = 4.10; k = 598). While the striatal effect was observed only in the left hemisphere, the effect in the precuneus was lateralized to the right hemisphere (with 706 voxels being in the right and 476 in the left precuneus). No negative effects were observed for ideational originality. For ideational fluency, no significant effects were observed. For intelligence, we observed a positive effect in the right posterior cingulate cortex/calcarine sulcus (x, y, z = 22.5, − 63.0, 7.5; t = 4.38; k = 1428). A negative association between intelligence and rGMV was observed in the (predominantly right) precuneus (x, y, z = 12.0, − 49.5, 48.0; t =  4.33; k = 1208). Similarly, openness showed a negative association with rGMV in the precuneus (x, y, z = 9.0, − 43.5, 43.5; t =  4.70; k = 1071).
