Correlational studies of individual differences in creative ability and functional connectivity (2017-2018)

Study	Sample Size	MRI Data	Creativity Task(s)	Network Analysis	Results
Beaty et al. (2018)	n = 163	Task fMRI	AUT (originality)	Connectome-based predictive modeling	Network connectivity strength predicted verbal creativity in 4 datasets
Liu et al. (2018)*	n = 236	Resting-state fMRI (and genetic data)	TTCT-V (composite)	Connectome-based predictive modeling	Network connectivity strength predicted verbal creativity in 2 datasets
Chen et al. (2018)*	n = 159	Structural MRI (2-3 timepoints)	TTCT-V (composite)	Longitudinal VBM	ECN and FTN gray matter maturation predicted future verbal creativity
Zhu et al. (2017)*	n = 282	Resting-state fMRI	TTCT-V (composite) and TTCT-F (composite)	ICA (mediation)	ECN mediated relation between DN and verbal, figural creativity
Sun et al. (2018)*	n = 574	Resting-state fMRI	TTCT-V (composite)	Temporal variability of FC	DN between- and within-network FC variability correlated with verbal creativity
Bendetowicz et al. (2018)	n = 29 frontal patients, n = 54 controls	Structural MRI (lesion mapping)	CAT-V and FGAT	Voxel-based lesion-deficit mapping; disconnection-deficit mapping; network-based lesion deficit	MPFC (DMN) lesion disrupted remote concept generation; RLPFC (ECN) lesion disrupted remote concept combination but not generation
Gao et al. (2017)**	n = 22 HCG, n = 22 LCG	Resting-state fMRI	TTCT-F (composite)	Voxel-wise whole-brain FCS; seed-to-voxel; graph theory	HCG showed greater FCS across regions of multiple networks; network efficiency correlated with figural creativity score
Kenett et al. (2018)	n = 416	DTI	TTCT-V (composite)	Network Control Theory	Network controllability of DLPFC (ECN) and other regions correlated with verbal creativity score
Li et al. (2017)**	n = 22 HCG, n = 22 LCG	Resting-state fMRI	TTCT-F (composite)	ICA; Dynamic FC	HCG showed more frequent transitions between brain states
Takeuchi et al. (2017)	n = 1277	Resting-state fMRI	S-A creativity test	ReHO; seed-to-voxel; fALFF	Creativity score in females correlated with ReHo of MTG (DMN); RSFC between MPFC (DMN) and IFG (ECN); and fALFF in precuneus (DMN), MTG (DMN), and other regions
