Abstract:
Objective To study the correlation between novelty seeking(NS) personality of healthy young individuals and fractional anisotropy (FA) with voxel-based analysis (VBA) of diffusion tensor imaging(DTI),and explore the microstructure of white matter of personality.Methods Total 333 healthy right handed volunteers completed the Chinese version of the TPQ and the Beck Depression Inventory(BDI),and then finished 3D T1 structure scan,DTI scan.All preprocessed DTI datum was analyzed with SPM8 soft ware in partial correlation analysis,using age and depression scores as controlled variable.The correlation studied between NS and FA (a voxel significance threshold P ＜ 0.001 and a cluster extent threshold of 30 voxels).Results NS score of men and women were 14.55 ± 4.66 and 14.08 ± 5.42 points,and the difference between the two groups was not statistically significant (t =0.81,P=0.46).BDI score of men were higher than that of women (t =3.10,P=0.002),which were 9.23 ± 7.90 and 6.76 ± 5.79 points respectively.NS correlated negatively with FA of the right inferior frontal gyrus,and the right supramarg(i)nal gyrus(P ＜ 0.001).Conclusion NS personality has specific microstructure background of white matter.
