The study of gender differences of the resting-state fMRI by using regional homogeneity

Objective:To explore the gender differences of the resting-state fMRI from the perspective of local consistency. Methods:The resting-state fMRI were performed to the 21healthy volunteers and obtained the individual activation figure and group activation figure by using regional homogeneity;then employed two-sample t-test to the group activation figure.Results: Compared with the female,the right occipital lobe lingual gyrus(BA18),the left side of the cerebellum,the right superior temporal gyrus(BA19),the right inferior temporal gyrus(BA20),the left inferior parietal lobule(BA22),the right precuneus(BA7),the cingulate gyrus of the left side(BA31),the out side after the left frontal gyrus(BA9),the right amount of back to back(BA6),the left supra-marginal gyrus(BA40)and the right anterior cingulate cortex(BA24)were statistically significant;the largest and the strength strongest intensity brain activational area was the right occipital lobe lingual gyrus(BA18).Contrasted to the male,there were statistical differences in the right inferior temporal gyrus(BA20),the left inferior temporal gyrus(BA20),pons,the left side of the cerebellum,the left temporal area(BA38),right frontal pole area(BA10),left parahippocampal gyrus(BA34)and the left post-central gyrus(BA3);the largest brain activational area was the right frontal area(BA10)and the strength strongest intensity area was pons.Conclusion:The gender differences of the resting-state fMRI was statistically significant.
