摘要: Previous investigations have revealed sex-specific differences in brain morphometry. The effect of sex on cortical thickness may be influencing cognitive between sexes. With this exploratory study, we aimed to investigate the MRI-based cerebral cortex morphometry healthy young volunteers and how variability measures might affect functioning men women. 76 (45 31 women) underwent a 1.5 T MR scan 53 them completed comprehensive battery. Overall no gross significant sexes were found thickness, surface area curvature indexes. However, there was group by hemisphere interaction total (F(1,72)=5.02; p=0.03). A greater leftward asymmetry observed males. Only females show associations (IQ executive functioning). In conclusion, our findings do not support notion sexual dimorphism mantle morphology. results also suggest that but
