| Abstract: | Objective:To investigate the relationship between activity of fronto-parietal lobe cortex in working memory task and the fibrous tract anisotropy of white matter in the same region of normal children with blood oxygen leve-dependent functional MRI(BOLD fMRI) and diffusion tensor imaging(DTI) techniques.Methods:Twelve healthy children volunteers(6 males,6 females,mean age 11.4 years) were recruited.Paced visual serial addition test(PVSAT) was used as the mode of stimulation,BOLD fMRI was performed in all 12 ... |
