Gender Differences in White Matter Microstructure

Gender Differences in White Matter Microstructure

BACKGROUND Sexual dimorphism in human brain structure is well recognised, but little is known about gender differences in white matter microstructure. We used diffusion tensor imaging to explore differences in fractional anisotropy (FA), an index of microstructural integrity. METHODS A whole brain analysis of 135 matched subjects (90 men and 45 women) using a 1.5 T scanner. A region of intere...

Individual Differences in White Matter Microstructure Predict Mathematical Achievement

The current study uses diffusion tensor imaging to test whether individual differences in white matter predict performance on the math subtest of the preliminary Scholastic Aptitude Test (PSAT). Grade 10 and 11 PSAT scores were obtained from 30 young adults (ages 17-18) with wide-ranging math achievement levels. Tract based spatial statistics was used to examine the correlation between PSAT mat...

White Matter Microstructure in Idiopathic Craniocervical Dystonia

BACKGROUND Dystonias are hyperkinetic movement disorders characterized by involuntary muscle contractions resulting in abnormal torsional movements and postures. Recent neuroimaging studies in idiopathic craniocervical dystonia (CCD) have uncovered the involvement of multiple areas, including cortical ones. Our goal was to evaluate white matter (WM) microstructure in subjects with CCD using dif...
