Age and sex effects on brain morphology.
(Clinical Trial;Journal Article)
1. Brain morphology can be assessed readily in vivo using magnetic resonance imaging (MRI). 2. In this study, the effects of age and sex on whole-brain morphology were examined using an operator-controlled computer-segmentation protocol. 3. Results indicated that age was associated with gray-matter volume reduction. 4. Brain-size differences between males and females were primarily attributable to white-matter volume. 5. This study confirms the importance of controlling for age and sex in brain-morphology studies.
