Sexual Dimorphism in Human Brain Weight and Volume of Gray and White Matter in Normal and Neurodegenerative Subjects - A Stereological and Macroscopic Study
Purpose: This study is designed to determine the sex differences in brain weight and volume of left hemisphere and its gray and white matters in right-handed normal subjects and the right-handed subjects which were suffered from Alzheimer and Parkinson diseases. Materials and Methods: This study was performed on 72 normal human brains (38 male, 34 female), 11 brains suffered from Alzheimer (4 ...
متن کاملSpecific anatomic associations between white matter integrity and cognitive reserve in normal and cognitively impaired elders.
OBJECTIVES to investigate the associations between white matter (WM) integrity and cognitive reserve (CR) in healthy elders (HE), amnestic mild cognitive impairment (a-MCI), and Alzheimer's disease (AD). The authors studied correlations between CR and WM integrity in regions showing WM age-related effects or pathologic changes and tested the differences of slopes between groups. METHODS diffu...
متن کاملDetermination of Gray Matter (GM) and White Matter (WM) Volume in Brain Magnetic Resonance Images (MRI)
In this paper we present a hybrid approach based on combining fuzzy clustering, seed region growing, and Jaccard similarity coefficient algorithms to measure gray (GM) and white matter tissue (WM) volumes from magnetic resonance images (MRIs). The proposed algorithm incorporates intensity and anatomic information for segmenting of MRIs into different tissue classes, especially GM and WM. It sta...
متن کاملLipid composition of the normal human brain: gray matter, white matter, and myelin.
Gray matter, white matter, and myelin were isolated from the frontal lobes of humans aged 10 months, 6 yr, 9 yr, and 55 yr and the lipid compositions of each were determined. Myelin had a much higher lipid content (7841% of the dry weight) than white matter (49-66%) or gray matter (36-400/,). Myelin contained much higher molar percentages of cerebroside and cerebroside sulfate, slightly higher ...
متن کاملattenuation of brain white matter lesions after lacunar stroke
white matter lesions (wmls) are commonly observed in strokepatients with small vessel disease (svd) and are thought toresult from a progressive, irreversible disease process followingarteriolosclerosis. in this study, we report a case of partialdisappearance of wmls 1 year after a lacunar stroke in a69-year-old man with evidence of svd. we also discuss possiblemechanisms associated with this ob...
