Regional Gray Matter Volume Reduction Associated with Major Depressive Disorder: A Voxel-Based Morphometry
Major depressive disorder (MDD) is a typical and serious mental disorder such that lifetime prevalence reaches up to 16%, and 12-months prevalence is about 6.6%, and present various symptoms, including behavioral, cognitive, and emotional manifestations (1-3). The associations between the low emotional regulation which is the key feature of depressed patients and the structural changes such as ...
متن کاملVoxel-based morphometry in opera singers: Increased gray-matter volume in right somatosensory and auditory cortices
In contrast to instrumental musicians, professional singers do not train on a specific instrument but perfect a motor system that has already been extensively trained during speech motor development. Previous functional imaging studies suggest that experience with singing is associated with enhanced somatosensory-based vocal motor control. However, experience-dependent structural plasticity in ...
متن کاملRegional gray matter changes in major depressive disorder: an optimized voxel-based morphometry study
Introduction Voxel based morphometry (VBM) is a neuroimaging analysis technique that allows investigation of focal differences in brain anatomy, using the statistical approach of so-called statistical parametric mapping [1,2]. Major depressive disorder (MDD) is a common and serious psychiatric illness. In past study, the authors have done many researches to reveal the change in grey matter [3-7...
متن کاملGray and white matter reduction in hyposmic subjects--A voxel-based morphometry study.
The absence of olfactory input causes structural brain remodelling in humans. Mainly, the olfactory bulb and cortical olfactory areas are involved in this process. The aim of our study was to investigate volume changes of the gray and white matter in a group of subjects with an impaired but not complete loss of olfaction (hyposmia). Magnetic resonance images of hyposmic subjects and an age- and...
متن کاملVoxel-based morphometry shows no decreases in cerebellar gray matter volume in essential tremor.
OBJECTIVE To investigate cerebellar gray matter volume in patients with essential tremor (ET). METHODS We used voxel-based morphometry (VBM) based on high-resolution T1-weighted MRI to compare gray and white matter density between 27 patients with ET and 27 age- and sex-matched healthy control subjects. Fourteen patients had only postural tremor, whereas 13 patients showed additional intentio...
