Voxel-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 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 کاملStructural Differences in Gray Matter between Glider Pilots and Non-Pilots. A Voxel-Based Morphometry Study
Glider flying is a unique skill that requires pilots to control an aircraft at high speeds in three dimensions and amidst frequent full-body rotations. In the present study, we investigated the neural correlates of flying a glider using voxel-based morphometry. The comparison between gray matter densities of 15 glider pilots and a control group of 15 non-pilots exhibited significant gray matter...
متن کاملAdjusting for global effects in voxel-based morphometry: Gray matter decline in normal aging
Results from studies that have examined age-related changes in gray matter based on structural MRI scans have not always been consistent. Reasons for this variability likely include small or unevenly-distributed samples, different methods for tissue class segmentation and spatial normalization, and the use of different statistical models. Particularly relevant to the latter is the method of adj...
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...
