Multi-spectral segmentation of magnetic resonance images into grey matter (GM), white matter (WM) and CSF was performed on cross-sectional image data using a custom template and calculated prior probability maps. Global differences were evaluated by fitting a regression model for absolute and ...
and left striatum.Interestingly, the white matter tract changesin NFV-PPA were not confined to the insula,instead there was additional involvementof striatal and VMPFC white matter tracts, inparticular the anterior corpus callosum. Thisfinding is intriguing, as it suggests a dissociationof grey and...
Next, we reconstructed the brain morphology of each fossil cranium based on computational anatomy image processing techniques. In brief, the 3D structure of the brain (grey and white matter regions) and endocast (brain and cerebrospinal fluid regions) were obtained by segmenting 1,185 cranial MRI...

Although it has been reported that age-related changes in occipital regions of both cortex/grey matter and white matter are smaller compared with other regions34–37, it has also been found that within the occipital region, aging reduces the surface size of earlier visual cortex to a greater ...

Aging can cause damage to support cells in the white matter, which in turn may lead to damage in the grey matter of the hippocampus. A new study not only confirms that aging leads to both grey matter decline in the hippocampus and white matter decline in the surrounding area, but also re...
