Pial surface/Related Articles
Pial surface: A surface representing the boundary between grey matter and cerebrospinal fluid, as reconstructed from neuroimaging data; roughly corresponds to the position of the pia mater.
This article contains just a definition and optionally other subpages (such as a list of related articles), but no metadata. if you want to expand this into a full article.
- Brain morphometry : The quantitative study of structures in the brain, their differences between individuals, correlations with brain function, and changes of these characteristics over time.
- Surface-based morphometry : A set of computer graphics techniques used to analyze the surface structure of the brain.
- White matter : A subset of brain tissue whose volume is dominated by myelinated axons of nerve cells.
- Grey matter : A subset of brain tissue that contains few myelinated axons but the somas of nerve cells, as well as glia and endothelial structures.
- Surface reconstruction : The conversion of a boundary in a three-dimensional raster image into a surface mesh.
- Brain segmentation : In brain morphometry, the decomposition of an image of the brain into different classes of tissue, e.g. white matter, grey matter or cerebrospinal fluid.
- Central surface : A surface in between the pial surface and the white matter surface of the cerebral cortex, as reconstructed from neuroimaging data; roughly corresponds to the cortical lamina IV.
- White matter surface : The boundary between white and grey matter of the cerebral cortex, as reconstructed from neuroimaging data.
- Pia mater : The innermost of the meninges; surrounds the entire brain and spinal cord, descends into sulci.
- Cerebrospinal fluid : The liquid in which the central nervous system is embedded.
