Brain [r]: The core unit of a central nervous system. ^[e]
Morphometry [r]: The quantitative study of shapes. ^[e]
Computer graphics [r]: The generating, processing or interpreting of images by means of algorithms executed on a computer. ^[e]
Neuroimaging [r]: A group of techniques used to visualize structure and function of nervous systems, especially the vertebrate brain. ^[e]
Brain morphometry [r]: The quantitative study of structures in the brain, their differences between individuals, correlations with brain function, and changes of these characteristics over time. ^[e]

Surface reconstruction [r]: The conversion of a boundary in a three-dimensional raster image into a surface mesh. ^[e]
Surface inflation [r]: Add brief definition or description
White matter surface [r]: The boundary between white and grey matter of the cerebral cortex, as reconstructed from neuroimaging data. ^[e]
Central surface [r]: 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. ^[e]
Pial surface [r]: 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. ^[e]
Sulcal depth [r]: A measure of the maximal distance between the bed of a sulcus and an imaginary surface connecting the two adjacent gyri. ^[e]
Cortical thickness [r]: The combined thickness of the cerebral cortex layers. ^[e]

Voxel-based morphometry [r]: A variant of brain morphometry in which digital images of brains are compared on the basis of properties of groups of voxels. ^[e]
Deformation-based morphometry [r]: A variant of brain morphometry in which digital images of brains are compared on the basis of the deformations required to register them onto a common template. ^[e]

Topology correction [r]: A set of procedures in computer graphics that correct inconsistencies in the topology of a surface mesh that has been obtained from noisy imaging data. ^[e]
Spherical harmonics [r]: A series of harmonic basis functions that can be used to describe the boundary of objects with spherical topology. ^[e]
Spherical wavelets [r]: Add brief definition or description
Unit sphere [r]: Add brief definition or description
