White matter structure of human brain (taken by MRI).Anterior on the right. White matter refers to areas of the central nervous system (CNS) that are mainly made up of myelinated axons, also called tracts. [1]

The uncinate fasciculus is a white matter association tract in the human brain that connects parts of the limbic system such as the temporal pole, anterior parahippocampus, and amygdala in the temporal lobe with inferior portions of the frontal lobe such as the orbitofrontal cortex.
However, detailed analyses of white matter microstructure revealed that superagers had higher fractional anisotropy and lower mean diffusivity — two measures related to brain decline at a ...
It is the largest white matter structure in the human brain, about 10 cm (3.9 in) in length and consisting of 200–300 million axonal projections. [2] [3] A number of separate nerve tracts, classed as subregions of the corpus callosum, connect different parts of the hemispheres.
The brain can thus be described as being divided into left and right cerebral hemispheres. Each of these hemispheres has an outer layer of grey matter, the cerebral cortex, that is supported by an inner layer of white matter. In eutherian (placental) mammals, the hemispheres are linked by the corpus callosum, a very large bundle of nerve fibers.
The arbor vitae / ˌ ɑːr b ɔːr ˈ v aɪ t iː / (Latin for "tree of life") is the cerebellar white matter, so called for its branched, tree-like appearance.In some ways it more resembles a fern and is present in both cerebellar hemispheres. [1]
