White matter is composed of bundles, which connect various grey matter areas (the locations of nerve cell bodies) of the brain to each other, and carry nerve impulses between neurons. Myelin acts as an insulator, which allows electrical signals to jump , rather than coursing through the axon, increasing the speed of transmission of all nerve ...
Evidence from subcortical small infarcts suggests that motor fibers are somatotopically arranged in the human corona radiata. Following subtotal brain damage, localization of the corticofugal projection in the corona radiata and internal capsule can assist in evaluating a patient's residual motor capacity and predicting their potential for functional restitution.

In neuroanatomy, the centrum semiovale, semioval center or centrum ovale [1] is the central area of white matter found underneath the cerebral cortex. [2] The white matter, located in each hemisphere between the cerebral cortex and nuclei, as a whole has a semioval shape.
For example, deep white matter hyperintensities are 2.5 to 3 times more likely to occur in bipolar disorder and major depressive disorder than control subjects. [3] [4] WMH volume, calculated as a potential diagnostic measure, has been shown to correlate to certain cognitive factors. [5]
Location of infarct Presentation Pure motor stroke/hemiparesis (most common lacunar syndrome: 33–50%) posterior limb of the internal capsule, basilar part of pons, corona radiata It is marked by hemiparesis or hemiplegia that typically affects the face, arm, or leg of the side of the body opposite the location of the infarct.

The internal capsule is a paired white matter structure, as a two-way tract, carrying ascending and descending fibers, to and from the cerebral cortex. The internal capsule is situated in the inferomedial part of each cerebral hemisphere of the brain. It carries information past the subcortical basal ganglia.
